For musicians on this budget, there aren’t many truly practical things at least nothing they don’t already have Perhaps a good notebook with music paper Or something similar, like a mug with a photo of their favorite composer or something similar
If you roughly know the recipient’s skill level and musical style, why not a sheet music collection Anything under 15 is a bit steep Does the recipient have other hobbies they enjoy Honestly, I generally advise against giving anyone a serious hobby unless they’ve specifically asked for it or you share the same hobby and know what to look for You won’t find much useful, especially for 15, and on the rare occasion you do find something suitable, the recipient probably already has it I know it’s awkward to give generic gifts, but I’d rather give a nice box of chocolates or some tea blends than any hobby gift they’ve received over the years except the ones I asked for If you want a more personalized gift, you can always go for a themed gift, like a mug with the sheet music for one of the recipient’s favorite pieces However, I don’t recommend looking for something practical
