frontman

A singer is a musician who uses their voice to produce music. Often the singer is accompanied by musicians and instruments. While many people sing for pleasure, vocal skill is usually a combination of innate talent and professional training. A lead singer performs the primary vocals of a song, as opposed to a backing singer who sings backup vocals or harmonies. An exception is five-part gospel a cappella music, where the lead is the highest of the five voices and sings a descant, and not the melody. Professional singers usually undergo voice training, provided by a voice teacher or coach.
