# Brian May

Sir Brian Harold May (born 19 July 1947) is an English musician, songwriter, record producer, animal welfare activist and astrophysicist. He achieved global fame as the lead guitarist and backing vocalist of the rock band Queen, which he co-founded with singer Freddie Mercury and drummer Roger Taylor. His guitar work and songwriting contributions helped Queen become one of the most successful acts in music history.
May previously performed with Taylor in the progressive rock band Smile, which he had joined while he was at university. After Mercury joined to form Queen in 1970, bass guitarist John Deacon completed the line-up in 1971. They became one of the biggest rock bands in the world with the success of the album A Night at the Opera and its single "Bohemian Rhapsody". From the mid-1970s until 1986, Queen played at some of the biggest venues in the world, including an acclaimed performance at Live Aid in 1985. As a member of Queen, May became regarded as a virtuoso musician and was identified with a distinctive sound created through his layered guitar work, often using a home-built electric guitar called the Red Special. May wrote numerous hits for Queen, including "We Will Rock You", "I Want It All", "Fat Bottomed Girls", "Flash", "Hammer to Fall", "Save Me", "Who Wants to Live Forever" and "The Show Must Go On".
Following the death of Mercury in 1991, aside from the 1992 tribute concert, the release of Made in Heaven (1995) and the 1997 tribute single to Mercury, "No-One but You (Only the Good Die Young)" (written by May), Queen were put on hiatus for several years but were eventually reconvened by May and Taylor for further performances featuring other vocalists. In 2005, a Planet Rock poll saw May voted the seventh-greatest guitarist of all time. He was ranked at No. 33 on Rolling Stone's 2023 list of 250 greatest guitarists of all time. In 2012, he was further ranked the second-greatest guitarist in a Guitar World magazine readers poll. In 2001, May was inducted into the Rock and Roll Hall of Fame as a member of Queen and, in 2018, the band received the Grammy Lifetime Achievement Award.
May was appointed a Commander of the Most Excellent Order of the British Empire (CBE) in 2005 for services to the music industry and for charity work. May earned a PhD degree in astrophysics from Imperial College London in 2007, and was Chancellor of Liverpool John Moores University from 2008 to 2013. He was a "science team collaborator" with NASA's New Horizons Pluto mission. He is also a co-founder of the awareness campaign Asteroid Day. Asteroid 52665 Brianmay was named after him. In 2023, May contributed to NASA's OSIRIS-REx mission, the agency's first successful collection and earth delivery of samples directly from an asteroid (the asteroid Bennu). May is also an animal welfare activist, campaigning against fox hunting and the culling of badgers in the UK. May was knighted by King Charles III in the 2023 New Year Honours for services to music and charity.

## Early life

Brian Harold May was born on 19 July 1947 at Gloucester House Nursing Home in Hampton Hill, near Twickenham, Middlesex. He is the only child of Ruth Irving (née Fletcher) and Harold May, who worked as a draughtsman at the Ministry of Aviation. His mother, who was Scottish, married his father, who was English, at Moulin in Perthshire, Scotland in 1946. May attended the local Hanworth Road state primary school, and at the age of 11 won a scholarship to Hampton Grammar School, then a voluntary aided school. During this time, he formed his first band, named 1984 after George Orwell's novel Nineteen Eighty-Four, with vocalist and bassist Tim Staffell.
At Hampton Grammar School, May attained ten GCE Ordinary Levels and three GCE Advanced Levels in physics, mathematics, and applied mathematics. He studied mathematics and physics at Imperial College London, graduating with a BSc degree in physics in 1968 with honours. Following his graduation, May received a personal invitation from Sir Bernard Lovell to work at the Jodrell Bank Observatory while continuing to prepare his doctorate. He declined, choosing instead to remain at Imperial College to avoid breaking from Smile, the London-based band he was in at the time.
In 2007, May earned a PhD degree in astrophysics from Imperial College London for work started in 1971.

## Musical career
### 1968–1970: Smile

May formed the band Smile in 1968. The group included Tim Staffell as the lead singer and bassist, and later, drummer Roger Taylor, who also went on to play for Queen. The band lasted for only two years, from 1968 to 1970, as Staffell departed in 1970, leaving the band with a catalogue of nine songs. Smile would reunite for several songs on 22 December 1992. Taylor's band The Cross were headliners, and he brought May and Staffell on to play "Earth" and "If I Were a Carpenter". May also performed several other songs that night.

### 1970–1995: Queen

In Queen's three-part vocal harmonies, May was generally the lower-range backing vocalist. On some of his songs, he sings the lead vocals, most notably the first verse of "Who Wants to Live Forever", the final verse of "Mother Love", the middle eight on "I Want It All" and "Flash's Theme", and full lead vocals on "Some Day One Day", "She Makes Me (Stormtrooper in Stilettoes)", "'39", "Good Company", "Long Away", "All Dead, All Dead", "Sleeping on the Sidewalk", "Leaving Home Ain't Easy" and "Sail Away Sweet Sister" .
May frequently wrote songs for the band and has composed many hits such as "We Will Rock You", "Tie Your Mother Down", "I Want It All", "Fat Bottomed Girls", "Who Wants to Live Forever" and "The Show Must Go On" as well as "Hammer to Fall", "Flash", "Now I'm Here", "Brighton Rock", "The Prophet's Song", "Las Palabras de Amor", "No-One but You (Only the Good Die Young)" and "Save Me".
After the Live Aid concert in 1985, Mercury rang his band members and proposed writing a song together. The result was "One Vision", which was basically May on music (the Magic Years documentary shows how he came up with the opening section and the basic guitar riff); the lyrics were co-written by the four band members.
For their 1989 release album, The Miracle, the band had decided that all of the tracks would be credited to the entire band, no matter who had been the main writer. Interviews and musical analyses tend to help identify the input of each member on each track. May composed "I Want It All" for that album, as well as "Scandal" (based on his problems with the British press). For the rest of the album, he did not contribute much creatively. However, he helped in building the basis of "Party" and "Was It All Worth It" (both being predominantly Mercury's pieces) and created the "Chinese Torture" guitar riff.
Queen's subsequent album was Innuendo. May's contributions increased, although more in terms of arranging than actual writing in most cases. He did some of the arrangement for the heavy solo on the title track. He added vocal harmonies to "I'm Going Slightly Mad" and composed the solo for "These Are the Days of Our Lives", a song for which the four of them decided the keyboard parts together.
Two songs May had composed for his first solo album, "Headlong" and "I Can't Live With You", eventually ended up on the Queen project. His other composition was "The Show Must Go On", which he coordinated and was the primary composer. In recent years, he has supervised the remastering of Queen albums and various DVD and greatest hits releases. In 2004, he announced that he and drummer Roger Taylor were going on tour for the first time in 18 years as "Queen", along with Free/Bad Company vocalist Paul Rodgers. Billed as "Queen + Paul Rodgers", the band played throughout 2005 and 2006 in South Africa, Europe, Aruba, Japan, and North America and released a new album with Rodgers in 2008, titled The Cosmos Rocks. This album was supported by a major tour.
Paul Rodgers left the band in May 2009. It was not until 2011 that another vocalist, Adam Lambert, was recruited. Queen + Adam Lambert toured Europe in 2012 and toured the world tour over 2014 and 2015. Their most recent outing was the 2016 Festival Tour. They also played the Big Ben New Year concert on New Year's Eve 2014 and New Year's Day 2015.

