rock band

A rock band or pop band is a small musical ensemble that performs rock music, pop music, or a related genre. A four-piece band is the most common configuration in rock and pop music. In the early years, the configuration was typically two guitarists, a bassist, and a drummer. Another common formation is a vocalist who does not play an instrument, electric guitarist, bass guitarist, and a drummer. Sometimes, in addition to electric guitars, electric bass, and drums, also a keyboardist plays.
