CALLANDRESPONSE
Call and response
In music, a call and response is a succession of two distinct phrases usually played by different musicians, where the second phrase is heard as a direct commentary on or response to the first. It corresponds to the call-and-response pattern in human communication and is found as a basic element of musical form, such as verse-chorus form, in many traditions.The above text is a snippet from Wikipedia: Call and response (music)
