Great playing and welcome to PWF! It's really interesting how you've thought about this piece and interpreted by ear. Best wishes for your journey of music.

Nice, and interesting!

By the way I think it would help if we say more about exactly what this is:

Opening movement of Orff's Carmina Burana.

I wouldn't have known if not that I've played it -- I was lucky to be the accompanist of my college's chorus when they did the piece.

Just a couple of thoughts:

I said it's "nice," and actually it's sort of 'too nice' to my taste.
I've always seen it as building to a much bigger crescendo and climax, and I think it's how I've always heard it. Of course that doesn't mean you can't do it this way, but....I think you're conceiving of it differently than usual in this respect and I wonder if you realize that you are.

Also, a detail: I think you wait much too long after the introduction before starting the main part, even with your different kind of conception. In fact, I think if anything, it's even more so with your kind of conception because if you're going to be staying so 'small-ish' in the main section, I would think it would be best to launch into it sooner rather than later.

Do you mean I should play the intro faster???

My main suggestion would be that the main theme has to played with greater rhythmic steadiness because it's the endless repetitive rhythm that gives a lot of the drama to this piece. I would also play it slightly more slowly.

Chumachenko transcribed all of Carmina Burana for piano solo. The opening line of O Fortuna has several six note chords for left hand alone.

I wonder how could my 5 fingers by my left hand press on the six notes chord alone ^^
