Thanks again Frank for the clarifications.
I must say, also in relation to Piccinesco's discussion, that in reality there aren't many aspects of my pieces that I intend to leave to the free interpretation of those who will perform them. The reason, as you know, is very simple: I don't expect anyone will ever perform one of my pieces. I believe this assumption has conditioned all my music so far, for better or for worse. For the worse because, obviously, my writings are almost never carefully prepared. I have a bunch of music that is almost indecipherable even to me, and unfortunately the only one who understands anything is... the blessed sequencer. For the better because, as I was saying, I actually try to imagine the result in every minute detail, and this is because, usually, I always have the piece performed by a virtual instrument. It's just that the markings are not those that interest a human eye, but those that interest the specific virtual instrument being used. For example, I don't know if you remember, but some time ago I published a score on which some strange little symbols had slipped through; someone asked me what they indicated and I replied that it was the sequencer's agogics. Or again, yesterday I went back to some wind scores and found them full of indications that, after a year, even I no longer know how to interpret, simply because when I indicated them, I had to make them up on the fly, not knowing the common practice (for instance, if I wanted an up-bend on a trumpet, I would associate the relative articulation with a certain note outside the trumpet's range; then, since there are dozens of articulations over time, it's easy to get lost...). Luckily for me, there are (though not always, unfortunately) playbacks that remind me what I intended to do at a certain point. Unfortunately, obviously, a virtual instrument never quite manages to achieve what I imagine, but it at least gets close (for a while now I've been using the finale function which is supposed to interpret the dynamics I write, but most of the time it's a torture and never does what I expect, I don't know if due to my lack or its own).
Coming to the fugue in question, what you pointed out is all correct. For example, the bizarre accidentals—I hadn't even noticed them, and if I told you the reason why they are there, you would start laughing. However, in the meantime, I discovered something new: that in finale I can and must set the note spelling criteria. As for the rest, I must say it was the first time I was writing for organ, so—what did I do?—I went to look at some scores and, with little time available, I formed a certain idea, probably an inadequate one. I had also chosen the timbres and they are even indicated in the score, but on an additional staff in the form of notes (keyswitches) which I then deleted during the printing phase. The chosen timbres are, obviously, those I deduced from the instrument I had available at that moment. However, unfortunately, I couldn't get it to play without a strange swing that it introduces on its own, so in the end, I diverted everything to what was proposed by Croma. Out of curiosity, if you're interested, I put both versions on YouTube where the video shows the changes in registers.
By the way, the desired registers would be:
principale,
+flauto from measure 6 on high manual
+viola gamba from measure 8 on low manual
+ottavino from measure 14 on high manual
+bombarda from measure 14 on low manual
principale from measure 15
+flauto from measure 20 on high manual
plenum from measure 31
+ottavino from measure 14 on low manual
From a structural point of view, it is a work that invents nothing new, and it was precisely in the ironic and somewhat lighthearted gesture that I intended to center the entire message, all the more so knowing the original theme. My intention was to show how even in a formally standard fugue, one could find with little effort a character that pieces of this kind usually do not show. Hence the title, which in itself provides all the context. Measure 14 should be seen as a sort of alarm bell, but it must, in my design, stay only there, because that is its function. If it had achieved its purpose, it would have been a work that could have said something about music, but unfortunately it failed, and this makes me understand the importance of what you are saying.
I am saying all this not to justify myself, but only to make it understood that I don't write like this just to spite someone, or perhaps out of a sort of snobbery (this was actually what I thought when you said that it is starting to become tiresome), but simply because of the situation I am in and due to my own shortcomings.
And all the more so, having said that, I wouldn't want anyone to stop pointing out where I fall short: on the contrary, it will please me even more, because for me you are a very important help in this as well.
