How about a book of sheet music for piano that has some of his favorite songs? You could also consider getting him a keyboard or digital piano so he can practice and play at home. Another option could be to purchase tickets to a concert or a performance at a local theatre where he can see professional pianists in action. Finally, you could look into getting him lessons with a local piano teacher who can help him advance his skills and love for the instrument.
Or you can get him a star map with an important date you share.
