Vocal performers are distinctive due to the self-discipline that necessarily accompanies having one's voice be one's instrument, as all life choices directly affect a vocalist's ability to sing. Vocalists are also united by a strong feeling of self-confidence that is essential in a field that is highly competitive, subjective, and personal. Furthermore, while a love of music is a common theme for many musicians, vocal performers are distinguished by both the emotional and physical connection that they must forge with their music.
