The more I have practiced I am becoming convinced that use of a back-handed (note -- see my posting on 12/18/2005 -- it is not really a backhanded technique) technique yields the greatest accuracy. Here are some notes:
~~ stress, pain, and arm position ~~
At first, I was playing with my hand in a somewhat low position -- holding it about even with the bottom of my ribcage and with a relatively low height adjustment on my Theremin. This worked well however to to turn my hand such that my knuckles were in a vertical position really causes stress, particularly when adding some vibrato. While I could accurately navigate first and second position it was just too stressful (too much twisting of the wrist).
However, revisted the Pringle DVD and the Kurstin DVD and noticed that they hold their hands higher -- almost up to shoulder height. The fingertips point more "up" than "out". Well, I found in holding my arm in this position that a backhanded (note -- a little backhanded however I added a disclaimer above) hand position results without twisting the wrist.
Also, the knuckle extensions as described by Peter Pringle work well from this position.
~~ back to the Pringle gliss ~~
I have just about got this... I am positioning my hand a 3rd below the target note and then using knuckle extensions to reach to third position. The "gliss" is not really a smooth slide -- it is almost like a few separate notes -- a "mini scale" leading up to the target note. The vibrato heightens the effect. Of course, Peter backs off the volume antenna just enough that the gliss is not overdone. It is a subtle shade... too little volume and the gliss disappears -- too much and well... it starts to sound a little "over the top"!
Peter always does this upward. To do it downward is well... uh... even more over the top! (Well worth a try). Sometimes we "milk" a phrase a little, sometimes a lot!
