Rock and roll

Rock and roll emerged as a defined musical style in the United States in the early to mid-1950s. Rock and roll music emerged from the wide variety of musical genres that existed in the United States in the first half of the 20th century among different ethnic and social groups. Each genre developed over time through changing fashion and innovation, and each one exchanged ideas and stylistic elements with all the others.

The greatest contribution came from the musical traditions of America's black population, with an ancient heritage of oral storytelling through music of African origin, usually with strong rhythmic elements, with frequent use of "blue notes" and often using a "call and response" vocal pattern.

In jazz and blues, a **blue note** is a note that—for expressive purposes—is sung or played at a slightly different pitch than standard. Typically the alteration is between a quartertone and a semitone, but this varies depending on the musical context.
African music was modified through the experience of slavery, and through contact with white musical styles such as the folk ballad, and instruments, such as the Spanish guitar. New styles of music emerged among black Americans in the early 20th century in the form of blues, ragtime, jazz, and gospel music. According to the writer Robert Palmer:

> "Rock 'n' roll was an inevitable outgrowth of the social and musical interactions between blacks and whites in the South and Southwest. Its roots are a complex tangle. Bedrock black church music influenced blues, rural blues influenced white folk song and the black popular music of the Northern ghettos, blues and black pop influenced jazz, and so on.  But the single most important process was the influence of black music on white."

## Gospel music

**Gospel music** usually has dominant vocals (often with strong use of harmony) with Christian lyrics. Gospel music can be traced to the early 17th century, with roots in the black oral tradition. Hymns and sacred songs were often repeated in a call and response fashion. Most of the churches relied on hand clapping and foot stomping as rhythmic accompaniment. Most of the singing was done a cappella.

Several attempts have been made to describe the style of late 19th and early 20th century gospel songs in general. Christ-Janer said "the music was tuneful and easy to grasp ... rudimentary harmonies ... use of the chorus ... varied metric schemes ... motor rhythms were characteristic ... The device of letting the lower parts echo rhythmically a motive announced by the sopranos became a mannerism".

Patrick and Sydnor emphasize the notion that gospel music is "sentimental", quoting Sankey as saying, "Before I sing I must feel", and they call attention to the comparison of the original version of Rowley's "I Will Sing the Wondrous Story" with Sankey's version. Gold said, "Essentially the gospel songs are songs of testimony, persuasion, religious exhortation, or warning. Usually the chorus or refrain technique is found."

According to Yale University music professor Willie Ruff, the singing of psalms in Gaelic by Presbyterians of the Scottish Hebrides evolved from "lining out" – where one person sang a solo and others followed – into the call and response of gospel music of the American South. Coming out of the African-American religious experience, American gospel music can be traced to the early 17th century, with foundations in the works of Dr. Isaac Watts and others. Gospel music has roots in the black oral tradition, and typically utilizes a great deal of repetition, which allows those who could not read the opportunity to participate in worship. During this time, hymns and sacred songs were lined and repeated in a call-and-response fashion, and Negro spirituals and work songs emerged. Repetition and "call and response" are accepted elements in African music, designed to achieve an altered state of consciousness sometimes referred to as "trance", and to strengthen communal bonds.

Most of the churches relied on hand-clapping and foot-stomping as rhythmic accompaniment. Guitars and tambourines were sometimes available, but not frequently. Church choirs became a norm only after emancipation. Most of the singing was done a cappella (without music).

Prior to the meeting of Moody and Sankey in 1870, there was an American rural/frontier history of revival and camp meeting songs, but the gospel hymn was of a different character, and it served the needs of mass revivals in the great cities.

The holiness-Pentecostal movement, or sanctified movement, appealed to people who were not attuned to the Europeanized version of black church music. Holiness worship has used any type of instrumentation that congregation members might bring in, from tambourines to electric guitars. Pentecostal churches readily adopted and contributed to the gospel music publications of the early 20th century. Sister Rosetta Tharpe was the first great recording star of gospel music. Late 20th-century musicians such as Elvis Presley, Jerry Lee Lewis, Mahalia Jackson, Andrae Crouch, and the Blackwood Brothers either were raised in a Pentecostal environment, or have acknowledged the influence of that tradition.

