Rock N’ Roll History

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.
The influence of rock and roll is far-reaching, and has had significant impact worldwide on fashion and film styles. Its impact has been positive as well, with the trend of many rock stars facilitating charity events such as Live Aid. Saving the World is becoming a more and more common phrase associated with rock music today. There are also spiritual aspects tied to rock music. Songwriters like Pete Townshend have explored these in their work. The common usage of the term rock god acknowledges the religious quality of the adulation some rock stars receive.
