Quoted from tvtropes.org
The moment in a song where the refrain comes around for one last time, tempo dramatically slows down, and volume increases to full. Tempo often increases a few bars after for a flashy finish. Common in modern production numbers, where the entire ensemble gets to sing and tap their hearts out. It doesn't have to be the entire chorus, though... or from a musical.
There are some examples listed on the page that describes it, but does anyone know any other things that it forgot to mention, including some that already has a tempo slow down and volume pump up, but then soon after, the tempo slows down even FURTHER and the volume goes up EVEN HIGHER??
