In barbershop music, a tag is a dramatic variation put in the last section of the song. It is roughly analogous to a coda in classical music.

Tags are characterized by heightening the dramatic tension of the song, frequently including a hanger or sustained note against which the other singers carry the rhythm.^[1] In addition, good tags can be sung as short, stand-alone works. Tags may be soft and tender or characterized by loud, "paint-peeling", ringing chords.
