Fair enough.
I may have understood your intention, based on the original post in your earlier topic.
I didn’t think you held either position.
For whatever reason, there are people who strongly believe that thumb/finger movement as a primary picking mechanic carries some uniquely special advantage over other joint motions (though they never explicitly state what that special advantage actually is). Some will even tell you that it’s an essential component of picking technique.
Recently a Pebber Brown video came up in my YouTube recommendations, where he was discussing “scalpel” and “sarod” picking.
After a backhanded compliment towards @Troy and a (ridiculous) criticism of Brazilian Jiu-Jitsu, Pebber goes on to say that without finger/thumb movement, you’re limited to “adjacent scale-tone soloing.” He ascribes thumb/finger movements to players who really do not (or did not) ever use it to support his argument.
I don’t want to single out Pebber here, there’s an enormous amount of misinformation out there, he was hardly the worst offender and likely mislead himself. Despite having said in interviews that his picking technique was inspired by sarod players, John McLaughlin’s technique isn’t anything like a sarod player or an oud player. Typically, neither sarod nor oud technique makes use of the thumb/finger movement that Pebber describes. Both sarod and oud are typically USX wrist/foream mechanics from a flexed wrist position, most similar to gypsy technique.
It’s difficult to have any meaningful conversation about the role of thumb/finger movement in picking technique without getting derailed by this type of misinformation. Whether we call it “circle” picking or “scalpel” picking or whatever else, we’re going to have to free ourselves from this type of misinformation if we hope to develop a genuine understanding of thumb/finger mechanics.
Worse still, in some discussions thumb/finger movement almost becomes “the God of the gaps,” an almost supernatural unseen force that accounts for everything we don’t yet fully understand without explanation. I don’t want to leave those gaps.
This has become a particular bugbear of mine in the last twenty years of posting on guitar forums, and my rant here is probably an overreaction.
It’s worth mentioning too that the volcano 6-note pattern is an efficient digital cycle, as I’ve defined it previously on the forum.
That’s totally understandable. Also (and not saying you implied it), “it’ll never work” is not a fair summary of my current position, and it was most certainly not my first resort.
I’m not any kind of authority on drumming technique, but my father is an excellent drummer and I’ve been watching him play my entire life. It’s really something to see this double-stroke mechanic and Moeller trips/quads being executed.
I think the natural compatibility between the movements is very interesting. From an American grip, the first hit is like the dart-thrower downstroke. The fingers naturally open during ulnar flexion to relieve the stretch on the extensors (like when dribbling a basketball), and the fast flexion of the fingers naturally assist the return to radial extension. The dart-thrower muscles (flexor carpi ulnaris and extensor carpis radialis and brevis) also have secondary function in elbow flexion. All of the joint movements seem to work synergistically in a manner determined by the functions of the muscles involved.
I often include a hybrid picked note with the middle finger after an upstroke when playing with the Shawn Lane style dart-thrower movement. This feels very comfortable and easy to do. I think there’s some similarly with the wrist/elbow plus finger action of the double-stroke.
