I cannot thank each one of you enough for sharing your tips and knowledge on Theremin technique. My playing and confidence has taken quite a jump as I have experimented and applied the tips given.
I am no longer trying the left-right motion thing and, in fact, I am playing with my elbow at my side. In order to reach both antennae I am standing at a slight angle towards the pitch antenna. With a straight-on camera angle, one might get the illusion that I am moving my arm from left to right however I am moving it straight to and from the pitch antenna.
I think Pamelia's DVD may have suffered from that illusion.
To tune now I place my hand in the position that corresponds to "middle-c" for me... that is my pitch arm parallel with the ground and fingers in first position (fingertips resting on the thumb).
From there, I can play up two octaves plus a 4th to F3 and go down two octaves to Low C thus acheiving a 49 note range (that top 4th is not easily playable. To play in the Tenor octave I have the option of moving my hand (and elbow) back OR moving my arm upward in an arc towards my neck (to move to my shoulder introduces stress). As I have experimented with the walking bass playing in the arch -- each note in first position seems SO natural!
Incidentally, this places the zero-beat point slightly behind the front plane of my body -- around 3" -- just that if I rock back slightly I reach zero beat.
Clara Rockmore has scale exercises wherein only first second (and sometimes third) position are used. Going up is a little easier than going down. I found that in going down, I first practice moving downward in thirds in first position. After that, then I start on C3 in first position, then move my thumb down to A while at the same time, opening my hand to second position (resulting in 'B'), then closing to first position for 'A'. It took some practice, however I am able to play good downward scales this way.
It seems that Pamelia is playing her walking bass primarily in first position and inserting the little embelishments by rapid motions to 2nd or 3rd position.
Pamelia even mentioned that one may hit a few wrong notes and that the trick is to 'end up' in the right place -- I guess that means that if you can nail your "target" notes in first position that the fills in between can be a little off!
Anyway, back to the tuning issue...
Having worked this out on the Epro I decided to go back to my Theremax -- and by golly, I was able to use the same procedure for tuning middle C. On the Etherwave I also get a 4 octave + range however the "sweet spot" for easy playing is around 30 to 37 notes -- in the bass and treble the notes are closer together. Also, the Tmax's antenna is more sensitive to up and down motions -- to create a wide vibrato takes less motion on the Tmax than the Epro. I am considering a different pitch antenna on the Tmax to obtain a larger playable range. The Tmax's volume antenna works ok "as is" for me.
The PO was closed today so maybe my Peter Pringle DVD will arrive tommorrow.
As I mentioned, I am standing facing slightly towards the pitch antenna with my left shoulder abeam the center of the volume antenna at a distance that allows me to access the volume antenna without stretching my left arm away from my side.
Which leads to yet another question: How/where do you position yourself at the Theremin?
Sorry for this LONG post. Each and every one of you has already contributed greatly to my (and many others') progress. Thanks again and keep the tips coming!