### 1983–1999: Side projects and solo works

During 1983, several members of Queen explored side projects. On 21 and 22 April in Los Angeles, May was in a studio with Eddie Van Halen, with no intention of recording anything. The result of the two-day session was a mini album titled Star Fleet Project, which was not originally going to be released. In 1986, May contributed to former Genesis guitarist Steve Hackett's album Feedback 86, playing guitar on the track "Cassandra" and providing guitar and vocals for "Slot Machine", which May co-wrote. Although produced in 1986, the album was not released commercially until 2000. Another song co-written by May and Hackett during this period, "Don't Fall Away from Me", was eventually recorded by Hackett in 1992 for release on his The Unauthorised Biography compilation album. Also in 1986, May worked with actress Anita Dobson on her first album, most noted for the song "Anyone Can Fall in Love", which added lyrics to the EastEnders theme tune and reached number four on the UK Singles Chart in August 1986. May and Dobson married in 2000. In 1988, May contributed guitar solos to the song "When Death Calls" on Black Sabbath's 14th album Headless Cross, and the Living in a Box track "Blow The House Down" on the album Gatecrashing. Both albums were released in 1989.
   After the tragic break-up of any band, it feels impossible to continue but I was really glad that Brian did launch a solo career. He had such a lot of music in him and a great deal more to give.
In the aftermath of the November 1991 death of Mercury, May chose to deal with his grief by committing himself as fully as possible to work, first by finishing his solo album, Back to the Light, and then touring worldwide to promote it. He frequently remarked in press interviews that this was the only form of self-prescribed therapy he could think of. According to Def Leppard lead singer Joe Elliott, "It was undoubtedly an enormous and terrible blow to lose someone he was so close to. Personally, I know it ripped the heart out of Brian, but having said that, he was in great spirits after the album was finished." Back to the Light featured the single "Too Much Love Will Kill You", on which he collaborated as a songwriter with Frank Musker and Elizabeth Lamers. A version with Freddie Mercury's vocals was later released on the Queen album Made in Heaven and won the Ivor Novello Award for Best Song Musically & Lyrically in 1996.
In late 1992, the Brian May Band was officially formed. May had loosely formed an earlier version of the band for 19 October 1991, when May took part in the Guitar Legends guitar festival in Seville, Spain. The line-up for his performance was May on vocals and lead guitar, Cozy Powell on drums and percussion, Mike Moran and Rick Wakeman on keyboards, and Maggie Ryder, Miriam Stockley and Chris Thompson on backing vocals. The original line-up was May on vocals and lead guitar, Powell on drums and percussion, Michael Casswell on guitar, Neil Murray on bass, and Ryder, Stockley and Thompson on backing vocals. This version of the band was together only during the South American support tour (supporting The B-52's and Joe Cocker) on five dates.
May later made significant changes, feeling the group never quite gelled. May brought guitarist Jamie Moses on board to replace Mike Caswell. The backing vocalists, Ryder, Stockley and Thompson, were replaced by Catherine Porter and Shelley Preston. On 23 February 1993, this new line-up of The Brian May Band began its world tour in the US, supporting Guns N' Roses and headlining a few dates. The tour included dates in North America, Europe (support act: Valentine) and Japan. On 15 June 1993, the band did a show in London that would end up as The Brian May Band's only release as a collective, namely Live at the Brixton Academy. At the show, May would sing a few lines of "Love of My Life", and then, as Mercury used to, let the audience join in. After the tour ended on 18 December 1993, May returned to the studio with fellow surviving Queen band members Roger Taylor and John Deacon to work on tracks that became Made in Heaven, the final Queen studio album. The band took Mercury's solo album demos and last recordings, which he managed to perform in the studio after the album Innuendo was finished, and completed them with their additions both musically and vocally. After Mercury's death, work on the album by Deacon and May began originally in 1992 but was left until a later date due to other commitments.
In 1995, May began working on a new solo album of covers tentatively titled Heroes, in addition to working on various film and television projects and other collaborations. May subsequently changed the approach from covers to focus on those collaborations and new material. The songs included Another World, and featured mainly Spike Edney, Cozy Powell, Neil Murray and Jamie Moses. On 5 April 1998, Cozy Powell was killed in a car accident on the M4 motorway near Bristol, England. This incident caused an unexpected disruption to the upcoming tour for the Brian May Band, which now needed a new drummer on short notice. Steve Ferrone was brought on to help May finish recording the drum tracks and join the band for the early stage promotional tour of five dates in Europe before the world tour. Following the early promotional tour, Eric Singer replaced him on the 1998 world tour.
The 1998 tour saw the brief introduction of a 'support act' known as T. E. Conway. Conway (Brian May in a wig and colourful suit playing the part of a teddy boy crooner) would play several 1950s rock and roll standards before May's 'arrival'. A bonus T. E. Conway EP titled Retro Rock Special was attached to some pressings of the Another World album. The Conway character was retired at the end of the tour. In May 1999, May recorded lead guitars for the Guns N' Roses song "Catcher in the Rye" on Chinese Democracy, but his performance was removed from the album by the time it was released in 2008.

