1) Do you sit or stand while playing?
At home, I sit - for stability. I stand when I play it in public, for visual effect!
2) Your pitch and volume techniques: Do you use a fingering technique similar to anyone else? Do you move your body toward the pitch antenna or just use arm and finger movements?
I have come from a lifetime of playing slide guitar - I use whole-arm movements and micro-corrections with my wrist. I correct in real time, without noticing I'm doing it.
Often I'll play on the UNDERSIDE of the volume antenna, with a wrist movement.
It's more like depressing a key or plucking a string...
I tried finger-position playing for a while. It seemed dependent on knowing the exact notes I was going to execute ahead of time - great for if you're sight-reading or playing an intricate set piece from memory, less useful for improvisation. It didn't suit me (reminded me of piano fingering...) and wasn't as much fun as carving melodies out of air with my arm.
3) How do you like your pitch linearity: non-linear like a stringed instrument or linear like a keyboard? Do you like wide octave intervals that require some arm movement, or octave intervals within the reach of finger and wrist movements?
I started on a hilariously non-linear theremin, but had no difficulty learning the pitch field.
Then I got a Theremin Uno - which has linearity programmed into the firmware.
It's less of a struggle.
4) What insights do you think you have developed in your playing? I'm talking about perhaps subtle or even subconscious things that are deeper than the simple mechanical fundamentals.
The theremin is a cruel barometer of your physical condition. If your stance is shaky, or your muscles are stiff, an involuntary low-level random vibrato will sabotage everything you attempt.
5) What recurring difficulties do you have, such as pitch wandering, overshoot/undershoot, coordinating volume and pitch, etc.
If I don't limber-up before I start playing, it's agony to listen to and disappointing to experience.
Hungover and dehydrated makes for a rusty performance.
Stoned - with "elastic" low muscle tone - is a non-starter ;-)
6) Approximately how long have you been playing the theremin?
Actual heterodyning theremin? Since 2013.
Feels longer than that.
I built a photocell-controlled audio oscillator in 1978.
3 centimetres of pitch range (linearity was NOT a consideration) ...
7) Do you play other instruments? Have you had musical training? Again, don't be humble.
45 years of guitar and bass. I also play keyboards, harmonica, cello and trombone.
I've studied & practiced long and hard, but never with a institution.
I don't need a diploma to play the music I want to.
8) What kind of music do you play? What motivates you?
Psychedelic rock, mostly.
But - on theremin (and any other monophonic instrument) - anything with a strong melody is fair game.
1960s pop, TV Themes... Hard Rock riffs are hilarious.
Motivation:
I come from an Electronics background and was initially interested in solving the many irregularities of a "classical" analogue theremin. I soon discovered that is an endless and hard-won field of endeavour. Playing music is a lot more fun...
9) Anything else that you have to say about playing the theremin.
I play "left-handed", in that I execute pitch with my left hand and articulate notes with my right hand (The same is true of my Trombone playing).
I wasted 3 weeks trying to play the theremin like everybody else.
When I turned the thing around 180 degrees, the muscle memory and brain specialisation from playing the guitar kicked in and things became effortless.
I rarely use effects. I had expected to use delay and reverb far more than I do.
In a Rock context, POSSESSION of a theremin is 90% of the battle. One night, due to a missing band member, I got stuck playing Bass for a whole gig, so my singer "played" theremin by throwing wild shapes and dancing near it. The effect - for the audience - was pretty much the same as for my measured and intonated performance. Humbling...
Urs Gaudenz played a masterstroke - the Theremin Uno is ideal for me. It automatically tunes Zero Beat and Zero Volume to my current position, every time I switch it on, and gives me consistent results.
Because it's Open Source, I've hacked the firmware to get Tremolo, Pitch Quantisation (which is a lot less useful than you'd imagine) and the Wavetables in an order that I think is logical (I must get around to adding LEDs to indicate the current state of the controls...).
Any complaints about the tone are moot points to me:
It doesn't shift waveshape as you travel through the pitch spectrum?
So what!
I don't subscribe to any orthodoxy and I'm not aiming to emulate any "classic" tone.
I'm delighted to have found a piece of musical gear that I don't feel any need to trade in for something New and Improved.
Theremin World has been educational in a whole lot of ways.
