Rock music
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 mid-1960s, primarily in the United States and United Kingdom. It has its roots in 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 electric bass guitar, drums, and one or more singers.
Usually, rock is song-based music with a 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. By the late 1960s "classic rock" period, a few distinct rock music subgenres had emerged, including hybrids like blues rock, folk rock, country rock, southern rock, raga rock, and jazz rock, which contributed to the development of psychedelic rock, influenced by the countercultural psychedelic and hippie scene. New genres that emerged included progressive rock, which extended artistic elements, heavy metal, which emphasized an aggressive thick sound, and glam rock, which highlighted showmanship and visual style. In the second half of the 1970s, punk rock reacted by producing stripped-down, energetic social and political critiques. Punk was an influence in the 1980s on new wave, post-punk and eventually alternative rock.
From the 1990s, alternative rock began to dominate rock music and break into the mainstream in the form of grunge, Britpop, and indie rock. Further subgenres have since emerged, including pop-punk, electronic rock, rap rock, and rap metal. Some movements were conscious attempts to revisit rock's history, including the garage rock and post-punk revival in the 2000s. Since the 2010s, rock has lost its position as the pre-eminent popular music genre in world culture, but remains commercially successful. The increased influence of hip-hop and electronic dance music can be seen in rock music, notably in the techno-pop scene of the early 2010s and the pop-punk-hip-hop revival of the 2020s.
Rock has also embodied and served as the vehicle for cultural and social movements, leading to major subcultures including mods and rockers in the U.K., the hippie movement and the wider western counterculture movement that spread out from San Francisco in the U.S. in the 1960s, the latter of which continues to this day. Similarly, 1970s punk culture spawned the goth, punk, and emo subcultures. Inheriting the folk tradition of the protest song, rock music has been associated with political activism, as well as changes in social attitudes to race, sex, and drug use, and is often seen as an expression of youth revolt against adult conformity. At the same time, it has been commercially highly successful, leading to accusations of selling out.
Characteristics
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. A group of musicians performing rock music is termed as a rock band or a rock group. Furthermore, it typically consists of between three 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.Rock music is traditionally built on a foundation of simple syncopated rhythms in a 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 major and minor modes. 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–chorus structure derived from blues and folk music, but there has been considerable variation from this model. Critics have stressed the eclecticism and stylistic diversity of rock. Because of its complex history and its tendency to borrow from other musical and cultural forms, it has been argued that "it is impossible to bind rock music to a rigidly delineated musical definition." In 1981, music journalist Robert Christgau said, "the best rock jolts folk-art virtues—directness, utility, natural audience—into the present with shots of modern technology".
Unlike many earlier styles of popular music, rock lyrics have dealt with a wide range of themes, including romantic love, sex, rebellion against the establishment, social concerns, and life styles. These themes were inherited from a variety of sources such as the Tin Pan Alley pop tradition, folk music, and rhythm and blues. Christgau characterizes rock lyrics as a "cool medium" with simple diction and repeated refrains, and asserts that rock's primary "function" "pertains to music, or, more generally, noise." The predominance of white, male, and often middle class musicians in rock music has often been noted, and rock has been seen as an appropriation of Black musical forms for a young, white and largely male audience. As a result, it has also been seen to articulate the concerns of this group in both style and lyrics. Christgau, writing in 1972, said in spite of some exceptions, "rock and roll usually implies an identification of male sexuality and aggression".
Since the term "rock" started being used in preference to "rock and roll" from the late 1960s, it has usually been contrasted with pop music, with which it has shared many characteristics; however, rock is often distanced from pop; the former has an emphasis on musicianship, live performance, and a focus on serious and progressive themes as part of an ideology of authenticity that is frequently combined with an awareness of the genre's history and development. According to Simon Frith, rock was "something more than pop, something more than rock and roll" and "rock musicians combined an emphasis on skill and technique with the romantic concept of art as artistic expression, original and sincere".
In the new millennium, the term rock has occasionally been used as a blanket term including forms like pop music, reggae music, soul music, and even hip hop, which it has been influenced with but often contrasted through much of the latter's history. Christgau has used the term broadly to refer to popular and semipopular music that caters to his sensibility as "a rock-and-roller", including a fondness for a good beat, a meaningful lyric with some wit, and the theme of youth, which holds an "eternal attraction" so objective "that all youth music partakes of sociology and the field report."
1940s–1950s: Birth of rock and roll
Rock and roll
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.File:Elvis Presley promoting Jailhouse Rock.jpg|thumb|upright|alt=A black and white photograph of Elvis Presley standing between two sets of bars|Elvis Presley in a promotion shot for Jailhouse Rock in 1957
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 ; "That's All Right" by Arthur Crudup, which was later covered by Elvis Presley in 1954; "The House of Blue Lights" by Ella Mae Morse and Freddie Slack ; Wynonie Harris' "Good Rocking Tonight" ; Goree Carter's "Rock Awhile" ; Jimmy Preston's "Rock the Joint", also covered by Bill Haley & His Comets in 1952; and "Rocket 88" by Jackie Brenston and his Delta Cats, recorded by Sam Phillips for Chess Records in 1951.
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. Four years later, Bill Haley's "Rock Around the Clock" 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. Soon rock and roll was the major force in American record sales and crooners, such as Eddie Fisher, Perry Como, and Patti Page, who had dominated the previous decade of popular music, found their access to the pop charts significantly curtailed.
Rock and roll has led to a number of distinct subgenres, including rockabilly, combining rock and roll with "hillbilly" country music, which was usually played and recorded in the mid-1950s by white singers such as Carl Perkins, Jerry Lee Lewis, Roy Orbison, Buddy Holly and with the greatest commercial success, Elvis Presley. Hispanic and Latino American movements in rock and roll, which would eventually lead to the success of Latin rock and Chicano rock within the US, began to rise in the Southwest; with rock and roll standard musician Ritchie Valens and even those within other heritage genres, such as Al Hurricane along with his brothers Tiny Morrie and Baby Gaby as they began combining rock and roll with country-western within traditional New Mexico music. In addition, 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 Chuck Berry, Link Wray, and Scotty Moore. The use of distortion, pioneered by Western swing guitarists such as Junior Barnard and Eldon Shamblin was popularized by Chuck Berry in the mid-1950s. The use of power chords, pioneered by Francisco Tárrega and Heitor Villa-Lobos in the 19th century and later on by Willie Johnson and Pat Hare in the early 1950s, was popularized by Link Wray in the late 1950s.
Commentators have perceived a decline of rock and roll in the late 1950s and early 1960s. By 1959, the death of Buddy Holly, the Big Bopper and Ritchie Valens in a plane crash, the departure of Elvis for the army, the retirement of Little Richard to become a preacher, prosecutions of Jerry Lee Lewis and Chuck Berry and the breaking of the payola scandal, gave a sense that the rock and roll era established at that point had come to an end.
