Why hello there, Henry... the infamous Henry that I hear so much about. You're the talk of the town, the word on the street, the....
sorry, I'm dumb
I like this piece of yours. You mentioned it's your least favorite (I won't tell you not to do this anymore since you seem insistent to do so). Just because it doesn't have heavy emotional depth doesn't make it bad. I think it's what your sonata needed. A chorale 1st mvmt, a vigorous torrent of notes for the 2nd, and a jovial 3rd mvmt seems fitting. I know the character of the 4th, so I think with what I've heard so far it's what the music needed, not necessarily what you wanted to write.
That said, this was really cool. It's like Bach meets the Eroica symphony. I don't have much to gripe about, but with the previous 2 movements, you could have maybe made the overall texture a bit lighter. I like what you did, but was hoping for more spots with a single line and accented with light staccato chords or something. As is, it seemed more dense than it needed to be.
I agree about the comment of the chord at b.142. I don't think it was out of place necessarily, but a deceptive cadence or something along those lines might be advantageous to the music.
All in all though, wonderful piece Henry. As much as I enjoy your compositions, I get just as much excitement out of your performance and ability to bring this to life. Fantastic music, can't wait to hear all 5 movements together!
