A vocal coach (also known as voice coach) is a music teacher who instructs singers on how to improve their singing technique, take care of and develop their voice, and prepare for the performance of a song or other work. Vocal coaches may give private music lessons to singers, or they may coach singers who are rehearsing on stage, or who are singing during a recording session. Vocal coaches are used in both Classical music and in popular music styles such as rock and gospel.
