The changing shape of the hand as one moves up through chord inversions … Interesting how much harder that is on a harp as compared to a piano.
I’m working on it by doing slow, even, and deliberate rolls moving upwards through chord inversions — trying as much as possible to play exactly one string per 8th note, which is harder than it sounds. Then, I work on dotting them. (Again, harder than you think, or than I would have thought, due to the shift in handshape.)
It does make the rolls very even and clean, though — and it makes it easier to shift handshape and move upward. Buzzing is definitely an issue, but I’m oddly finding it to be not as bad as just playing evenly, at least for my left hand, which is better than my right at this sort of thing. I have to admit, that’s a lucky break since one must do more chord work in the left hand, and buzz avoidance is more of an issue down there.
I’m always surprised at how much easier certain things are on the piano versus the harp, probably because I’ve just been playing that one for so much longer (there is no such thing as “hard” or “easy” instruments). But any handshape that goes afield of the typical cluster-of-low-notes-with-an-isolated-high-note on the harp really is a challenge, particularly for that lousy short ring finger of mine. The third inversion is really a pain.
