So I’ve had a minor setback – or a discovery – depending on how you look at it.
Since trying to learn these new motions, I’ve started to feel some pain in the right (picking) arm shoulder. This has led my to try and see if I could provoke the discomfort – if I could do motions that would make it more uncomfortable! And then, of course, try to avoid doing that!
I’ve found something, that couldn’t be seen from a magnet point of view. The error on my part, comes from trying to rest the side of the hand on the bridge – and trying real hard to have the side of the hand as straight as the bridge. This lead to the wrist being in a state of extension, while trying to perform the motions neccecary to picking the notes.
Doing wrist extension away from the guitar gives the same kind of pain in the shoulder region as when I try to maintain that position on the bridge of the guitar.
A more relaxed position gives the side of the hand a more oblique line in relation to the brigde and no more pain from extending the wrist.
I don’t have a picture of it here, but when the hand goes towards the strings with a pick, it places the pick where the middle pickup is on a strat. The position in the first picture would position the pick between the bridge and the middle pickup.
Another issue I am investigating is radial deviation when doing upstrokes/going to a lower string. I suspect that I am not doing enough “motorcycle throttling” (I remember hearing this term in a crosspicking video – is it still a thing or is it passé?) with the wrist, instead trying to reach the lower string by doing more radial deviation – going passed the zone of comfort.
I am also going to try to experiment with a more supinated arm position, to see if that works better for me.
Finally, the downward pressure of the hand on the bridge to keep it in place. I don’t want the hand and/or the guitar to move around too much, so that I don’t have a sense of where the pick is in relation to the strings, but I think maybe I am putting too much pressure on the bridge. Pressing hard seem to activate pain/irritation in the shoulder region.