The Pentecostal movement, especially in its early stages, was typically associated with the impoverished and marginalized of America, especially African Americans and Southern Whites. With the help of many healing evangelists such as Oral Roberts, Pentecostalism spread across America by the 1950s

## Blues

Little is known about the exact origin of the music now known as the blues. No specific year can be cited as the origin of the blues, largely because the style evolved over a long period and existed in approaching its modern form before the term *blues* was introduced and before the style was thoroughly documented. Ethnomusicologist Gerhard Kubik traces the roots of many of the elements that were to develop into the blues back to the African continent, the "cradle of the blues". One important early mention of something closely resembling the blues comes from 1901, when an archaeologist in Mississippi described the songs of black workers which had lyrical themes and technical elements in common with the blues.

**Blues** is a music genre and musical form which was originated in the Deep South of the United States around the 1870s by African-Americans from roots in African musical traditions, African-American work songs, and spirituals. Blues incorporated spirituals, work songs, field hollers, shouts, chants, and rhymed simple narrative ballads. The blues form, ubiquitous in jazz, rhythm and blues and rock and roll, is characterized by the call-and-response pattern, the blues scale and specific chord progressions, of which the twelve-bar blues is the most common. Blue notes (or "worried notes"), usually thirds, fifths or sevenths flattened in pitch are also an essential part of the sound. Blues shuffles or walking bass reinforce the trance-like rhythm and form a repetitive effect known as the groove.

Blues as a genre is also characterized by its lyrics, bass lines, and instrumentation. Early traditional blues verses consisted of a single line repeated four times. It was only in the first decades of the 20th century that the most common current structure became standard: the AAB pattern, consisting of a line sung over the four first bars, its repetition over the next four, and then a longer concluding line over the last bars. Early blues frequently took the form of a loose narrative, often relating the racial discrimination and other challenges experienced by African-Americans.

Many elements, such as the call-and-response format and the use of blue notes, can be traced back to the music of Africa. The origins of the blues are also closely related to the religious music of the Afro-American community, the spirituals. The first appearance of the blues is often dated to after the ending of slavery and, later, the development of juke joints. It is associated with the newly acquired freedom of the former slaves. Chroniclers began to report about blues music at the dawn of the 20th century. The first publication of blues sheet music was in 1908. Blues has since evolved from unaccompanied vocal music and oral traditions of slaves into a wide variety of styles and subgenres. Blues subgenres include country blues, such as Delta blues and Piedmont blues, as well as urban blues styles such as Chicago blues and West Coast blues. World War II marked the transition from acoustic to electric blues and the progressive opening of blues music to a wider audience, especially white listeners. In the 1960s and 1970s, a hybrid form called blues rock developed, which blended blues styles with rock music.

### Ragtime

**Ragtime** – also spelled **rag-time** or **rag time** – is a musical style that enjoyed its peak popularity between 1895 and 1919. Its cardinal trait is its syncopated or "ragged" rhythm.

The style has its origins in African-American communities in cities such as St. Louis.

Ragtime originated in African American music in the late 19th century and descended from the jigs and march music played by African American bands, referred to as "jig piano" or "piano thumping".

By the start of the 20th century, it became widely popular throughout North America and was listened and danced to, performed, and written by people of many different subcultures. A distinctly American musical style, ragtime may be considered a synthesis of African syncopation and European classical music, especially the marches made popular by John Philip Sousa.

Some early piano rags are entitled marches, and "jig" and "rag" were used interchangeably in the mid-1890s. Ragtime was also preceded by its close relative the cakewalk. In 1895, black entertainer Ernest Hogan composed two of the earliest sheet music rags, one of which ("All Coons Look Alike to Me") eventually sold a million copies. The other composition was called "La Pas Ma La", and it was also a hit.

As black musician Tom Fletcher said, Hogan was the "first to put on paper the kind of rhythm that was being played by non-reading musicians." While the song's success helped introduce the country to ragtime rhythms, its use of racial slurs created a number of derogatory imitation tunes, known as "coon songs" because of their use of racist and stereotypical images of blacks. In Hogan's later years, he admitted shame and a sense of "race betrayal" from the song, while also expressing pride in helping bring ragtime to a larger audience.

