They say a picture paints a thousand words. If that’s the case, a video should paint 10,000 words.
I shot a simple video with my phone showing the three different ways of plucking—from the knuckle joint, from the middle joint, and with the fingertip.
You can see that in all three plucking methods, all three joints are moving. Our fingers work as a unit, and when we say we are moving from one joint, it doesn’t suggest the other joints are completely stationary.
However, there is a distinct difference in sensation between plucking from the knuckle joint as opposed to plucking from the middle joint as opposed to plucking with the fingertips.
These differences are not psychological, they’re very real. You physically feel one specific joint activating the stroke and the other joints moving in support.
I use all three strokes but my primary and default stroke is the third one, playing with the fingertip, because it is so economical and efficient."
