Thank you so much for the feedback!
This one has a splendid opening, better than my openings anyway, which are reliably weak.
Just wanted to clarify that this is an excerpt from a long recording (around 25 minutes). This is about 17 minutes in, I think (if you would like to hear it, please let me know; I could upload it here). I tend to only post the parts I consider interesting.
Double notes can sound nice with that sort of texture too. With a few weeks practice you can get just as fast with them as with single notes, and they offer a wealth of harmonic combinations.
By double notes, do you mean thirds with one hand, or both hands playing scales a third (or some other interval) apart (such as 0:57 in the video)?
I really appreciate your help, Ted! You're one of the few people I have seen who strongly believe in free improvisation, and I feel that my personal idea about improvisation resonates with yours in that it, in a sense, involves a continuous spectrum from predictability to chaos. I don't know how to express it adequately, but it is very similar in principle, I think, to the post you made a few weeks ago when you drew an analogy to algorithmic pattern generators.
