Take an oscilloscope. Stick microphone in scope. Hit C on piano, measure frequency. Then hit next note and so on up to octave above. Program Arduino to emit said frequency in accord to button pressed.Right, because it sounds like he probably has an oscilloscope just laying around.....?
Or....google "music note frequency" and find something like this -

Yes but we want this guy to think for himself don't we? If he wants help I think he should present his idea in its entirety so that we can add suggestions. What is this little piano to look like? What are its features to be? How big is it intended to be? Who's it for, us or a specialised niche? All this needs to be revealed so that we can all co-operate. We need to give him a reason to reveal his vision, but if we just hand out easy fixes on tap he will disapeer like all the others and we'll be left with yet another inconclusive thread.
