Okay, here is a tremolo attempt based on what was recently discussed. I did a tremolo, attempting to maintain the level of supination in the previous attempt (although this may have "slipped back" a bit) and anchored on the bridge. This time I'm trying to do a rest stroke in both directions or trapped motion maybe, as discussed earlier. I did a few takes of this and I thought this was the best one overall and actually just my second take. I got a bit "noisier" after this and then I did a fifth and final take which was possibly cleaner; but strayed to a more pronated form, I think.