### 2000–2010

From his last solo release in 1998, May has been performing as a solo artist, as part of an ensemble, and infrequently as Queen with Roger Taylor. On 22 October 2000, he made a guest appearance at the Motörhead 25th Anniversary show at Brixton Academy along with Eddie Clarke (former Motörhead guitarist) for the encore song "Overkill". As part of the Golden Jubilee of Elizabeth II celebrations on 3 June 2002, May performed a guitar solo of "God Save the Queen" from the roof of Buckingham Palace, with the performance appearing on the 30th Anniversary DVD edition of A Night at the Opera. May played guitar on the song "Someone to Die For" on the Spider-Man 2 soundtrack in 2004.
On the Queen's birthday honours list of 2005, he was made a Commander of the Most Excellent Order of the British Empire "for services to the music industry and for charity work". In the same year he played the guitar on the song Il mare... for Italian singer Zucchero Fornaciari, on his album Zu & Co., and he took part in the concert at the Royal Albert Hall in London held in May 2004, with the other guests of the Italian bluesman. May was a celebrity guest at the Genesis reunion concert at Twickenham Stadium in 2007. May and Genesis frontman Phil Collins worked together on two previous occasions, at The Prince's Trust Rock Gala in 1988 and the Party at the Palace in 2002, when Collins had played drums with Queen. In 2011 he contributed to a feature about Collins for FHM, praising him as "a great guy and an amazing drummer".
During the late 1960s, May became an enthusiast of stereoscope photographs, as a child, and first encountered the work of Thomas Richard Williams. In 2003, May announced a search to identify the actual location of the Scenes in Our Village images. In 2004 May reported that he had identified the location as the village of Hinton Waldrist in Oxfordshire. Along with Elena Vidal, May released a historical book in 2009 titled A Village Lost and Found: Scenes in Our Village. The book is an annotated collection of stereoscopic photographs taken by the Victorian era photographer T. R. Williams. It included a focusing stereoscope. May used a 3D camera to document the history of Queen.
May worked extensively with stage actress and singer Kerry Ellis after he cast her in the musical We Will Rock You. He produced and arranged her debut studio album Anthems (2010), a follow-up to her extended play Wicked in Rock (2008), as well as appearing with Ellis at many public performances—playing guitar alongside her. He also contributed a guitar solo to Meat Loaf's Hang Cool, Teddy Bear album in exchange for the use of drummer John Miceli.
On 20 May 2009, May and Queen bandmate Roger Taylor performed "We Are the Champions" live on the season finale of American Idol with winner Kris Allen and runner-up Adam Lambert providing a vocal duet. In November 2009, May appeared with Taylor on The X Factor, with Queen mentoring the contestants, then later performed "Bohemian Rhapsody". In April 2010, May founded the "Save Me" 2010 project to work against any proposed repeal of the British fox-hunting ban, and to promote animal welfare in Britain. In February 2011, it was announced that May would tour with Kerry Ellis, playing 12 dates across the UK in May 2011.

### 2004–2009: Queen + Paul Rodgers

At the end of 2004, May and Taylor announced that they would reunite and return to touring in 2005, with Paul Rodgers, the founder and former lead singer of Free and Bad Company. Brian May's website also stated that Rodgers would be "featured with" Queen as Queen + Paul Rodgers, not replacing the late Freddie Mercury. The retired John Deacon would not be participating.
Between 2005 and 2006 Queen and Paul Rodgers embarked on a world tour, the first leg being Europe and the second, Japan and the US in 2006. On 25 May 2006, Queen received the inaugural VH1 Rock Honors at the Mandalay Bay Events Center in Las Vegas, Nevada, and May and Taylor were joined on stage with the Foo Fighters to perform a selection of Queen songs. On 15 August 2006, May confirmed through his website and fan club that Queen + Paul Rodgers would begin producing their first studio album in October, to be recorded at a "secret location". The album, titled The Cosmos Rocks, was released in Europe on 12 September 2008 and in the United States on 28 October 2008. Following the album's release, the band embarked on a tour through Europe and parts of the US, opening on Kharkiv's freedom square in front of 350,000 Ukrainian fans. The show in Ukraine was later released on DVD. Queen and Paul Rodgers officially split up on 12 May 2009. Rodgers did not rule out the possibility of working together again.

### 2011–present

On 18 April 2011, Lady Gaga confirmed that May would play guitar on her track "You and I" from her latest album Born This Way, released on 23 May 2011. May joined Gaga on stage during the performance of "You and I" at the 2011 MTV Video Music Awards held at Nokia Theatre in Los Angeles. May performed with Tangerine Dream at the Starmus Festival on Tenerife in June 2011, celebrating the 50th anniversary of Yuri Gagarin's first spaceflight.
May performed "We Will Rock You" and "Welcome to the Black Parade" with the rock band My Chemical Romance at the Reading Festival on 26 August 2011. On 10 October, May made an appearance to celebrate the reunion of rock band The Darkness at an "intimate" 100 Club show with support from Dark Stares. A long-time fan of the group, May performed three songs onstage with The Darkness, including Queen's "Tie Your Mother Down", at the Hammersmith Apollo on their subsequent "comeback" tour.
At the 2011 MTV Europe Music Awards on 6 November, Queen received the Global Icon Award, which Katy Perry presented to Brian May. Queen closed the awards ceremony, with Adam Lambert on vocals, performing "The Show Must Go On", "We Will Rock You" and "We Are the Champions". The collaboration garnered a positive response from both fans and critics, resulting in speculation about future projects together. Queen + Adam Lambert played two shows at the Hammersmith Apollo, London, on 11 and 12 July 2012. Both shows sold out within 24 hours of tickets going on open sale. A third London date was added for 14 July. On 30 June, Queen + Lambert performed in Kyiv, Ukraine at a joint concert with Elton John for the Elena Pinchuk ANTIAIDS Foundation. Queen also performed with Lambert on 3 July 2012 at Moscow's Olympic Stadium, and on 7 July 2012 at the Municipal Stadium in Wroclaw, Poland.
In January 2012, May featured on N-Dubz frontman Dappy's solo single "Rockstar", providing "rumbling guitar riffs which culminate in an electrifying solo". The pair also collaborated on a performance of "We Will Rock You" for BBC Radio 1's Live Lounge.
Queen performed at the closing ceremony of the 2012 Summer Olympics in London on 12 August 2012. May performed part of the "Brighton Rock" solo before being joined by Taylor and solo artist Jessie J for a performance of "We Will Rock You". On 16 September 2012, May appeared at the Sunflower Jam charity concert at the Royal Albert Hall, performing alongside bassist John Paul Jones (of Led Zeppelin), drummer Ian Paice (of Deep Purple), and vocalists Bruce Dickinson (of Iron Maiden) and Alice Cooper.
In a 2013 West End run of Spamalot (the musical adaptation of Monty Python's 1975 film Monty Python and the Holy Grail), May was among the celebrities who played the part of voicing God for a week in aid of charity. In 2015, May played guitar on the end credits song "One Voice" from the film A Dog Named Gucci. The song also features the talents of: Norah Jones, Aimee Mann, Susanna Hoffs, Lydia Loveless, Neko Case, and Kathryn Calder. It was produced by Dean Falcone, who wrote the film's score. "One Voice" was released on Record Store Day, 16 April 2016, with profits from the sale of the single going to benefit animal charities.
Welsh electronic musician Jayce Lewis collaborated with May in 2018 on the song We Are One, taken from Lewis' 2018 album release Million. Incorporating a repurposed Finger tapping/Hammering riff from May's solo track Cyborg from his album; Another World (Brian May album), both artists re-recorded May's guitar at a slower speed, and included it to the new song composition.
On 29 March 2019, May inducted Def Leppard into the Rock and Roll Hall of Fame. He worked with contemporary metal band Five Finger Death Punch and blues artist Kenny Wayne Shepherd to re-record a new version of "Blue on Black" in support of The Gary Sinise Foundation in April 2019. The artists came together to merge country and mainstream rock to re-create the classic song originally co-written by Shepherd.
In 2024, May contributed guitar to a re-release of Mark Knopfler's "Going Home: Theme of the Local Hero" in aid of the Teenage Cancer Trust.

