Hallo @Thatguy v2.0, this prelude is a piece I very loved and I wish I had composed it! 😀 It opens with a subject that – at the first glance – seems to be Baroque-like but introduces strong chromaticism in its second half, so that in mm. 5, when the second voice enters, it reminds me of Bach’s B minor fugue from the WTC I (BWV 869b). But now, in mm. 9, comes the surprise. The mood changes to a more „romantic“ feeling with the arpeggios. And that unexpected change now reminds me at numerous preludes (or fugues) from Shostakovich’s op. 87. I didn’t make an in-depth analysis, but I can see how you have constantly took benefit from using the initial thematic material, which for me emphasizes the effectiveness of counterpuntal technique. Even if I did not recognize more complete entries of the initial subject, I have the feeling that motifs from it recur, even sometimes in augmentation. I enjoyed your effort on articulation, including the pedalling and the rubato, and also the key signature change to Bb minor (or is it Db major?). All in all, a piece very much to my taste. Full of counterpoint, but not in the “Neo-Baroque” style, rather with contemporary harmonies and dissonances and a slight touch of Romanticism! By the way, I’m very curious to know how you’re organizing your preludes (since this is No. 16). Is it a complete cycle based on 16 of the 24 keys? I’m really looking forward to hearing more of them—and have I perhaps already missed one?
