Aids in projection of sound. It carries the sound out towards the listeners
Aids in relaxation. After you pluck, immediately relax as you raise. You will condition yourself to relax every time you raise.
Raising is an extension of the phrase and will help shape the phrase.
Raising can aid in the rhythmic sense. Train yourself to raise rhythmically and it will continue to solidify your rhythmic understanding. For instance, if you play consecutive half notes, raise up and away for one beat, and down towards the next placement for the second beat.
Make the raise one smooth motion. Don’t stop mid-air. Treat it as if you are painting the sky with the color of the phrase, and your arm is the paintbrush.
Raising is aesthetically pleasing. It will look appealing to your audience and show them that you have put great care into the phrasing and musical expression
Pretend there is string attached to your knuckles. The second you are finished plucking, imagine that string being pulled up and away from the instrument. You raise FROM the knuckles, not from any other part of your hand or arm. – – – Lead with the knuckles and pivot from the elbow.
Raise near the strings you have played. Don’t raise towards the column, or toward yourself UNLESS you are replacing in that direction. Raise up and away from where you just played, and towards the next placement.
Maintain relaxation throughout. Don’t feel any tension in your arms or hands as you are raising.
Breathe through the phrase, and relax the muscles.
