Wow, Bach?! I appreciate the praise, but this work is far too distant from Bach's magnitude,

. Anyway, this prelude may soud a bit Bachian maybe because it's been conceived to precede a fugue (which already existed), at first. However, after a certain time, it has gone into another mood and I decided it to be an independent piece.
Yes, I've heard Beethoven's tempest. I LOVE it! The third movement is my favorite! In fact, I love (almost) all Beethoven sonatas, they're delightful (as opposed to Mozart ones, which I think are rather childish and artificial... it's not my preference, but I respect and understand his brilliant contribution). This 3rd movement has an hypnotic something too, but I didn't think about this hypnotic effect. It just appeard. In fact, I was thinking in mystery.
Thanks for comments!
