I agree! I really like the flute adaptation – http://www.youtube.com/watch?v=8SIF1CuNOVE (I never knew that the transverse flute could sound so beautiful… Prior to watching this video, I’d only seen little children play the flute. Somehow, I never thought that it was possible to get such a clean sound out of it!).
Anneleen Lenaerts apparently won a prize for the best rendition of the Bach Chaconne on the harp in a major competition, but I haven’t been able to locate her CD yet. (Her Chopin CD is on spotify – It’s great! I like Chopin music better on the harp than on the piano…)
I’m very curious, because the versions I’ve seen on Youtube don’t seem to convey what’s in the original. Perhaps it’s also because we can’t really modify the sound after we’ve plucked the string? A flute player can modify it with their breath, and violin players can do a lot by bowing etc, but as soon as we leave the string, the sound is just there.
