Interesting piece, thank you for sharing. I like the contrapuntal stuff you do with the strings, for example m. 4-9 and m. 32-34.
I wanted to ask what your intention was on some of the metre throughout the piece. There are several places where, as a listener, I feel the time signature to be 6/8, but in the score it's in 4/4. For example, m. 48-52. The feel of 6/8 is so strong here it would make sense to me to write the score in 6/8. Was your intention for the piece to feel this way, or am I missing something?
There are several spots like this where I think the notation would confuse the musicians, m. 62-63 is a notable example. I would try to write this so the rhythmic emphasis occurs on the beat, instead of the second note of a set of sixteenth notes - see below. I might redo the scale at the beginning as a "ten-tuplet" so the E falls on beat 2.
Also there are several spots where respelling the accidentals would make it easier to read. For example the horn solo in m. 82-90 - I would spell all of these accidentals as sharps instead of flats.
Thanks again for sharing, are there any more movements to the symphony?
