I did not like this very much in it's first incarnation, as a song. It became an accompanied violin duet, which was an improvement. This is the final re-incarnation, for flute and piano. The violin version will be posted soon.
I'm always in for a good flute part and this is quite a piece! However, I'm missing a bit the direction of the music. There are a lot of good ideas and unexpected turns in harmony, but the meaning of it remains unclear to me. The flute sounds well, but the indicated dynamics are not followed by the performance. (Did you use the modwheel instead?)