#### Queen + Adam Lambert

Not long after performing with American Idol finalists Kris Allen and Adam Lambert during the programme's season finale in 2009, May and Taylor began contemplating the future of Queen after the group's amicable split with frontman Paul Rodgers. At the 2011 MTV Europe Music Awards, Queen was presented with that year's Global Icon Award, accepted by May. As part of the broadcast, Queen performed a short set with Lambert, receiving an overwhelmingly welcoming response. Speculation regarding collaboration with Lambert soon arose, with the three formally announcing a short summer tour of Europe in 2012, including three dates at the Hammersmith Apollo in London, as well as shows in Ukraine, Russia and Poland.
The collaboration was revived in 2013, when the three performed together at the iHeartRadio Music Festival at the MGM Grand Hotel & Casino in Las Vegas on 20 September. Five months later, May, Taylor and Lambert announced a 19-date summer tour of North America on Good Morning America. Because of ticket demand, five dates were soon added. In May 2014, shows in Australia and New Zealand were announced, along with festival performances in South Korea and Japan. The tour was extended to the UK and greater Europe in early 2015. The group performed together in South America in September 2015, including Queen's first performance at the Rock in Rio Festival since 1985.
In 2016, the group embarked across Europe and Asia on the Queen + Adam Lambert 2016 Summer Festival Tour. This included closing the Isle of Wight Festival in England on 12 June where they performed "Who Wants to Live Forever" as a tribute to the victims of the mass shooting at a gay nightclub in Orlando, Florida earlier that day. On 12 September they performed at the Yarkon Park in Tel Aviv, Israel for the first time in front of 58,000 people. In September 2018 the group had a residency in the MGM Park Theater in Las Vegas. Though the collaboration remains active, there are currently no plans to record a studio album, though the three are willing to do so in the future. On 31 March 2020, Queen + Adam Lambert confirmed that their touring dates were postponed until 2021 because of the global COVID-19 pandemic.
On 4 June 2022, Queen + Adam Lambert opened the Platinum Party at the Palace outside Buckingham Palace to mark the Platinum Jubilee of Elizabeth II. Performing a three-song set, May appeared in front of the Victoria Memorial monument as they opened with "We Will Rock You" which had been introduced in a comedy segment where the Queen and Paddington Bear tapped their tea cups to the beat of the song.

