Since I don’t want to spam (any more ) in the Downpicking thread I will post my videos in this dedicated one. You can see my previous posts and videos there.
So, as I promised I will keep you updated on my quest for fast downpicking and tremolo! After a about a week of experimenting with the wrist extension/deviation approach I decided to give it up in favour of the forearm rotation. It’s just not working for me - it feels inconvenient and I’m much slower with it. The only difference is that now I do forearm rotation without the extreme wrist bend. I find that it’s working this way too and it’s more ergonomic.
I made a video comparing both approaches. First is wrist downpicking/tremolo at slow speed and at faster (close to my limit) speed. Then I do the same with the forearm approach:
And here is the same video at slow speed:
Note: I know that the forearm is also moving in the wrist approach but it’s a “parasitic” motion. The main drive comes from the wrist. In the forearm approach I drive the motion with the forearm and you can see that the wrist and forearm are more or less moving together.
