Highwind Theme On Tifa's Piano

By playing:

X, S, T, L1+T, L1+S, X, S, T, L1+X, O, X, S, X

or

Do, Re, Mi, Ti, La, Do, Re, Mi, So, fa, Do, Re, Do

on Tifa's piano in Nibelheim you can play the Highwind (?) theme. Apart from getting the message "Ive heard this melody before. Managed to play well..." and sometimes getting into Tifa's secret stash of 1 Gil does this accomplish anything?

Any other tunes you can play on it?

If you play the tune after getting Cloud back from Mideel, you get a letter from Zangan (Tifa's Martial Arts trainer) and Tifa's final limit break.

yeah and if you get the key back into midgar go back into the shop near don corneos with the gun turret in the top that shoots at you access it again and you get tifas ultimate gloves ^^

True, but her ultimate weapon isnt that great. There is one weapon whose name escapes me, which has a hit ating of 255%. This is better in the long run as Deaathblow will almost always work.

You have to have Tifa in your party when you play the melody on the piano.