## Musicianship
### Guitar style

   I can listen to any player and pantomime their sound, but I can't do Brian May. He's just walking on higher ground.
   His tone immediately grabbed me. Brian has his own style and sound, so you can always tell his work. Even in 1971 he had incredible finesse, amazing fluidity.
May has been referred to as a virtuoso guitarist by many publications and musicians. He has featured in various music polls of the greatest rock guitarists, and in 2011 was ranked number 26 on Rolling Stone magazine's list of the "100 Greatest Guitarists of All Time". In January 2007, the readers of Guitar World voted May's guitar solos on "Bohemian Rhapsody" and "Brighton Rock" into the "top 50 Greatest Guitar Solos of all time" (No.20 and No.41 respectively). Former Van Halen vocalist Sammy Hagar stated, "I thought Queen were really innovative and made some great sounding records... I like the rockin' stuff. I think Brian May has one of the great guitar tones on the planet, and I really, really love his guitar work." Justin Hawkins, lead guitarist of the Darkness, cites May as his earliest influence, saying "I really loved his tone and vibrato and everything. I thought his playing sounded like a singing voice. I wanted to be able to do that. Whenever I went to guitar lessons, I was always asking to learn Queen stuff."
American guitar virtuoso Steve Vai has spoken highly of May's work, saying:
   In that whole genre, in that whole period—he's one of the most unique contributors. He doesn't get credit. Because what he does is so rich and so specific, and so deep, it fits so well in Queen music, you just feel it as part of that music. But when you break it down and when you look at it from a guitar player's point of view, it's unique, and nobody to this date could do what he does and make it sound like that. He is an iconic player. His tone, his choice of melody notes, he doesn't just do solos. His solos are melodies, and they're perfectly in place.
Most of May's electric guitar work live and in the studio is done on the Red Special, which he built with his father, an electronics engineer, when he was sixteen years old. It was built with wood from an 18th-century fireplace, and was composed of household items such as mother-of-pearl buttons, shelf edging, and motorbike valve springs. While May and his father were building the Red Special, May also produced plans to build a second guitar. However, the Red Special was so successful that May did not need to build another guitar. These plans were eventually given to guitar luthier Andrew Guyton in around 2004–05. Guyton made some slight modifications and the guitar was built. It was named "The Spade" as the body's shape resembled the form shown on playing cards. The guitar also came to be known as "The Guitar That Time Forgot".
May commented on the Red Special:
   I like a big neck – thick, flat and wide. I lacquered the fingerboard with Rustin's Plastic Coating. The tremolo is interesting in that the arm's made from an old bicycle saddle bag carrier, the knob from the ends of a knitting needle, and the springs are valve springs from an old motorbike.
In addition to using his home-made guitar he prefers to use coins (especially a sixpence from the farewell proof set of 1970), instead of a more traditional plastic plectrum, because he feels their rigidity gives him more control in playing. He is known to carry coins in his pockets specifically for this purpose.
A meticulous arranger, he focuses on multi-part harmonies, often more contrapuntal than parallel—a relative rarity for rock guitar. Examples are found in Queen's albums A Night at the Opera and A Day at the Races, where he arranged a jazz band for guitar mini-orchestra ("Good Company"), a vocal canon ("The Prophet's Song") and guitar and vocal counterpoints ("Teo Torriatte").
May explored a wide variety of styles in guitar, including: sweep picking ("Was It All Worth It" "Chinese Torture"); tremolo ("Brighton Rock", "Stone Cold Crazy", "Death on Two Legs", "Sweet Lady", "Bohemian Rhapsody", "Get Down Make Love", "Dragon Attack"); tapping ("Bijou", "It's Late", "Resurrection", "Cyborg", "Rain Must Fall", "Business", "China Belle", "I Was Born To Love You"); slide guitar ("Drowse", "Tie Your Mother Down"); Hendrix sounding licks ("Liar", "Brighton Rock"); tape-delay ("Brighton Rock", "White Man"); and melodic sequences ("Bohemian Rhapsody", "Killer Queen", "These Are the Days of Our Lives"). Some of his solos and orchestral parts were composed by Freddie Mercury, who then asked May to bring them to life ("Bicycle Race", "Lazing on a Sunday Afternoon", "Killer Queen", "Good Old Fashioned Lover Boy"). May also performed notable acoustic works, including the finger-picked solo of "White Queen" (from Queen II), "Love of My Life" and the skiffle-influenced "'39" (both from A Night at the Opera).
Aided by the uniqueness of the Red Special, May was often able to create strange and unusual sound effects. For example, he was able to imitate an orchestra in the song "Procession"; in "Get Down, Make Love" he was able to create various sound effects with his guitar; in "Good Company" he used his guitar to mimic a trombone, a piccolo and several other instruments for the song's Dixieland jazz band feel. Queen used a "No synthesizers were used on this album" sleeve note on their early albums to make this clear to the listeners. May also used his guitar to create the chime effect in "Bohemian Rhapsody".

### Influences

May's early influences included Cliff Richard and the Shadows, who he says were "the most metallic thing(s) out at the time". Many years later he gained his opportunity to play on separate occasions with the Shadows' lead guitarist Hank Marvin. He has collaborated with Richard on a re-recording of 1958 hit "Move It" on Richard's duets album Two's Company, which was released on 6 November 2006.
May always stated that the Beatles, Led Zeppelin, the Who and Jimi Hendrix were the greatest influences on him. On the Queen for an Hour interview on BBC Radio 1 in 1989, May listed Hendrix, Jeff Beck and Eric Clapton as his guitar heroes. In a 1991 interview for Guitar World magazine, May referred to the Who as "my inspiration", and on seeing Led Zeppelin stated, "We used to look at those guys and think, 'That's the way it should be done.'" May told Guitarist in 2004, "I don't think anyone has epitomised riff writing better than Jimmy Page – he's one of the great brains of rock music".
May also cites Rory Gallagher as a major influence, saying "He was a magician. He was one of the very few people of that time who could make his guitar do anything, it seemed. I remember looking at that battered Stratocaster and thinking, 'How does that (sound) come out of there?'" According to May, "... it was Rory that gave me my sound, and that's the sound I still have." May was also influenced by Steve Hackett, guitarist of the progressive rock band Genesis, in particular his harmony guitar solo at the end of the band's epic 1971 song "The Musical Box". Hackett said of May, "Equally, his energetic approach to guitar inspired me."

### Equipment
#### Guitars

From 1975 onwards, May had some replicas made of the Red Special, some of which were also used for live and recording purposes, others being mainly spares. The most famous replicas were made by John Birch in 1975 (May smashed it during a concert in the US in 1982), Greco BM90 (featured in the promo video of "Good Old-Fashioned Lover Boy" in 1977), Guild (back-up from 1984 to 1993), Fryers (1997–1998, used both live and in the studio) and Guyton (back-up from 2003 to present). On stage, May used to carry at least one backup guitar (in case he broke a string). He occasionally would use others for specific songs or parts, such as alternative tunings. Currently, May owns a company that makes guitars whose design is modelled after the original Red Special guitar.
* July 1973 – May 1974: Fender Stratocaster CBS era (thought to be 1972)
* October 1974 – May 1975: Gibson Les Paul Deluxe, and the Stratocaster from the previous tour.
* November 1975 – May 1976: Same two guitars as before, plus a natural finish John Birch replica of the Red Special.
* September 1976: Same three as before, plus a Martin D-18 acoustic for "'39".
* January 1977 – August 1979: Just the Birch replica plus an Ovation Pacemaker 12-string acoustic on some numbers ("'39", "Love of My Life", "Dreamer's Ball").
* November 1979 – June 1982: Birch replica (back-up), Fender Telecaster ("Crazy Little Thing Called Love" 2nd verse, middle-eight and solo), Ovation (acoustic numbers).
* July – November 1982: Added a Gibson Flying V as second back-up. On 9 August 1982, May smashed the Birch guitar, so the Flying V became the only spare.
* August – October 1984: The Flying V became a second back-up again as his main spare was the Guild replica. He also used Roger Taylor's Gibson Chet-Atkins Classical Electric.
* July 1985 – August 1986: Gibson Flying V no longer used. The rest remained the same. May used a Gibson Chet-Atkins guitar on the 1986 Magic Tour.
* In 2012, he received a double-neck replica of the Red Special, with the second neck having 12-strings. He used this guitar at a few gigs with Adam Lambert now being able to play the 12-string part from the studio version of "Under Pressure" live.
He currently has a Gibson 12-string SJ200 to replace his Guild 12-string. He previously used an Ovation Pacemaker 1615 model. Some of the non-RS electric guitars he used in the studio included:
* Burns Double Six on "Long Away" (1976) and "Under Pressure" (1981).
* Fender Telecaster on "Crazy Little Thing Called Love" (1979). May used it for the video (but not the recordings) of "Back Chat" (1982).
* Gibson Firebird on "Hammer to Fall" and "Tear It Up" (album versions only, not on stage).
* Ibanez JS on "Nothing But Blue" (1991).
* Parker Fly on "Mother Love" (1993–1995).
For acoustic, he favoured Ovation, Martin, Tōkai Hummingbird, Godin and Guild. On a couple of videos, he also used some different electric guitars: a Stratocaster copy on "Play the Game" (1980) and a Washburn RR2V on "Princes of the Universe" (1986).
In 1984, Guild released the first official Red Special replica for mass production and made some prototypes specifically for May. However, the solid-body construction (the original RS has hollow cavities in the body) and the pick-ups (DiMarzio) that were not a replica of the Burns TriSonic did not make May happy. The production of the guitars stopped after just 300 guitars. In 1993, Guild made a second replica of the RS, made in just 1000 copies, of which May has some and used as a back-up. At the moment, he uses the two guitars made by Greg Fryer—the luthier who restored the Old Lady in 1998—as back-up. They are almost identical to the original, except for the Fryer logo on the headstock (May's original one has a sixpence).

