Thanks for filming! In general, this looks fine.
I’d point out that your faster motion is a single-escape / aka “pickslanting” motion, but the slower notes in this clip are double escape, and it’s not clear if that’s the efficient kind of double escape motion that can also go fast, or the stringhoppy kind that tops out. Great players like Andy Wood exhibit the same tendency, where their slower form is double escape and possibly not even the efficient kind:
…while his faster form simplifies and becomes more obviously single-escape:
This doesn’t matter in Andy’s case because if you run through these clips “warp1”, “warp2”, and so on, you can see that he transitions smoothly and subconsciously to the straighter-line motion when speeding up. And if you ask him to play phrases that would actually require some other combination of motions beyond single escape, then he has ways of doing that too which aren’t always easy to describe in simple terms. If you watch clips like this one in slow motion, for example, you’ll see all sorts of combinations, as some of his motions appear single-escape, and some appear double:
So he gets it done, one way or another! Where this becomes problematic is when we see clips of players who haven’t learned the single-escape motion at all, and don’t make the transition. These are the players who complain of a speed limit, and nine times out of ten, when we look at their playing, what we see is the double escape motion that never transitions.
So you’ve passed that hurdle and again this looks fine. If you feel like some aspect of smoothness or speed is still missing, and you’d like to experiment with other motions, I’d recommend extending the fingers and in your grip and allowing them to graze the guitar body. If you try to execute the exact same motion you’re doing here, you may find that this alteration subconcsiously triggers more forearm activation, and feels a little different. If you want to try and do this consciously, you can deliberately give some of these a try:
Otherwise, I’d move right along to playing longer, single-escape musical phrases that utilize the motion you’re using here because it seems to be working as intended. I wouldn’t worry at all about hitting super high upper limit speeds because you’ve already passed the glass ceiling (i.e. the transition from stringhopping) that stops most people.
Good work.
