I was looking over a few Claus Levin videos last night where he casually mentions “pick depth”, as in how much of the plectrum is used to actually pluck the string. He goes into little detail about this, but just mentions achieving an even resistance on both your down and up strokes.
For such a small and simple detail, I have discovered this to be quite profound, and immediately noticed inconsistencies in my own picking depth, which I believe have been subtly contributing to tension and holding my picking hand back from developing dexterity.
On top of this, I have found over time that my picking hand can only execute tremolo picking of a decent speed when placed in a strong upward pick slanting direction, with the thumb/palm area anchoring on the lower strings or the body of the guitar. I now realise that the reason this is effective for me, is because it puts my picking in an advantageous position to achieve a shallow and even picking depth.
It’s amazing how quickly you can adapt after becoming aware of these small points of attention.
Has anyone else had any findings in this particular area?