### Boogie-woogie

**Boogie-woogie** is a music genre that became popular during the late 1920s, developed in African-American communities in the 1870s. It was eventually extended from piano, to piano duo and trio, guitar, big band, country and western music, and gospel. While the blues traditionally expresses a variety of emotions, boogie-woogie is mainly associated with dancing. The lyrics of one of the earliest hits, "Pinetop's Boogie Woogie", consist entirely of instructions to dancers:

>
> Now, when I tell you to hold yourself, don't you move a peg.
>
> And when I tell you to get it, I want you to Boogie Woogie!
>

## Jazz

**Jazz** is a music genre that originated in the African-American communities of New Orleans, United States. It originated in the late 19th and early 20th centuries, and developed from roots in blues and ragtime. Jazz is seen by many as "America's classical music". Since the 1920s Jazz Age, jazz has become recognized as a major form of musical expression. It then emerged in the form of independent traditional and popular musical styles, all linked by the common bonds of African-American and European-American musical parentage with a performance orientation. Jazz is characterized by swing and blue notes, call and response vocals, polyrhythms and improvisation. Jazz has roots in West African cultural and musical expression, and in African-American music traditions including blues and ragtime, as well as European military band music. Intellectuals around the world have hailed jazz as "one of America's original art forms".

As jazz spread around the world, it drew on national, regional, and local musical cultures, which gave rise to different styles. New Orleans jazz began in the early 1910s, combining earlier brass-band marches, French quadrilles, biguine, ragtime and blues with collective polyphonic improvisation. In the 1930s, heavily arranged dance-oriented swing big bands, Kansas City jazz, a hard-swinging, bluesy, improvisational style and Gypsy jazz (a style that emphasized musette waltzes) were the prominent styles. Bebop emerged in the 1940s, shifting jazz from danceable popular music toward a more challenging "musician's music" which was played at faster tempos and used more chord-based improvisation. Cool jazz developed near the end of the 1940s, introducing calmer, smoother sounds and long, linear melodic lines.

The 1950s saw the emergence of free jazz, which explored playing without regular meter, beat and formal structures, and in the mid-1950s, hard bop emerged, which introduced influences from rhythm and blues, gospel, and blues, especially in the saxophone and piano playing. Modal jazz developed in the late 1950s, using the mode, or musical scale, as the basis of musical structure and improvisation. Jazz-rock fusion appeared in the late 1960s and early 1970s, combining jazz improvisation with rock music's rhythms, electric instruments, and highly amplified stage sound. In the early 1980s, a commercial form of jazz fusion called smooth jazz became successful, garnering significant radio airplay. Other styles and genres abound in the 2000s, such as Latin and Afro-Cuban jazz.

### Swing music

**Swing music**, or simply **swing**, is a form of popular jazz music developed in the United States that dominated in the 1930s and 1940s. The name swing came from the 'swing feel' where the emphasis is on the off–beat or weaker pulse in the music. Swing bands usually featured soloists who would improvise on the melody over the arrangement. The danceable swing style of big bands and bandleaders such as Benny Goodman was the dominant form of American popular music from 1935 to 1946, a period known as the swing era. The verb "to swing" is also used as a term of praise for playing that has a strong groove or drive. Notable musicians of the swing era include Louis Armstrong, Louis Prima, Larry Clinton, Duke Ellington, Count Basie, Benny Goodman, Artie Shaw, Glenn Miller, Woody Herman, Tommy Dorsey, Jimmy Dorsey, Harry James, Louis Jordan, and Cab Calloway.

Swing has roots in the 1920s as larger dance music ensembles began using new styles of written arrangements incorporating rhythmic innovations pioneered by Louis Armstrong and Earl Hines. A typical song played in swing style would feature a strong, anchoring rhythm section in support of more loosely tied wind and brass. The most common style consisted of theme choruses and choruses with improvised solos within the framework of his bandmates playing support. Swing music began to decline in popularity during World War II because of several factors. Swing influenced the later styles of traditional pop music, jump blues, and bebop jazz. Swing music saw a revival in the late 1950s and 1960s with the resurgent Count Basie and Duke Ellington orchestras, and with pop vocalists such as Frank Sinatra and Nat King Cole.

Swing blended with other genres to create new music styles. In country music, artists such as Jimmie Rodgers, Moon Mullican and Bob Wills introduced many elements of swing along with blues to create a genre called western swing. Gypsy swing is an outgrowth of Venuti and Lang's jazz violin swing. Swing revivals have occurred periodically from the late 1960s to the 2000s. In the late-1980s (into the early 1990s) a trendier, more urban-styled swing-beat emerged called new jack swing, spearheaded by Teddy Riley. In the late 1990s and into the 2000s there was a swing revival, led by Squirrel Nut Zippers, Brian Setzer, Big Bad Voodoo Daddy, and Lavay Smith. In Canada, some of the early 2000s records by The JW-Jones Blues Band included swing revival elements.

