How about purchasing tickets to see a performance by her favorite piano player or composer? You can also consider gifting her a book on the history of piano music, a piano sheet music book of her favorite songs, or a personalized piano key necklace. If she doesn't own one already, you can even gift her a digital or a keyboard piano that she can practice and play at home.
Or you can get her a star map with the date of your first kiss.
