Oftentimes, barbershop singers want to sing something with other men who don't know all know the same arrangement to the same song. Since it can take a while to learn a whole song, we can teach the end of the song, or the tag. The Tag of the song is like a coda; it announces the end of the song. Some tags are written for the joy of a tag, even without the rest of the song. The arranger might place some "meatier" chords in the tag, or a "hanger" or post in one or more voices.
