I've been doing some basic research on i-m alternation with a cool camera that captures 1,000 frames per second. Not very expensive, either, for such a video camera. Got it new from Japan through eBay.
What I'm watching in particular are the differences between i and m. My m is fantastic. I'm trying to get it to teach my i. But they are very different fingers. In particular, i at rest is much more extended than m at rest. In Arpeggios, I think my i would be happier playing one string higher than m, rather than lower, frankly.
The problem at the moment is that, compared with m, i has to flex several degrees tighter (away from midrange) in order to play the next-lower string in an arpeggio. In a fast, continuous arpeggio, this encourages i to accumulate tension. It has to do more flexing than m to hit the string, and it tends to want to *stay* flexed. Mine does, anyway. m is much more relaxed, doing all of its work cloer to midrange.
The same goes for i-m alternation on a single string. i hardly has time to return to midrange before it has to turn around and flex again. The only way to get it to relax all the way out to midrange is to greatly overshoot the string on return.
I'm guessing that when I was decades younger and a hot player, my i was conditioned to be more relaxed in a more flexed position. (Shearer's "prepared" position.) Nowadays, when my i returns to the prepared position, it's not relaxed at all. I have to extend it quite a bit farther to get to its relaxed midrange. So it's way out of position, or so it feels.
I was looking at some slo-mo video of an older Yamashita the other day. He was playing blazing fast i-m alternation, and I noticed he was really overshooting the return with i. Taking a BIG swing with i, compared with m. "Swinging from the heels," as they say in baseball. I wonder if that's something he developed as he got older.
Anyway, it's interesting fooling around with this slo-mo video cam. Basic research.
