Playing the piano

...Does the piano in the Shinra Mansion actually does anything besides giving out notes?

It has the secret to reviving Aeris.

Good. And then? :P

Well, first you have to level up the revive materia until you get resurrection, then you have to attack Tifa with morph until she turns into Mozart, then you'll play the piano and Aeris *magically* appears. :eek:

and on that day satan will be driving to work in a golf GT.
