full_context: Document 1: Music Man Bongo: The Bongo is a model of bass guitar manufactured by Music Man, a division of Ernie Ball. It was first introduced at the NAMM Show on March 21, 2003. Ernie Ball president Sterling Ball designed the instrument in conjunction with the Music Man Research and Development department and BMW's Designworks team. It is equipped with an 18-volt 4-band preamp (except on the single-pickup model, which has a 3-band preamp; single-pickup models with piezo bridges have a 4-band preamp) designed by Dudley Gimpel with help from Cliff Hugo and other Music Man artists. It also sports a sleek, carved basswood body with high-gloss polyester finish and a satin-finish painted 34" scale maple neck with rosewood fingerboard (pau ferro on lined or unlined fretless, ebony on both fretted and fretless "stealth" basses) featuring 24 high-profile wide frets and crescent moon-shaped position inlays. These basses are generally known for their dual humbucking pickup configuration, as they are the first twin humbucker-equipped models released by Music Man since the introduction of their Sabre and Cutlass bass guitars in the late 1970s.

Document 4: Mandolin: Another family of bowlback mandolins came from Milan and Lombardy. These mandolins are closer to the mandolino or mandore than other modern mandolins. They are shorter and wider than the standard Neapolitan mandolin, with a shallow back. The instruments have 6 strings, 3 wire treble-strings and 3 gut or wire-wrapped-silk bass-strings. The strings ran between the tuning pegs and a bridge that was glued to the soundboard, as a guitar's. The Lombardic mandolins were tuned g b e' a' d" g". A developer of the Milanese stye was Antonio Monzino (Milan) and his family who made them for 6 generations.
Document 5: The Graham Bond Organisation: The Graham Bond Organisation were a British jazz/rhythm and blues group of the early 1960s consisting of Graham Bond (vocals, keyboards, alto-saxophone), Jack Bruce (bass), Ginger Baker (drums), Dick Heckstall-Smith (tenor/soprano saxophone) and John McLaughlin (guitar). They recorded several albums and further recordings were issued when the group's members achieved fame in progressive rock and jazz fusion. The spelling of the band's original name varied between releases, often depending on the intended audience. The British English spelled as "Organisation" or "ORGANisation" (Bond's original plan), while in some other countries outside the UK spelled "Organization".
Document 6: Emerson, Lake & Palmer: Emerson, Lake & Palmer (ELP) were an English progressive rock supergroup formed in London in 1970. The band consisted of keyboardist Keith Emerson, singer, bassist and producer Greg Lake and drummer and percussionist Carl Palmer. With nine RIAA - certified gold record albums in the US, and an estimated 48 million records sold worldwide, they were one of the most popular and commercially successful progressive rock bands in the 1970s, with a musical sound including adaptations of classical music with jazz and symphonic rock elements, dominated by Emerson's flamboyant use of the Hammond organ, Moog synthesizer, and piano (although Lake wrote several acoustic songs for the group).
Document 7: Trefor Goronwy: Trefor Goronwy is a vocalist, bass guitarist, guitarist, and percussionist. He joined This Heat for their final European tour in 1982, and continued to work with drummer Charles Hayward and soundman Stephen Rickard in the group Camberwell Now. He has also worked as a sound technician with groups such as Pere Ubu, Towering Inferno, David Thomas and Two Pale Boys, Spearmint, Momus and the Tuvan throat-singing ensemble Huun-Huur-Tu, whose first album he recorded in London.

Document 8: No More Lonely Nights: Paul McCartney -- lead vocal, piano Linda McCartney -- backing vocal, keyboards Eric Stewart -- backing vocal David Gilmour -- guitar solo Herbie Flowers -- bass Anne Dudley -- synthesiser Stuart Elliott -- drums
Document 9: Bee Gees: When it, too, failed to attract much interest, Mardin encouraged them to work within the soul music style. The brothers attempted to assemble a live stage band that could replicate their studio sound. Lead guitarist Alan Kendall had come on board in 1971 but did not have much to do until Mr. Natural. For that album, they added drummer Dennis Bryon, and they later added ex-Strawbs keyboard player Blue Weaver, completing the Bee Gees band that lasted through the late '70s. Maurice, who had previously performed on piano, guitar, harpsichord, electric piano, organ, mellotron and bass guitar, as well as mandolin and Moog synthesiser, by then confined himself to bass onstage.
Document 10: Höfner 500/1: The Höfner 500/1 violin bass (nicknamed the "Beatle bass" or "Cavern bass") is a hollow-bodied bass guitar manufactured by Höfner under several varieties. It was introduced in the mid-1950s and gained celebrity status during the 1960s as one of the primary basses used by Paul McCartney of The Beatles.
Document 11: Ned Steinberger: Ned Steinberger (b. Princeton, New Jersey, 1948) is an American creator of innovative musical instruments. He is most notable for his design of guitars and basses without a traditional headstock, which are called Steinberger instruments. He also has a line of electric basses and string instruments through his company called NS Design and was also the designer of the first ever Spector bass, the NS. In addition, Ned and Emmett Chapman, creator of the Chapman Stick, collaborated on the creation of the NS Stick, a guitar/bass "multi-mode" instrument sold by Stick Enterprises.
Document 12: The Battle of Evermore: "The Battle of Evermore" is a folk duet sung by Robert Plant and Sandy Denny, featured on Led Zeppelin's untitled 1971 album, commonly known as "Led Zeppelin IV". The song's instrumentation features acoustic guitar and mandolin playing.
Document 13: Bass guitar: In the 1930s, musician and inventor Paul Tutmarc from Seattle, Washington, who was manufacturing lap steel guitars, developed the first electric string bass in its modern form, a fretted instrument designed to be played horizontally. The 1935 sales catalog for Tutmarc's electronic musical instrument company, Audiovox, featured his ``Model 736 Bass Fiddle '', a four - stringed, solid - bodied, fretted electric bass instrument with a 30 ⁄ - inch (775 - millimetre) scale length. The adoption of a guitar's body shape made the instrument easier to hold and transport than any of the existing stringed bass instruments. The addition of frets enabled bassists to play in tune more easily than on fretless acoustic or electric upright basses. Around 100 of these instruments were made during this period.
Document 14: Solid body: The origins of the solid body electric guitar are confusing. The first commercially available solid body electric Spanish guitar was produced by the Rickenbacker company in 1931. Les Paul, a guitarist, is often erroneously credited with inventing the first solid body, but Fender is often incorrectly credited as the first to commercially market a solid body electric guitar, which itself was based on a design by Merle Travis. Also it is reported that around the same time (1940) a solid body was created by Jamaican musician and inventor, Hedley Jones. In the 1940s, Les Paul created a guitar called the ``Log, ''which came`` from the 4'' by 4 ''solid block of pine which the guitarist had inserted between the sawed halves of the body that he'd just dismembered. He then carefully re-joined the neck to the pine log, using some metal brackets.'' He then put some pickups that he designed on it. He soon went to companies asking if they would buy his guitar. They turned him down. However, after the Fender Telecaster electric guitar became popular, the Gibson company contacted him and had him endorse a model named after him, The Les Paul guitar. It came out in 1952.
Document 15: Mandolin: The instrument was primarily used in an ensemble setting well into the 1930s, and although the fad died out at the beginning of the 1930s, the instruments that were developed for the orchestra found a new home in bluegrass. The famous Lloyd Loar Master Model from Gibson (1923) was designed to boost the flagging interest in mandolin ensembles, with little success. However, The "Loar" became the defining instrument of bluegrass music when Bill Monroe purchased F-5 S/N 73987 in a Florida barbershop in 1943 and popularized it as his main instrument.
