In the latter half of the game, when Cloud rejoins your party, go to Tifa's House in Nibelheim with her in your party. You can play a sequence of notes on the piano in order to obtain the Final Heaven, the item needed for Tifa's Limit Break. After playing all the notes, press Start. The button sequence corresponding to the notes you need to play is below: hyphens separate individual buttons, and buttons grouped in parentheses with a plus sign mean to press them together. For example, "(A+B)" means to press A and B simultaneously, where "A - B" means to press A, then press B.