## Rock and roll

By the 1930s, African American musicians, such as Cab Calloway, Fletcher Henderson and Duke Ellington, were developing swing music, essentially jazz played for dancing, and in some areas such as New York City processes of social integration were taking place. According to Palmer, by the mid-1930s, elements of rock and roll could be found in every type of American folk and blues music. Some jazz bands, such as Count Basie's, increasingly played rhythmic music that was heavily based on blues riffs. In Chicago, blues performers formed into small groups, such as the Harlem Hamfats, and explored the use of amplification. In the Midwest, jump bands developed instrumental blues based on riffs, with saxophone solos and shouted vocals. In Nashville and elsewhere, country music played by white musicians such as Jimmie Rodgers incorporated blues styles, and in some cases was recorded with (uncredited) black musicians. In Texas and Oklahoma, Western swing bands, such as Bob Wills, combined elements of big band, blues and country music into a new style of dance music. As musicians from different areas and cultures heard each other's music, so styles merged and innovations spread. Increasingly, processes of active cross-fertilisation took place between the music played and heard by white people and the music predominantly played and heard by black people. These processes of exchange and mixing were fueled by the spread of radio, 78 rpm and later records and jukeboxes, and the expansion of the commercial popular music business. The music also benefited from the development of new amplification and electronic recording techniques from the 1930s onward, including the invention of the electric guitar, first recorded as a virtuoso instrument by Charlie Christian.

In 1938, promoter and record producer John H. Hammond staged the first "From Spirituals to Swing" concert in New York City to highlight black musical styles. It featured pianist Pete Johnson and singer Big Joe Turner, whose recording of "Roll 'Em Pete" helped spark a craze across American society for "boogie woogie" music, mostly played by black musicians. In both musical and social terms, this helped pave the way for rock and roll music. Economic changes also made the earlier big bands unwieldy; Louis Jordan left Chick Webb's orchestra the same year to form the Tympany Five. Mixing of genres continued through the shared experiences of the World War II, and afterward a new style of music emerged, featuring "honking" saxophone solos, increasing use of the electric guitar, and strongly accented boogie rhythms. This "jump blues" encompassed both novelty records, such as those by Jordan, and more heavily rhythmic recordings such as those by Lionel Hampton.

Increasingly, the term "rocking" was used in the records themselves, and by the late 1940s frequently was used to describe the music of performers such as Wynonie Harris whose records reached the top of the newly christened "rhythm and blues" charts.

In 1947, blues singer Roy Brown recorded "Good Rocking Tonight", a song that parodied church music by appropriating its references, including the word "rocking" and the gospel call "Have you heard the news?", relating them to very worldly lyrics about dancing, drinking and sex. The song became much more successful the following year when recorded by Wynonie Harris, whose version changed the steady blues rhythm to an uptempo gospel beat, and it was re-recorded by Elvis Presley in 1954 as his second single. A craze began in the rhythm and blues market for songs about "rocking", including "We're Gonna Rock" by Wild Bill Moore, the first commercially successful "honking" sax record, with the words "We're gonna rock, we're gonna roll" as a background chant. One of the most popular was "Rock the Joint", first recorded by Jimmy Preston in May 1949, and a R&B top 10 hit that year. Preston's version is often considered a prototype of a rock-and-roll song, and it was covered in 1952 by Bill Haley and the Saddlemen. Marshall Lytle, Haley's bass player, claimed that this was one of the songs that inspired Alan Freed to coin the phrase "rock and roll" to refer to the music he played.

Freed first started playing the music in 1951, and by 1953 the phrase "rock and roll" was becoming used much more widely to market the music beyond its initial black audience. The practitioners of the music were young black artists, appealing to the post-war community's need for excitement, dancing and increasing social freedoms, but the music also became very attractive to white teenagers. As well as "rocking" rhythm and blues songs, such as the massively successful and influential "Rocket 88" recorded by Ike Turner and his band but credited to singer Jackie Brenston, the term was used to encompass other forms of black music. In particular, vocal harmony group recordings in the style that later became known as "doo-wop", such as "Gee" by the Crows and "Earth Angel" by the Penguins, became huge commercial successes, often for the new small independent record companies becoming established. These included Modern, Imperial, Specialty, Atlantic, King and Chess.

