thanks Pianowolfi for your comments. Yes, I actually suspected you'd like that part between 2:30 and 3:30. I like that sort of atmosphere a lot, too. At the end of that passage where I play some very simple textures---that's something I'm working on. What amazes me about music is that no matter what the style, no matter how many notes, the number of possibilities for atmosphere and expression are quite literally limitless!
You said:
"And, you know, the most interesting sort of picture or imagination that can appear is one that can't be compared to anything in the environment. Something that "looks" somehow as if it would be a landscape or a forest but in fact it isn't. It is something undescribable. I try to combine the "inner senses" when it comes to art, especially to music. Because after all the "whole thing" is so huge, so big that it is beyond our "normal" five senses. Isn't that wonderful? And I am searching and starving for these moments in music. You are coming very close sometimes!"
This is very much how I feel, also. I like those abstract responses I get from music which could ALMOST be describable images but are more something that one would experience in a dream.
