A bandleader is the leader of a music group such as a dance band, rock or pop band or jazz quartet. The term is most commonly used with a group that plays popular music as a small combo or a big band, such as one which plays jazz, blues, rhythm and blues or rock and roll music.[1] Most bandleaders are also performers with their own band, either as singers or as instrumentalists, playing an instrument such as electric guitar, piano, or other instruments.