#### Amplifiers and effects

   I've never heard a guitar sound so loud! He had a wall of AC30s cranked, and it was like a jumbo jet taking off. It was phenomenal.
May has used Vox AC30 amplifiers almost exclusively since a meeting with his long-time hero Rory Gallagher at a gig in London during the late 1960s/early 1970s. In the mid-1970s he used six of them, with an Echoplex delay (with extended delay time) plugged into a separate amplifier, and a second Echoplex plugged into yet another amp; he used a homemade booster, his only effects pedal, which was on all the time. His choice is the model AC30TBX, the top-boost version with Blue Alnico speakers, and he runs the amp at full volume on the Normal channel.
May also customises his amps by removing the Brilliant and Vib-trem channels (leaving only the circuitry for the Normal). This alters the tone slightly, with a gain addition of 6–7 dB. He always used a treble booster which, along with the AC30 and his custom 'Deacy Amp' transistor amp, built by Queen bass player John Deacon, went a long way in helping to create many of his signature guitar tones. He used the Dallas Rangemaster for the first Queen albums, up to A Day at the Races. Effects designer Pete Cornish built for him the TB-83 (32 dB of gain) that was used for all the remaining Queen albums. He switched in 2000 to the Fryer's booster, which actually gives less boost than the TB-83.
When performing live, May uses banks of Vox AC30 amplifiers, keeping some amps with only guitar and others with all effects such as delay, flanger and chorus. He has a rack of 14 AC30s, which are grouped as Normal, Chorus, Delay 1, Delay 2. On his pedal board, May has a custom switch unit made by Cornish and subsequently modified by Fryer that allows him to choose which amps are active. He uses a BOSS pedal from the '70s, the Chorus Ensemble CE-1, which can be heard in "In The Lap of The Gods" (Live at Wembley '86) or "Hammer to Fall" (slow version played live with P. Rodgers). Next in the chain, he uses a Foxx Foot Phaser ("We Will Rock You", "We Are the Champions", "Keep Yourself Alive", etc.), and two delay machines to play his trademark solo in "Brighton Rock".

#### Piano and other instruments

As a child, May was trained on classical piano. Although Freddie Mercury was the band's primary pianist, May would step in occasionally (such as on "Save Me" and "Flash"). He mostly used Freddie Mercury's 1972 Steinway piano. From 1979 onwards, he also played synthesisers, organ ("Wedding March", "Let Me Live") and programmed drum-machines for both Queen and outside projects (such as producing other artists and his own solo records). In the studio, May used Yamaha DX7 synths for the opening sequence of "One Vision" and the backgrounds of "Who Wants to Live Forever" (also on stage), "Scandal" and "The Show Must Go On".
The first instrument May learned to play was the banjolele. He used a "genuine George Formby Ukulele-Banjo" in "Bring Back That Leroy Brown" and "Good Company". Occasionally, May would also record on other string instruments such as harp (one chord per take, then copied and pasted by the engineer to make it sound like a continuous performance) and bass (on some demos and many songs in his solo career, and the Queen + Paul Rodgers album). May was keen on using some toys as instruments as well. He used a Yamaha plastic piano in "Teo Torriatte" and a toy mini koto in "The Prophet's Song".

#### Vocals

May is also an accomplished singer. From Queen's Queen II to The Game, May contributed lead vocals to at least one song per album. May co-composed a mini-opera with Lee Holdridge, Il Colosso, for Steve Barron's 1996 film, The Adventures of Pinocchio. May performed the opera with Jerry Hadley, Sissel Kyrkjebo, and Just William. On-screen, it was performed entirely by puppets.

