I saw a few of your videos on youtube. It is so nice to see a teacher
willing to share their techniques, thoughts etc.
I noticed in a few of your videos you talk about faster passages being
played with a thumb/index finger movement and then show that technique while
playing slower. You described it as an artist drawing which I understand.
I could not help but notice that it appears that as you increase the speed
of your playing your thumb becomes stable and your pick movement no longer involves finger movement. Is that correct?
To me it makes sense that only the fingers or the wrist/elbow could produce fast precise picking at any given time and not a combination of the fingers and wrist/elbow since they do not allow for movement on a similar plane because they
allow movement on almost perpendicular planes in the picking positions shown.
The fingers moving the pick could be assisted by the shoulder (since they can produce same plane movement) to aid in picking but that would defeat the purpose of using fine motor skills to pick and would be like trying to draw with your shoulder aiding your fingers. The increased lever length results in less control at the point of contact and therefore a sloppy & inaccurate drawing.
When playing several different passages I can understand how some can be played using different techniques. Can you clarify what technique you use for extremely fast & accurate note sequences?
