Descending dsx palm/heel

Playing Technique
#1

here’s the problem: when I ascend a minor pent scale with usx, the palm/heel of my hand glides gently across the bridge as I track across the strings - which I think helps as a dynamic kind of anchor, but when I descend using dsx my palm/heel falls off the bridge (around the time I hit the D, A, and low E strings) and my clean, 90 degree pick slant goes to heck. And this is when I’m sitting down. when I stand and play it’s a whole new can of worms! Is it as simple as remembering to lift my hand a little when I get down there or am I doing something wrong?

(TLDR: it looks like I’m string hopping, but only descending the lower 3 strings for some reason)

Why would you invert your picking motion to descend?

#3

I’d like to keep it strict alternate picking. no legato or adding a 3 note to maintain slant. strict 2 notes per string up and down.

#4

It sounds like a lot of effort for a small gain but I am curious to see how you are approaching that transition. Care to share a video?

I’ll see if I can film a good angle; Genuine question - are there professional players who use strict alternate picking and if so why would you change their technique?
