rock music

The tradition & historical record

Rock music is a genre of popular music that originated in the United States as "rock and roll" in the late 1940s and early 1950s, developing into a range of styles from the late 50s to mid-1960s, primarily in the United States and United Kingdom. It has its roots beginning as classic rock and roll, a style that drew from the African-American musical genres of blues and rhythm and blues, as well as from country music. Rock also drew strongly from genres such as electric blues and folk, and incorporated influences from jazz and other styles. Rock is typically centered on the electric guitar, usually as part of a rock group with an electric bass guitar, drums, and one or more singers. Usually, rock is song-based music with a 44 time signature and using a verse–chorus form; however, the genre has become extremely diverse. Like pop music, lyrics often stress romantic love but also address a wide variety of other themes that are frequently social or political. Rock was the most popular genre of music in the U.S. and much of the western world from the 1960s up to the 2010s. Rock musicians in the mid-1960s began to advance the album ahead of the single as the dominant form of recorded music expression and consumption, with the Beatles at the forefront of this development. Their contributions lent the genre a cultural legitimacy in the mainstream and initiated a rock-informed album era in the music industry for the next several decades. ¹

The sound of rock is traditionally centered on the amplified electric guitar, which emerged in its modern form in the 1950s with the popularity of rock and roll. It was also greatly influenced by the sounds of electric blues guitarists. The sound of an electric guitar in rock music is typically supported by an electric bass guitar, which pioneered jazz music in the same era, and by percussion produced from a drum kit that combines drums and cymbals. This trio of instruments has often been complemented by the inclusion of other instruments, particularly keyboards such as the piano, the Hammond organ, and the synthesizer. The basic rock instrumentation was derived from the basic electric blues band instrumentation (prominent lead guitar, second chordal instrument, bass, and drums). A group of musicians performing rock music is termed as a rock band or a rock group. It typically consists of between three (the power trio) and five members. Classically, a rock band takes the form of a quartet whose members cover one or more roles, including vocalist, lead guitarist, rhythm guitarist, bass guitarist, drummer, and often keyboard player or another instrumentalist. ¹

Rock music is traditionally built on a foundation of simple syncopated rhythms in a 44 meter, with a repetitive snare drum back beat on beats two and four. Melodies often originate from older musical modes such as the Dorian and Mixolydian, as well as the major and minor scales. Harmonies range from the common triad to parallel perfect fourths and fifths and dissonant harmonic progressions. Since the late 1950s, and particularly from the mid-1960s onwards, rock music often used the verse–refrain structure derived from blues and folk music, but there has been considerable variation from this model. ¹

The foundations of rock music are in rock and roll, which originated in the United States during the late 1940s and early 1950s; the genre spread to much of the rest of the world. Its origins lay in a melding of various black musical genres of the time, including rhythm and blues and gospel music, with country and western. ¹

Debate surrounds the many recordings which have been suggested as "the first rock and roll record". Contenders include "Strange Things Happening Every Day" by Sister Rosetta Tharpe (1944); "That's All Right" by Arthur Crudup (1946), which was later covered by Elvis Presley in 1954; "The House of Blue Lights" by Ella Mae Morse and Freddie Slack (1946); Wynonie Harris' "Good Rocking Tonight" (1948); Goree Carter's "Rock Awhile" (1949); Jimmy Preston's "Rock the Joint" (1949), also covered by Bill Haley & His Comets in 1952; and "Rocket 88" by Jackie Brenston and his Delta Cats (in fact, Ike Turner and his band the Kings of Rhythm), recorded by Sam Phillips for Chess Records in 1951. In 1951, Cleveland, Ohio, disc jockey Alan Freed began playing rhythm and blues music (then termed "race music") for a multi-racial audience, and is credited with first using the phrase "rock and roll" to describe the music. Four years later, Bill Haley's "Rock Around the Clock" (1954) became the first rock and roll song to top Billboard magazine's main sales and airplay charts, and opened the door worldwide for this new wave of popular culture. Other artists with early rock and roll hits included Chuck Berry, Bo Diddley, Fats Domino, Little Richard, Jerry Lee Lewis, and Gene Vincent. ¹

Rock quickly spread out from its origins in the US, associated with the rapid Americanization that was taking place globally in the aftermath of the Second World War. Cliff Richard is credited with one of the first rock and roll hits outside of North America with "Move It" (1959), effectively ushering in the sound of British rock. Several artists, most prominently Tommy Steele from the UK, found success with covers of major American rock and roll hits before the recordings could spread internationally, often translating them into local languages where appropriate. Steele in particular toured Britain, Scandinavia, Australia, the USSR and South Africa from 1955 to 1957, influencing the globalisation of rock. Johnny O'Keefe's 1958 record "Wild One" was one of the earliest Australian rock and roll hits. By the late 1950s, as well as in the American-influenced Western world, rock was popular in communist states such as Yugoslavia, and the USSR, as well as in regions such as South America. In the late 1950s and early 1960s, U.S. blues music and blues rock artists, who had been surpassed by the rise of rock and roll in the US, found new popularity in the UK, visiting with successful tours. Lonnie Donegan's 1955 hit "Rock Island Line" was a major influence and helped to develop the trend of skiffle music groups throughout the country, many of which, including John Lennon's Quarrymen (later the Beatles), moved on to play rock and roll. ¹

The first four years of the 1960s have often been seen as an era of hiatus for rock and roll. However, some authors have emphasised innovations and trends in this period without which future developments would not have been possible. While early rock and roll, particularly through the advent of rockabilly, saw the greatest commercial success for male and white performers, in this era the genre was dominated by black and female artists. Rock and roll had not disappeared entirely from music at the end of the 1950s and some of its energy can be seen in the various dance crazes of the early 1960s, started by Chubby Checker's record "The Twist" (1960). ¹