## Scientific career

May studied physics and mathematics at Imperial College London, graduating with a BSc (Hons) degree and ARCS in physics with Upper Second-Class Honours. From 1970 to 1974, he studied for a PhD degree at Imperial College, studying reflected light from interplanetary dust and the velocity of dust in the plane of the Solar System. When Queen began to have international success in 1974, he abandoned his doctoral studies, but nonetheless co-authored two peer-reviewed research papers, which were based on his observations at the Teide Observatory in Tenerife.
In October 2006, May re-registered for his doctorate at Imperial College, and he submitted his thesis in August 2007 (one year earlier than he estimated it would take to complete). As well as writing up the previous work he had done, May had to review the work on zodiacal dust undertaken during the intervening 33 years, which included the discovery of the zodiacal dust bands by NASA's IRAS satellite. After a viva voce, the revised thesis (titled "A Survey of Radial Velocities in the Zodiacal Dust Cloud") was approved in September 2007, some 37 years after it had been commenced. He was able to submit his thesis only because of the minimal amount of research on the topic during the intervening years and has described the subject as one that became in-demand again in the 2000s. In his doctoral research, he investigated radial velocity using absorption spectroscopy and doppler spectroscopy of zodiacal light using a Fabry–Pérot interferometer based at the Teide Observatory in Tenerife. His research was initially supervised by Jim Ring, Ken Reay and in the latter stages by Michael Rowan-Robinson. He graduated at the awards ceremony of Imperial College held in the Royal Albert Hall on 14 May 2008.
In October 2007, May was appointed a visiting researcher in Imperial College and he continues his interest in astronomy and involvement with the Imperial Astrophysics Group. He is co-author, with Sir Patrick Moore and Chris Lintott, of Bang! – The Complete History of the Universe and The Cosmic Tourist. May appeared on the 700th episode of The Sky at Night hosted by Sir Patrick Moore, along with Chris Lintott, Jon Culshaw, Professor Brian Cox, and the Astronomer Royal Martin Rees who, on departing the panel, told Brian May, who was joining it, "I don't know a scientist who looks as much like Isaac Newton as you do." May was also a guest on the first episode of the third series of the BBC's Stargazing Live, on 8 January 2013.
On 17 November 2007, May was appointed chancellor of Liverpool John Moores University, and he was installed in 2008 having also been awarded an honorary fellowship from the university for his contribution to astronomy and services to the public understanding of science. He held the post until 2013. Asteroid 52665 Brianmay was named after him on 18 June 2008 on the suggestion of Patrick Moore (probably influenced by the asteroid's provisional designation of 1998 BM$_{30}$).
In 2014, May co-founded Asteroid Day with Apollo 9 astronaut Rusty Schweickart, B612 Foundation COO Danica Remy and German filmmaker Grigorij Richters. Asteroid Day is a global awareness campaign where people from around the world come together to learn about asteroids and what we can do to protect our planet. May was a guest at the 2016 Starmus Festival where he also performed on stage with composer Hans Zimmer. The theme was Beyond The Horizon: A Tribute To Stephen Hawking.
During the New Horizons Pluto flyby NASA press conference held on 17 July 2015 at Johns Hopkins Applied Physics Lab, May was introduced as a science team collaborator. He told the panel "You have inspired the world." From 31 December 2018 until 1 January 2019, May was in attendance at the watch party for the New Horizons flyby of the Kuiper belt object, 486958 Arrokoth, and performed an updated version of his "New Horizons" celebratory song. As part of May's role as a collaborator with NASA's science team on the New Horizons mission, he worked on the first stereoanaglyph based on images of (486958) Arrokoth that were captured by the spacecraft.
In 2019, he was awarded the Lawrence J. Burpee Medal of the Royal Canadian Geographical Society for outstanding contributions to the advancement of geography.
In 2020, he participated in the team that contributed the stereography images of numerical simulations of asteroid disruptions and re-accumulations in a publication in the peer-reviewed journal Nature Communications by Michel, P. et al. (2020) presenting a scenario of formation of the asteroids (101955) Bennu and (162173) Ryugu, visited by NASA OSIRIS-REx and JAXA Hayabusa2 probes, respectively. He was awarded the JAXA Hayabusa2 Honor Award for his contribution by making stereoscopic images of Ryugu.
In 2021, he contributed the stereography images of the structural stability of double asteroid (65803) Didymos, the target of the NASA DART and ESA Hera missions, in a publication in the peer-reviewed journal Icarus by DART and Hera team members. He is also on the advisory board of the NEO-MAPP project (Near-Earth-Object Modelling and Payloads for Protection), funded by the European Union.
In 2022, May was awarded a Doctorate of Science honoris causa by Professor Brad Gibson in the EA Milne Centre for Astrophysics at the University of Hull. Unable to attend in person, he joined the graduation ceremony via video link. At the Starmus IV festival in Yerevan, Armenia in September 2022, May was awarded the Stephen Hawking Medal for Science Communication.
In December 2022 May was made a Knight Bachelor in the 2023 New Year Honours, the first list of King Charles III's reign. In March 2023, May was officially knighted by the King.

## Personal life

From 1976 to 1988, May was married to Christine Mullen. They had three children. They separated in 1988. May met actress Anita Dobson in 1986. She inspired him to write the 1989 hit "I Want It All". They married on 18 November 2000.
He has said in interviews that he had depression in the late 1980s and early 1990s, to the point of contemplating suicide, for reasons having to do with his troubled first marriage, his perceived failure as a husband and father, and the deaths of Mercury and his father Harold.
According to The Sunday Times Rich List of 2019, May is worth £160 million. He has homes in London and Windlesham, Surrey. May's father Harold was a long-time heavy cigarette smoker. As a result, May dislikes smoking, to the point where he was already prohibiting smoking indoors at his concerts before many countries imposed smoking bans.
A vegan since taking part in the 2020 Veganuary challenge, May has stated that meat eating is responsible for the COVID-19 pandemic. May describes himself as "not belonging to an organized religion, but feels there is a god of some kind which we know very little about".
May is a long-term champion of woodland as a haven and "corridor" for wildlife—both in Surrey, where he has a house, and elsewhere. In 2012, he bought land threatened by building development at Bere Regis, Dorset, and, in 2013 and with the enthusiastic support of local villagers, initiated a project to create an area of woodland, now called May's Wood (or "the Brian May Wood"). The wood consists of 157 acres (64 ha), formerly under the plough, planted by May's team of co-workers with 100,000 trees. May's Wood is said to be flourishing.
In 2013, a new species of the genus Heteragrion (Odonata: Zygoptera) from Brazil was named Heteragrion brianmayi—one of four Heteragrion flatwing damselflies named after the bandmates, paying tribute to the 40th anniversary of Queen's founding.
May experienced a small heart attack in May 2020. It required the insertion of three stents into three blocked arteries. May said he had been "very near death". In September 2024, he revealed that he had suffered a minor stroke which rendered him temporarily without use of his left arm, though May noted he was still able to play guitar.

