A singer is an artist or performer who crafts a vocal song using various techniques and training. Singers often practice daily and will hire professional voice coaches to help them hone their craft. Singers may write their own music or sing music written by others. In addition to singing, singers may work as music teachers or voice coaches. Professional singers are highly talented and have an excellent ear for identifying tone and pitch. Singers often freelance and are contracted on a per job basis, either as a singer or as a consultant or judge in singing competitions.

Professional singers may be employed by a record label that finances the development and recording of their music. Other singers may be employed by companies including radio advertising firms and variety show theatres.
