Tag (barbershop 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. In addition, good tags can be sung as short, stand-alone works. Tags may be soft and tender but are typically characterized by loud, "paint-peeling", ringing chords. According to the competition rules of the Barbershop Harmony Society, every song entered for a competition must have a tag.
