Don’t despair yet… There are several pieces of music which are perfectly playable on the harp. For instance, A window to the Past. Alright, it modulates several times to another key but it isn’t strictly necessary to play those – playing an octave higher or repeating everything a few times also suffices… Double Trouble also sounds rather nice on the harp.
Unfortunately, the sheet music I’ve got is on my other laptop so I can’t look at it right now, but I think I was able to sort of play Hogwarts Hymn as well.
However, I agree with you that you’d probably need a pedal harp for Hedwigs theme… 🙁
@ Anna: Thanks for posting your arrangement, I can’t wait to try it out! I don’t know any violists but it looks as though I could give it a try on the tin whistle…
