Thank you, of course I appreciate it.
Regarding the end of the response in the exposition, I should try to accept your suggestion; however, it seems to me that it would not lead back to the key of A minor for the tenor subject, which is instead what I achieve with a plagal cadence.
A premise on this blessed fourth bar of the subject: the essential reason why I don't like it is that that phrase should naturally be distributed over two voices: two quarter notes on the first and third accents (the E and the G#) and the eighth notes in the upper voice making that type of movement; this is what that melodic flow suggests to the ear. As it is, it seems to me a bit of a "muddled" synthesis, as they say in Rome. But I myself, shortly after, as I wrote in response to Dilettante, did something similar (which, in my opinion, is an error).
That being said, the fragment of descending scale prolongs the closing of the subject, in my intentions weakening its effect from a rhythmic point of view (since I didn't like it...). In any case, to make the melodic discourse more fluid, in my exercises on the genre I have always tried to do the same thing, namely to link the end of the subject with the beginning of the response so as not to compete with the entry of the countersubject. But it is a pure matter of taste.
More specifically, bar 5, this was my reasoning: assuming that the response requires a note on the strong beat for a natural conclusion of the subject, this can be (for melodic linearity and without a tail) either the C that I wrote, or the E; and I chose C instead of the octave, for harmonic completeness; you add the low A (which I connected via B with the eighth notes), and you have the 4/6 inversion of A minor, to which F# is immediately added, leading straight to the V of V in the following bar. And so that inversion of A minor becomes an appoggiatura on the V. From a rhythmic point of view (which by instinct I look at before anything else), I chose the stop with the quarter note on the second accent to leave the effect of the syncopation of the countersubject's entry free, which makes it immediately recognizable (otherwise, for example, the response on the strong accent could have been the series of four eighth notes C B C D, closing on the E that I wrote in the middle of the bar). In short, I had reasoned it my way... I imagine that, as in chess, there is no best move; but I liked this one, so much so that I later picked it up again playing with it here and there.
I would be very interested to better understand the relationship you highlighted between the conclusion of the subject and the harmonic connections (but perhaps I would be asking you to go too deep into the details compared to the attention you have already kindly dedicated to me).
Regarding the stretto, you are certainly right, it's just that I didn't quite succeed; I felt very constrained by that leap between the first and second bars of the subject, which in fact I like almost as much as the fourth bar (Mozart will come to pull my leg), more or less for the same reasons: I feel like keeping the F above the G#, which become two voices...
Regarding the sustain of the sound, I don't remember Schumann's rules; however, I tried to take into account the fact that the organ is generally played more staccato than the piano (due to environmental reverb) and, in the playback realization I made, you will easily notice that especially the long notes last less than their written value. Only in the slurs did I use the full duration of the notes included therein (but not in those at the end of a slur, moreover). I must also say, however, that when listening to the harmonic layout, I used the organ (precisely because I know that harmonic messes are heard more clearly) before reducing the actual duration of the notes and at an extremely slow tempo; therefore, if there are questionable passages in this respect, I cannot say I didn't hear them.
Naturally, if you or anyone here wanted to point out some harmonic ugliness in detail, I would consider it a courtesy.
I prefer the piano not only because the dynamics make the movements of the lower voices more perceptible, but also because one can emphasize this or that passage, the entry of even an intermediate voice, or better perceive the "polyrhythmic" aspect determined by the overlapping of the voices.
As for the pauses, as I explained to Bianca, since I started with the idea of the organ, I used the pauses as a function of changes in registers or manuals. In practice, it was about alternating different timbres (or "atmospheres") between the different sections, but it is certainly true that I could have made more strategic use of them; it's just that I wouldn't know how to identify any key episodes of the composition, because within the
divertimento there isn't a real recovery and there isn't a nice final section for the stretto, or a nice tonic pedal.
