Hello Henry,
Great review, as always! I am amazed by your reviewing capacity. How do you find the time to do all this work? It is admirable.
Back to some of your issues:
About the sonata form, I agree with you (see my reply to Carl).
Funny that you mentioned b. 71. I had exactly the same feeling as you described. Is this repetition going to be boring? But then ….. I left it, since the surprise comes a few seconds later.
The theme in b.101 is indeed reminiscent to the theme in Schubert´s D 960 sonata, as you mentioned but there are some distinct differences in construction and functionality. Schubert used this theme as a vehicle for a series of modulations (incredibly beautiful). In my case, the left hand melody notes starting in b. 101-104 followed by the right hand melody notes of b. 105 -118 constitutes an essential melodic frame of the piece, which is recurring many times (in different forms). There is also a difference in the arpeggio and bass notation structure, in line with the functionality.
Although these progressions are probably not in accordance with standard rules, I do not perceive them as unpleasant or jarring. I often use unusual transitions/modulations and of course, not everybody will like these constructions. But that is the freedom we have as composers- to jump a bit away from the conventions.
I agree that I should review more music of the other members. The problem is that I am a very slow reviewer and I do not have the available time for it . It can take me more than a day to provide a constructive feedback. But I will start to review some selected pieces.
Thank you very much again for your comprehensive and constructive inputs!
Johan
