Hi Noah, thanks for sharing your piece. I really liked the opening with the tremolo violins above the horn melody, it kind has a "Blue Danube Waltz" feel to it.
One thing I noticed is you have the trumpets entering at Rehearsal B on a high concert Bb. I would think the trumpets would completely dominate the orchestra in this register, I'm not sure if that was the intention after the preceding quiet section. Also in the section you have the Flutes and Oboes on repeated staccato notes, I wonder what it would sound like if instead of repeated notes they were playing a staccato arpeggiated figure. I think this might add a little "flair" to the winds in this section.
I noticed you like to bounce between a 6/8 and 3/4 feel at several points throughout this piece, which is a really neat effect. From a notation standpoint, it would help if you grouped the note stems to make this easier for the performers to realize. For example, at Rehearsal D, group the first two measures as a 6/8 feel, then return to 3/4 for the next few bars that have the "triple" feel. You don't need to actually change the time signature, but group the notes so the rhythmic "feel" is more obvious to the performer.
I wondered if I could also ask you about the form you used. From what I can tell you use AB, repeat AB, development, BA. I was curious how you came up with the structure of the development (starting at Rehearsal G and ending at Rehearsal J). I can find references to the original themes, but some things seem kind of random. For example, the Bb clarinet part 5 measures after Rehearsal H - is this derived from some of the earlier themes, or is it new material? If this is something I'm just missing please feel free to point it out.
Also, was there any reason you chose to recap theme B (starting at Rehearsal J) before you recap theme A (Rehearsal L)? Not that there is anything wrong with doing this, just curious why you decided to flip them in the recap. Btw, I liked your decision to restate theme B in the low strings and bassoons at Rehearsal J, and I liked how the timpani adds to the "bounciness" of the "triple" rhythmic feel here.
Thanks again for sharing!
