If i want to use piezoelectric, it is possible or there is another better idea to do this. My idea is to make it self-powered so that it could recharge the battery.

Miniature coils and the keys hold small magnets... just an idea
Edited:
One may get a patent for it :-D
Or
By pressing any key the whole board of the keys also moves and generates the pulse in one wide coil.
That's is a good IC for this project. it can operate in low power as my project is using piezo for low power appliances. Now my only problem is to get the suitable piezoelectric as it is the main item for the whole project.
I think a musician should be quite sensitive to keyboard keys. Generating a usable power through the keyboard is not a good idea. But you can use the pedal which is usually pushed by a foot with a good force. This is where I would try to start. Find a strong magnet (neodymium) and a flat coil, and give it a try.... Maybe you can mechanically drive a flywheel first, then connect it to a small DC motor as a generator, to get a smooth output.
