Wow, @Rich. This is an immense work. It is difficult to provide constructive feedback on something with such depth. I would, though, like to hear more about your influences for this work. Who are your role models and the style you are emulating?
Markus---
Thank you for your comments. I don't know how much depth it has!---but I did shoot for coherence and a logical form. I must admit I am proud of it as far as thematic unity--melodic and rhythmic motivic fragments help to unify it--the opening, the three sections of the developments, and even in the coda. I really just had to trust our great teachers from the past and put as much craft into it as I could. And, I know, my mom's passing fueled what feeling made it into the later portions..
I started the 1st mvmt looking to Mendelssohn and Ferdinand Ries(Beethoven's pupil and friend, and a fine composer himself)--definitely "early" romantic composers, but looked and listened to a lot of Schumann and even took to Brahms' own PQs as time passed.
I think the basic musical language is early romantic--thematic vs. motivic development, clear diatonic harmony. The "quiet" interior of the piece--the chorale--is my take on Mendelssohn invention he used in developments and caught on. It worked back in the 1830/40s because it was new--- instead of amplifying as in classical development, you take a step down before a more energetic close to the development (here the fugato).
More generally, I love late Schubert- the piano trios and quartets. Spiritually, he has to be an influence. The rest, I guess, is me.
My own criticism of the piece is an overly formal statement of themes. The hardest portion to write was the "A" section of the development, as chopping up and playing with fragments requires the most work, musical sensitivity,and skill---rapid modulations, changes of rhythmic patterns/motifs, etc... I defintely want to focus on this more on my next piece--a violin sonata (to be written on Dorico for the first time!).

The neat score is due to my pianist holding my feet to the fire--as I asked her-- to produce a clean, usuable score/parts for performers--a new consideration! She has been great. And thanks, it took a lot of work and time!---and I'm not done!
Anyhow, I just signed on my string trio, and am mentally juggling a rondo theme around in my head, almost ready for pen and paper. I would like to have it done by early may and in my pianists hands --she needs 4 or 5 weeks to work on it-- for a June workshop. I've never worked like this--with a deadline of sorts--and it is a bit unpleasant! If I blow by this deadline, my group has to bring on a new violist---a little hickup. I told them I'm not going to botch it up just to have it done, however...
I want it to be fitting for the piece as a whole and tie it together style-wise. I'm thinking of a call back of the chorale from the 1st movement in the coda, and a major key ending, honoring my mother, and wishing her peace.... Mainly, I need about 50 hours uninterrupted work time!! Fat chance of that....
Thanks again for your kind words and interest! You are a fine composer, and your thoughts have weight! My life is a bit like an American country music song right now, and this gives me a real lift!
