In music a singer or vocalist is a type of musician who sings, i.e. uses the voice as an instrument to make music. A lead singer is one who sings the primary vocals of a song, as opposed to a backup singer who sings backup vocals to a song or harmonies to the lead singer.

In classical music and in opera, voices are treated just like musical instruments, thus special careers were developed out of each principal pitch.