The adoption of rock and roll by white people was hindered by racist attitudes. As Billy Burnette said about his father Dorsey Burnette and uncle Johnny Burnette:

> They'd buy their clothes on Beale Street, at Lansky Brothers, where all the black people shopped. Right outside Memphis, there was a voodoo village, all black-real mystic kind of people... A lot of real old line southern people called my dad and my uncle white ni\*\*er. Nobody was doing rock-and-roll in those days except people they called white trash. When my dad and my uncle started doin' it, they were just about the first.

Although some of the rhythm and blues musicians who had been successful in earlier years – such as Joe Turner, Ruth Brown, and Fats Domino who had his first R&B hit in 1950 – made the transition into new markets, much of the initial breakthrough into the wider pop music market came from white musicians, such as Haley, Presley, Carl Perkins and Jerry Lee Lewis, re-recording earlier rhythm and blues hits, often making use of technological improvements in recording and innovations such as double tracking, developed by the large mainstream record companies, as well as the invention of the 45-rpm record and the rapid growth of its use in jukeboxes. At the same time, younger black musicians such as Little Richard, Chuck Berry and Bo Diddley took advantage of the gradual breakdown of ethnic barriers in America to become equally popular and help launch the rock and roll era. By the time of Haley's first hits in 1953, and those of Berry, Little Richard and then Presley the next year, rock and roll was firmly established.
The Pentecostal church has also been identified as a crucial component in the development of rock and roll. The modern Pentecostal movement parallels rock and roll in many ways. Further, the unhinged, wild energy of the church is evidenced in the most important of early rock performers that were also raised in Pentecostal churches, including Sister Rosetta Tharpe, Elvis Presley, Little Richard, and Jerry Lee Lewis.

## Disco

**Disco** is a genre of dance music and a subculture that emerged in the 1970s from the United States' urban nightlife scene.

The disco sound is typified by "four-on-the-floor" beats, syncopated basslines, and string sections, horns, electric piano, synthesizers, and electric rhythm guitars. Lead guitar features less frequently in disco than in rock. Well-known disco artists include Donna Summer, Gloria Gaynor, the Bee Gees, Chic, KC and the Sunshine Band, Thelma Houston, Sister Sledge, Cerrone, Village People and Michael Jackson. While performers and singers garnered public attention, record producers working behind the scenes played an important role in developing the genre. Films such as *Saturday Night Fever* (1977) and *Thank God It's Friday* (1978) contributed to disco's mainstream popularity.

Disco started as a mixture of music from venues popular with African Americans, Hispanic and Latino Americans, Italian Americans, LGBT people (especially African-American, Latino-American, and Italian-American gay men), and psychedelic hippies in Philadelphia and New York City during the late 1960s and early 1970s. Disco can be seen as a reaction by the counterculture during this period to both the dominance of rock music and the stigmatization of dance music at the time. Several dance styles were developed during the period of disco's popularity in the United States, including “the Bump” and “the Hustle”.

By the late ‘70s, most major U.S. cities had thriving disco club scenes, and DJs would mix dance records at clubs such as Studio 54 in New York City, a venue popular among celebrities. Discothèque-goers often wore expensive, extravagant and sexy fashions. There was also a thriving drug subculture in the disco scene, particularly for drugs that would enhance the experience of dancing to the loud music and the flashing lights, such as cocaine and Quaaludes, the latter being so common in disco subculture that they were nicknamed "disco biscuits". Disco clubs were also associated with promiscuity as a reflection of the sexual revolution of this era in popular history.

Disco was the last popular music movement driven by the baby boom generation. It began to decline in the United States during 1979-80, and by 1982 it had lost nearly all popularity there. Disco Demolition Night, an anti-disco protest held in Chicago on July 12, 1979, remains the most well-known of several "backlash" incidents across the country that symbolized disco's declining fortune.

Disco was a key influence in the development of electronic dance music and house music. It has had several revivals, such as Madonna's highly successful 2005 album *Confessions on a Dance Floor*, and more recently in the 2010s, entering the pop charts in the US and the UK.