### Activism

Though a Conservative Party voter most of his life, he has stated that their policies on fox hunting and the culling of badgers meant he did not vote for them in the 2010 UK general election.
In 2013, May joined French guitar player Jean-Pierre Danel for a charity Danel launched for the benefit of animal rights in France. The guitarists signed guitars and art photos together, and were joined by Hank Marvin.
Prior to the 2015 general election, it was reported that May was considering standing as an independent Member of Parliament. It was also revealed that May had started a "Common Decency" project "to re-establish common decency in our lives, work and Parliament". May said he wanted to "get rid of the current government" and wished to see a House of Commons containing "individuals voting according to their conscience". May was one of several celebrities who endorsed the parliamentary candidacy of the Green Party's Caroline Lucas at the election. He also endorsed a Conservative Party candidate, Henry Smith, on the grounds of his animal welfare record.
In July 2015, May criticised UK Prime Minister David Cameron for giving Members of Parliament a free vote on amending the ban on fox hunting in England and Wales. During a live television interview, he described the pro-hunting organisation the Countryside Alliance as "a bunch of lying bastards" for their support for a change to the law. The government postponed the vote following the intervention of the Scottish National Party's Westminster MPs, who committed to vote to keep the ban as it existed. May told anti-hunt protesters in a rally outside Parliament that it was "a very, very important day for our democracy" but added "we have not yet won the war, there's no room for complacency".
In June 2017, May endorsed Labour Party leader Jeremy Corbyn in the 2017 general election. May shared an article on Twitter by The Independent headlined "Jeremy Corbyn says Fox hunting is 'barbarity' and pledges to keep it banned" and captioned it: "Well, I guess that just about clinches it !! Anyone see any good reason not to prefer the evidently decent Corbyn over the weak and wobbly Mrs May? Bri".
In October 2018, May said, "I don't like all this separatist stuff and you know this sort of illusion that we can all stand on our own, to me the future lies in co-operation. I get up every day and put my head in my hands about Brexit – I think it's the stupidest thing we ever tried to do." He also said that Prime Minister Theresa May was "driven by vanity and thirst for power".
In the run-up to the 2019 United Kingdom general election May criticised what he saw as the poor conduct of the media and declined to endorse either candidate, stating that he found it "impossible" to vote for either Jeremy Corbyn or Boris Johnson. After the election in which the Conservatives won a majority, May vowed to continue fighting for animal welfare but in an Instagram and blog post he urged his followers to congratulate Johnson and "wish Boris a decent chance to rebuild Britain" before praising reforms to animal welfare laws made by Conservative Party Environment Secretary Michael Gove. In 2021 May criticised Johnson for his response to the COVID-19 pandemic, calling it inadequate.
In the lead up to the 2019 Okinawan referendum on landfill work at Henoko Bay for the expansion of the base in Okinawa, Japan, May advocated voting in opposition to the landfill.

### Animal welfare

In 2010, May formed an animal welfare organisation Save Me (named after the May-written Queen song). It campaigns for the protection of wild animals with a particular emphasis on preventing hunting of foxes and the culling of badgers. May has commented that "to this day, nobody has been able to prove a mechanism for the transfer of bTB from badger to cow" and has suggested that culling badgers has no benefit. The group's primary concern is to ensure that the Hunting Act 2004 and other laws protecting animals are retained in situ.
In an interview in September 2010 with Stephen Sackur for the BBC's HARDtalk program, May said that he would rather be remembered for his animal welfare work than for his music or scientific work. May is supporter of the International Fund for Animal Welfare, the League Against Cruel Sports, PETA UK and the Harper Asprey Wildlife Rescue. In March 2012, May contributed the foreword to a target paper published by the think tank the Bow Group, urging the government to reconsider its plans to cull thousands of badgers to control bovine TB, stating that the findings of Labour's major badger culling trials, several years earlier, show that culling does not work. The paper was authored by Graham Godwin-Pearson with contributions by leading tuberculosis scientists, including Lord Krebs. This prefaced his 2024 documentary, Brian May: The Badgers, the Farmers and Me, the culmination of a four-year investigation into whether badger culling is necessary for bovine TB prevention.
In October 2010, May received an award from the International Fund for Animal Welfare in recognition of his animal welfare work.
In May 2013, May teamed up with actor Brian Blessed and Flash cartoonist Jonti "Weebl" Picking, as well as animal welfare groups including the RSPCA, to form Team Badger, a "coalition of organisations that have teamed up to fight the planned cull of badgers". With Weebl and Blessed, May recorded a single, "Save the Badger Badger Badger"—a mashup of Weebl's viral 2003 Flash cartoon meme, "Badger Badger Badger", and Queen's "Flash", featuring vocals by Blessed. On 1 September 2013, "Save the Badger Badger Badger" charted at No. 79 on the UK Singles Chart, No. 39 on the UK iTunes chart and No. 1 on the iTunes Rock chart. In June 2013 naturalist Sir David Attenborough and rock guitarist Slash joined May to form a supergroup, Artful Badger and Friends, and released a song dedicated to badgers, "Badger Swagger".
May is a former vice-president of the RSPCA. In September 2024, he resigned his position as vice-president after "damning evidence" emerged of animal welfare failings at RSPCA Assured farms.

### Stereophotography

May has had a lifelong interest in collecting Victorian stereophotography. In 2009, with co-author Elena Vidal, he published his second book, A Village Lost and Found, on the work of English stereophotography innovator T. R. Williams. He was awarded The Royal Photographic Society's Saxby Medal in 2012 for achievement in the field of three-dimensional imaging.
May made a significant technical contribution to the book to accompany the exhibition 'Stereoscopic Photographs of Pablo Picasso by Robert Mouzillat', held at the Holburne Museum in Bath, England, from February to June 2014. The book provides photographs of Picasso in his studio, at a bullfight at Arles, and in his garden. May's 3D Owl viewer is used to view the photographs in 3D.
The purchase of his first card in 1973 started May on a lifelong and worldwide search for Les Diableries, which are stereoscopic photographs depicting scenes of daily life in Hell. On 10 October 2013 the book Diableries: Stereoscopic Adventures in Hell by Brian May, Denis Pellerin and Paula Fleming was published.
In 2017, May published Queen in 3-D, chronicling the group's 50-year history. It contains over 300 of his own stereoscopic photos and is the first book about the band published by one of its members. Included with the book is May's patented OWL Stereoscopic Viewer.
In 2021, May was awarded an honorary fellowship and Denis Pellerin was awarded an Honorary Doctor of Literature from the Royal Holloway College, University of London. The conferred degrees recognised their work to preserve Victorian stereoscopy through the London Stereoscopic Company. It recognises their contribution to photography and preservation.

## Portrayal in film

In the 2018 biographical film Bohemian Rhapsody, he was portrayed by Gwilym Lee. May himself served as a creative and musical consultant for the film, and worked especially closely with Lee.
