A vocal coach, also known as a voice coach, is a music teacher, usually a piano accompanist, who helps singers prepare for a performance, often also helping them to improve their singing technique and take care of and develop their voice, but is not the same as a singing teacher. Vocal coaches may give private music lessons or group workshops or masterclasses to singers. They may also 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. While some vocal coaches provide a range of instruction on singing techniques, others specialize in areas such as breathing techniques or diction and pronunciation.

Vocal pedagogy is the study of the art and science of voice instruction. It is used in the teaching of singing and assists in defining what singing is, how singing works, and how proper singing technique is accomplished.
