Rock music is a genre of popular music that entered the mainstream in the 1960s. It has its roots in 1940s and 1950s rock and roll, rhythm and blues, country music and also drew on folk music, jazz and classical music.
The sound of rock often revolves around the guitar and it uses a strong back beat laid down by a rhythm section of electric bass guitar, drums, and keyboard instruments such as organ, piano, or, since the 1970s, synthesizers. Along with the guitar or keyboards, saxophone and blues-style harmonica are sometimes used as soloing instruments. In its "purest form", it "has three chords, a strong, insistent back beat, and a catchy melody."
In the late 1960s and early 1970s, rock music developed different subgenres. When it was blended with folk music it created folk rock, with blues to create blues-rock and with jazz, to create jazz-rock fusion. In the 1970s, rock incorporated influences from soul, funk, and Latin music. Also in the 1970s, rock developed a number of subgenres, such as soft rock, glam rock, heavy metal, hard rock, progressive rock, and punk rock. Rock subgenres that emerged in the 1980s included new wave, hardcore punk and alternative rock. In the 1990s, rock subgenres included grunge, Britpop, indie rock, and nu metal.
A group of musicians specializing in rock music is called a rock band or rock group. Many rock groups consist of an electric guitarist, lead singer, bass guitarist, and a drummer, forming a quartet. Some groups omit one or more of these roles and/or utilize a lead singer who plays an instrument while singing, sometimes forming a trio or duo; others include additional musicians such as one or two rhythm guitarists and/or a keyboardist. More rarely, groups also utilize stringed instruments such as violins or cellos, woodwind instruments such as saxophones, and brass instruments such as trumpets or trombones.
Rock and roll evolved in the United States in the late 1940s and early 1950s, and quickly spread to much of the rest of the world. Its immediate origins lay in a mixing together of various popular musical genres of the time, including rhythm and blues, gospel music, and country and western. In 1951, Cleveland, Ohio disc jockey Alan Freed began playing rhythm and blues music for a multi-racial audience, and is credited with first using the phrase "rock and roll" to describe the music.
There is much debate as to what should be considered the first rock & roll record. One leading contender is "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 Sun Records in 1951. Four years later, Bill Haley's "Rock Around the Clock" (1955) 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.
Rolling Stone magazine argued in 2004 that "That's All Right (Mama)" (1954), Elvis Presley's first single for Sun Records in Memphis, was the first rock and roll record. But, at the same time, Big Joe Turner's "Shake, Rattle & Roll", later covered by Haley, was already at the top of the Billboard R&B charts. Other artists with early rock and roll hits included Chuck Berry, Bo Diddley, Fats Domino, Little Richard, Jerry Lee Lewis, and Gene Vincent.
The 1950s saw the growth in popularity of the electric guitar, and the development of a specifically rock and roll style of playing through such exponents as Berry, Link Wray, and Scotty Moore. It also saw major developments in recording technology such as multitrack recording developed by Les Paul, the electronic treatment of sound by such innovators as Joe Meek, and the Wall of Sound productions of Phil Spector. All these developments were important influences on later rock music.
The social effects of rock and roll were worldwide and massive. Far beyond simply a musical style, rock and roll influenced lifestyles, fashion, attitudes, and language.[8] In addition, rock and roll may have helped the cause of the civil rights movement because both African American teens and white American teens enjoyed the music. Motown played an important role in the racial integration of popular music, as it was the first record label owned by an African American to primarily feature African-American artists who achieved crossover success. In the early 1960s, Motown and its soul-based subsidiaries were the most successful proponents of what came to be known as The Motown Sound, a style of soul music with a distinct pop influence. From 1961 to 1971, Motown had 110 top 10 hits, and artists such as Stevie Wonder, Marvin Gaye, The Supremes, The Four Tops, and The Jackson 5, were all signed to Motown labels. All of these acts have been inducted into the Rock and Roll Hall of Fame.
The instrumental rock and roll pioneered by performers such as Duane Eddy, Link Wray, and The Ventures was developed by Dick Dale who added distinctive "wet" reverb, rapid alternate picking, as well as Middle Eastern and Mexican influences, producing the regional hit "Let's Go Trippin'" in 1961 and launching the surf music craze. Like Dale and his Del-Tones, most early surf bands were formed in Southern California, including the Bel-Airs, the Challengers, and Eddie & the Showmen. The Chantays scored a top ten national hit with "Pipeline" in 1963 and probably the single most famous surf tune hit was 1963's "Wipe Out", by the Surfaris, which hit # 2 and # 10 on the Billboard charts in 1965.
The growing popularity of the genre led groups from other areas to try their hand. These included The Astronauts, from Boulder, Colorado, The Trashmen, from Minneapolis, Minnesota, who had a number 4 hit with "Surfin Bird" in 1964 and The Rivieras from South Bend, Indiana, who reached #5 in 1964 with "California Sun".[12] The Atlantics, from Sydney, Australia, made a significant contribution to the genre, with their hit "Bombora" (1963). European instrumental bands around this time generally focused more on the more rock and roll style played by The Shadows, but The Dakotas, who were the British backing band for Merseybeat singer Billy J. Kramer, gained some attention as surf musicians with "Cruel Sea" (1963), which was later covered by American instrumental surf bands, including The Ventures.
Surf music achieved its greatest commercial success as vocal music, particularly the work of the Beach Boys, formed in 1961 in Southern California. Their early albums included both instrumental surf rock (among them covers of music by Dick Dale) and vocal songs, drawing on rock and roll and doo wop and the close harmonies of vocal pop acts like the Four Freshmen. Their first chart hit, "Surfin'" in 1962 reached the Billboard top 100 and helped make the surf music craze a national phenomenon. From 1963 the group began to leave surfing behind as subject matter as Brian Wilson became their major composer and producer, moving on to the more general themes of male adolescence including cars and girl in songs like "Fun, Fun, Fun" (1964) and "California Girls" (1965).
Other vocal surf acts followed, including one-hit wonders like Ronny & the Daytonas with "G. T. O." (1964) and Rip Chords with "Hey Little Cobra", which both reached the top ten, but the only other act to achieve sustained success with the formula were Jan & Dean, who had a number 1 hit with "Surf City" (co-written with Brian Wilson) in 1963. The surf music craze and the careers of almost all surf acts, was effectively ended by the arrival of the British Invasion from 1964. Only the Beach Boys were able to sustain a creative career into the mid-1960s, producing a string of hit singles and albums, including the highly Pet Sounds in 1966, which made them, arguably, the only American rock or pop act that could rival the Beatles.
