At the slowest tempo your transcriptions of them for soft piano are exactly the sort of thing that attract me. Some of the passages that are technically easier, but make interestingly mathematical harmonic statements are what I want to try. I will report what I work on.
I find when I listen to music, there are just a few passages or phrases that are most understandable, then as I listen again and again the piece expands around them, and becomes complete, end to end. Starting with those parts that are central to my compression is how I prefer to study, in mathematics, physics, and again now music.
