I Introduction
Rock Music, group of related music styles that have dominated popular music in the West since about 1955. Rock music began in the United States, but it has influenced and in turn been shaped by a broad field of cultures and musical traditions, including gospel music, the blues, country-and-western music, classical music (see Music, Western), folk music, electronic music, and the popular music of Asia, Africa, and Latin America (see Worldbeat). In addition to its use as a broad designation, the term rock music commonly refers to music styles after 1959 predominantly influenced by white musicians. Other major rock-music styles include rock and roll (also known as rock 'n' roll), the first genre of the music; and rhythm-and-blues music (R&B), influenced mainly by black American musicians (see African American Music). Each of these major genres encompasses a variety of substyles, such as heavy metal, punk, alternative, and grunge. While innovations in rock music have often occurred in regional centers—such as New York City; Kingston, Jamaica; and Liverpool, England—the influence of rock music is now felt worldwide.
II Musical Elements
The central musical instrument in most kinds of rock music is the electric guitar. Important figures in the history of this instrument include jazz musician Charlie Christian, who in the late 1930s was one of the first to play the amplified guitar as a solo instrument; Aaron Thibeaux “T-Bone” Walker, the first blues musician to record with an amplified guitar (1942); Leo Fender, who in 1948 introduced the first mass-produced solid-body electric guitar; and Les Paul, who popularized the instrument in the early 1950s with a series of technologically innovative recordings. Rock-and-roll guitarist Chuck Berry established a style of playing in the late 1950s that remains a great influence on rock music. Beginning in the late 1960s a new generation of rock guitarists, including Jimi Hendrix, Eric Clapton, and Carlos Santana, experimented with amplification, feedback (a type of electronic sound distortion), and various electronic devices, extending the musical potential of the instrument.
Other instruments commonly used in rock music include the electric bass guitar (introduced by Fender in 1951); keyboard instruments such as the electric piano, organ, and synthesizer; and the drum set, an African American innovation that came into rock music from jazz and R&B music. Instruments that play important roles in certain rock-music genres include the saxophone—prominent in jazz-rock and soul music—and a wide assortment of traditional instruments used in worldbeat music. The microphone also functions as a musical instrument for many rock singers, who rely upon the amplification and various effects (such as echo) obtainable through electronic means.
Rock music also shares more complex technical aspects. Most rock music is based on the same harmonies as Western music, especially the chords known as tonic, subdominant, and dominant (see Harmony: Functional Chord Names). The chord progression (series of chords) known as the 12-bar blues is based on these chords and has figured prominently in certain styles, especially rock and roll, soul music, and southern rock. Other common harmonic devices include the use of a drone, or pedal point (a single pitch sustained through a progression of chords), and the parallel movement of chords, derived from a technique on the electric guitar known as bar-chording. Many elements of African American music have been a continuing source of influence on rock music. These characteristics include riffs (repeated patterns), backbeats (emphasizing the second and fourth beats of each measure; see Musical Rhythm: Pulse and Meter), call-and-response patterns, blue notes (the use of certain bent-sounding pitches, especially those related to the third and fifth degrees of a musical scale), and dense buzzy-sounding timbres, or tone colors.
The musical form of rock music varies. Rock and roll of the late 1950s relied heavily upon 12-bar blues and 32-bar song forms. Some rock bands of the late 1960s experimented with more flexible, open-ended forms, and some rock bands of the 1970s developed suite forms derived from classical music. Another important formal development in rock music has been the so-called concept album, a succession of musical pieces tied together by a loose narrative theme.
Much rock music is performed at high volume levels, so the music has been closely tied to developments in electronic technology. Rock musicians have pioneered new studio recording techniques, such as multi-tracking—a process of recording different song segments at different times and layering them on top of one another—and digital sampling, the reproduction by a computer of the patterns of a particular sound. Rock concerts, typically huge events involving thousands of audience members, often feature high-tech theatrical stage effects, including synchronized lighting.
Rock music is a genre of popular music with a prominent vocal melody, accompanied by electric guitar, bass guitar, and drums. Many styles of rock music also use keyboard instruments such as organ, piano, mellotron, and synthesizers. Other instruments sometimes utilized in rock include saxophone, harmonica, violin, flute, French horn, banjo, melodica, and timpani. Also, less common stringed instruments such as mandolin and sitar are used. Rock music usually has a strong back beat, and often revolves around the guitar, either solid electric, hollow electric, or acoustic.
Rock music has its roots in 1940s and 1950s rock and roll and rockabilly, which evolved from blues, country music and other influences. According to Allmusic, "In its purest form, Rock & Roll has three chords, a strong, insistent back beat, and a catchy melody. Early rock & roll drew from a variety of sources, primarily blues, R&B, and country, but also gospel, traditional pop, jazz, and folk. All of these influences combined in a simple, blues-based song structure that was fast, danceable, and catchy."[1]
In the late 1960s, rock music was blended with folk music to create folk rock, blues to create blues-rock and with jazz, to create jazz-rock fusion, and without a time signature to create psychedelic rock. 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, 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 a 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, and/or horns like saxophones, trumpets or trombones. |
