I would be very keen to get constructive criticism and feedback on a couple of pieces I've written for solo french horn recently.
They share the same thematic material (a 6 note chord spanning a major 7th, presented as a series of pitches) and try and explore what happens if you make the "octave" have 13 semitones rather than 12 semitones, but treat the thematic material in very different ways.
I have got a (good) horn player to play them through to me, so I know that they are playable, if not easy!
I'm not after hagiography. I don't mind criticism or statements like "I don't think this is very good", so long as people suggest ways to improve the pieces, or explain what it is that they don't like.
Thanks for taking the time to read
