Music teachers in all specialties seem to struggle with voice problems. Although little research has been done specifically regarding music teachers, teachers in general are known to be at risk for developing voice disorders that can lead to difficulty teaching or even to leaving the profession.

This article presents a literature-based exploration of the pros and cons of using a microphone in the music classroom, illustrated by a case study of one choir teacher. (Contains 4 notes.)
