Of all the things that have occurred to Adagio and her sisters since their arrival in the human world, nothing has cut quite as deep for them as the loss of their once-beautiful singing voices. However, since becoming friends with their one-time enemies, the Rainbooms, they've gradually started to regain those notes.

Their true test, however, comes when the school hosts a talent show, and the three, at long last, decide to finally go out and see what they can do.
