I’ve been mulling this for a bit — I was able to pull some transcriptions of folk harp tunes from performances on YouTube. Now, these are folk music pieces, so I can make an argument that they are public domain, and that there is nothing whatsoever wrong with making the transcriptions available.
But, they were performed by a particular person (Daniela Ippolito), and while the tunes are public domain, her particular performance of them might not be (and probably isn’t).
I wish I knew what the rules were for this sort of thing. I’ve got about four little pieces (three tarantelle and one waltz) done, and I don’t know the protocol for sharing them.
I should actually just make my own arrangements of them, but Ippolito’s playing is pretty much the ideal for how they would be played to sound their best.
Oy. So I remain sharing only my own personal arrangements of existing pieces in the public domain. *sigh*
