So how does one go about developing a technique based on the central principle?
The same as what you would do with regular technique.
To be able to utilize the principle, you’ll have to develop the basic techniques first—arpeggios, scales, tremolo.
As you gain proficiency with these techniques, you can begin to integrate the hand by applying a slight pressure to your strokes from the hand.
As you play an arpeggio, pull the hand gently against the strings, feel the slight tension caused by the resistance of the strings, and then release the strings.
The plucking movement is more a consequence of your letting go the string than an actual plucking action.
Instead of four individual fingers plucking the strings, it’s one hand releasing the four fingers in an even sequence.
This may be hard to do at first, because we’ve gotten so used to applying strength in our playing, the idea of releasing power instead may be hard to do at first.
The same thing applies to the tremolo.
For example, an easy way to learn consolidation to gain speed in the tremolo is to place the three fingers, i, m, a, on one string.
Then, gently pulling the strings, feeling the resistance in the strings, and then releasing the fingers one by one in a quick sequence.
It’s the same technique as the arpeggio except that you do it on one string.
In scale playing, the central principle works especially well with descending scales for obvious reasons, but it’s also highly effective in ascending scales.
The key thing is to feel a slight pressure in every note, and then release the string. The release should be a complete letting go.
This is the crucial factor.
The central principle is based on releasing tension.
First, you generate tension by applying pressure to the string, you respond to the resistance in the string, and then you let go.
This goes back to the principle of release in the AOV.
To generate speed and power, concentrate on releasing tension, not applying force.
