Generally, pop music would run for less than five minutes. The instrumentation used to accompany such music could be as large as an orchestra to as small as a lone singer. Generally, a pop band consists of a lead guitarist, a bassist, a drummer, and a keyboardist along with one or more vocalists.

Introduction of such technology made it possible to produce recorded music that was of better quality and much cheaper in price. Because of these reasons, record sales increased quite a lot.
