@Marc O'Callaghan Thanks for pointing out the large gap between the basses and sopranos, I myself am a pretty low bass, and I love the way open voiced chords (as in a lot of Eriks Esenvalds' pieces) sound, although I forget to think about how hard they can be to sing/ tune for amateur voices! Now that you pointed it out, it makes a lot of sense about the octaves/ fifths, as there may even be room for a countermelody or something else!
@Adrian Quince Thanks for the feedback! As I've listened back to the recording, I agree that the quick dissonances in the soprano, especially in the climax, are really difficult to tune, and almost sound like errors sometimes! As far as the difficulty level, my professor sent it into his publishing house, and they told him that it is a little too easy for college and too difficult for all except the best high school choirs. They said it would be really difficult to sell and publish because of this!
