One idea could be to get him a unique or rare musical instrument to add to his collection. You might try looking for vintage or one-of-a-kind instruments online or at specialty stores. Alternatively, you could look for a music-themed experience, like a concert or a workshop where he'll have the opportunity to learn more about different instruments and even try them out himself. Another fun option could be to create a "musical care package" with a mix of smaller items - like sheet music, new picks or strings for his existing instruments, or even novelty music-themed socks or t-shirts. Hope these suggestions help!
Or you can get him a star map with the date when he was born.
