Player1 I will try to be succinct here one more time; the problem is that I'm holding some notes too long in an effort to sustain the dramatic effect of those notes in that particular passage. This is deliberate though subconscious. A secondary issue is that I'm not holding other notes as long as they should be held according to the score.....
Just quoting so you get alerted to a response.
I listened, and then hunted up the original since I don't have the notation. I also read all of what you wrote. I think I understand what you're saying because I had a rough counterpart at one time.
You do keep steady tempo and it doesn't necessarily sound like lack of control. I got the impression sometimes that you were "swinging" the notes to the point that I wanted to ask if you have anything like a jazz background. But I think that was a false impression.
Years back, what I had in music was "feeling" but without understanding of what I was doing. When I started piano with my teacher, having self-taught decades earlier, with a couple of years of violin just before, I had a "cliche" going: dramatically pause at the end of a phrase, die down, then climb up in dramatic pathos .... every. single. phrase. sets. It's effective done once. Otherwise it's "There she goes again!" I had no idea I was doing this - it was "feeling".
Another simple piece, "Williams Song", was repetitive but trying to make it interesting fell flat because in my case the rubato had the correct relative timing of notes, but pulse fell flat. I learned "the power of the One" as in the downbeats- first stage of accelerando & rallentando while preserving underlying pulse. I also learned of "agogic accents" - where you extend a note past its value in order to emphasize it, without losing the value of other notes. (You may be feeling "agogic accent" in the raw here.)
Playing is part feeling, and part dry mathematics. Some are naturally inclined toward the one or the other, and we have to counterbalance. I needed to get the dry stuff. I needed to gain understanding so that I could deliberately apply things in a cerebral way, and then "let go" to the feeling part, "just enough". This is probably what you're at the edge of. 🙂
During part of that journey I'd also find myself doing something that seemed almost effective but I didn't know what I was doing. I'd ask my teacher, "What is it that I did over here?" (recording) and he might pinpoint an actual technical thing - then understanding that, I could play with it and use it.
Does this help or lead anywhere?
