Rock music (or rock) is a loosely defined genre of popular music that developed during and after the 1960s. It has its roots in 1940s and 1950s rock and roll and rockabilly, which evolved from blues, country music and other influences. In turn, rock music drew on many other musical influences, including folk music, jazz, and classical music.
The sound of rock often revolves around the electric guitar or acoustic 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, digital 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, or horn sections of saxophones, trumpets or trombones.
Pop music as a genre features a noticeable rhythmic element, melodies and hooks, a mainstream style and conventional structure. The term is also sometimes used to refer to any piece of music that appears in popular record charts due to a high number of sales and/or airplay - a subject treated in the article Popular music.
In opposition to music that requires education to appreciate, a defining characteristic of pop music is that anyone is able to enjoy it. Artistic concepts such as musical form and aesthetics are not always a concern in the writing of pop songs, the primary objectives being audience enjoyment and commercial success. This of course does not imply that those goals are achieved by every song in this genre.
The term "pop music" was first used in 1926 in the sense of "having popular appeal", but since the 1950s, it has been used to designate a musical genre, originally characterized as a lighter alternative to rock & roll.
The standard format of pop music is the song, customarily less than five minutes in duration, and with an instrumentation that can range from an orchestra to a lone singer. Despite this wide scope, a typical lineup in a pop band includes a lead guitarist, a bassist, a drummer (or an electronic drum machine), a keyboardist and one or more singers, who may or may not themselves be instrumentalists.
Pop songs are generally marked by a consistent and noticeable rhythmic element, a mainstream style and traditional structure. The most common variant is strophic in form and focuses on melodies, catchy hooks and the appeal of the verse-chorus-verse arrangement, with the chorus sharply contrasting the verse melodically, rhythmically and harmonically.
Some of the most common themes in pop music are romantic love and feelings, although lyrics about life experiences are also common. Pop music often uses the technique of taking themes from other records producing a satirical or self-referential mixture of past styles. It also employs techniques of sampling and sequencing to introduce individuality and creativity.
