Rock Research

Rock music is a genre of popular music that developed during and after the 1960s, particularly in the United States and the United Kingdom. It has its roots in 1940s and 1950s rock and roll, itself heavily influenced by rhythm and blues and country music. Rock music also drew strongly on a number of other genres such as blues and folk, and incorporated influences from jazz classical and other musical sources.

The sound of rock is traditionally centered around the electric guitar, which emerged in its modern form in the 1950s with the popularization of rock and roll. The sound of the electric guitar in rock music is typically supported by the electric bass guitar pioneered in jazz music in the same era, and percussion produced from a drum kit that combines drums and cymbals. This trio of instruments has often been complemented by the inclusion of others, particularly keyboards such as the piano.

From the late 1960s the term heavy metal began to be used to describe some hard rock played with even more volume and intensity, first as an adjective and by the early 1970s as a noun. The term was first used in music in SteffenWolf's "Born to be wild" and began to be associated with pioneer bands like Boston's Blue Cheer and Michigan's Grand Funk Railroad. By 1970 three key British bands had developed the characteristic sounds and styles which would help shape the sub-genre.

Christian rock began to develop in the late 1960s, particularly out of the Jesus Movement beginning in Southern California, and emerged as a sub-genre in the 1970s with artists like Larry Norman, usually seen as the first major "star" of Christian rock. The genre has been particularly popular in the United States. Many Christian rock performers have ties to the contemporary christian music scene, while other bands and artists are closely linked to independent music. Since the 1980s Christian rock performers have gained mainstream success, including figures such as the American gospel-to-pop crossover artist Amy Grant and the British singer Cliff Richard.
