So it's time to start figuring out what works for scoring for theremin and orchestra and what doesn't - as my main goal is to write music for the instrument, not become a professional thereminist. But you have to have a good idea of how to play any instrument to write effectively for it.
Wrote this short piece to start testing things out in preparation for writing a much longer piece for theremin and orchestra (I'm thinking a tone poem of some sort as opposed to a concerto that I think would pose some significant problems). Been working on a Klezmer Suite that's in a very accessible tonal style for a long time and never came up with a slow movement I liked and thought hey something for theremin and orchestra might be nice (though a violin could be substituted).
Pavanish for Theremin and Orchestra
See below for score, parts and accompaniment.
As I wrote this piece experimenting with different ranges of the theremin (I tried all few theremins I have) against the orchestra (of course MIDI sampled orchestra here) I found a few things. I'm sure others have talked about similar issues. This is my initial take which is at this point centered on melodic playing (not using the theremin for effects against the orchestra, possibly with effects pedals, which is a totally different area to discuss). Others may disagree with me here. That's fine.
1. You have to be very careful in your scoring. It's very unlike most solo instruments. The theremin really doesn't blend in that well to my ear or it can create a muffling effect. You can't get in its way. In fact I had to reduce the orchestra's size here from the original. I might use a large orchestra, but likely not that much tutti when the theremin is playing. In many ways the theremin is ideally a chamber instrument in my mind. I fear, if you have to crank it up to a deafening roar to get above the full orchestra you are going to hurt your poor audience. I still have a lot of experimenting to do with volume and levels - and also the bass as I was told has too much low energy in the pizz if a sub-woofer is being used (tried EQing that back - but need to hook up a sub-woofer). This is an interesting by-product of creating sound files - you really have to test anything you do with a variety of speakers from good to crappy.
2. Keeping with the above, try not to have counter melodies in the range of the theremin. Sounds better when your counterpoint is in another register. I have some oboe against the theremin too close in range in here that just didn't blend the way I wanted, but the lower clarinet sounded better against the theremin to my ear.
3. As I've seen somewhere else, doubling the theremin with other instruments doesn't sound too great in many cases. Again, to my ears, its not a blending instrument.
4. You can have the theremin as an accompaniment/counterpoint to your orchestra if you get it out of the way (i.e. stick it up high).
5. Low range of the theremin really needs to have the orchestra tone way, way back. Need to experiment with the theremin on the bottom and orchestra all above it. That might be a nice effect.
6. In general (at least on my few theremins) I've seen that almost all the volume variation in terms of getting a highly expressive dynamic line happens within only a scant 1-3 inches (sometimes less) from the antenna. The theremin can get loud quickly so the orchestra needs to be playing very softly to bring out the expressiveness of the theremin (or as noted above reduce the orchestra in texture). Bernard Herman's great score to "The Day the Earth Stood Still" was really very limited in instrumentation, but in my mind one of the best compositions for theremin and "orchestra" ever written.
7. Doubling a melody in some close harmony next to the theremin has some issues as well. Sounds better if you have two theremins in that vein or double in another octave. I thought a flute which is more sine-like might harmonize well, but I didn't really like it and actually removed the flutes altogether from the piece as it cluttered the texture against the theremin. Need to do more experimentation there.
8. That theremin is really a solo instrument and not one that really should be playing all that loud for any extended period of time. Your ear can easily center on it and lose track of the orchestra I've found.
9. Less is more. Don't let the theremin play for too long. Mix it up with the orchestra. My ear can tire quickly of the theremin sound so let the orchestra do a lot of the heavy work.
10. Playing long notes above the orchestra works well.
11. Horns sound good as accompaniment (as horns always do). Not sure about other brass. Didn't use anything but horns here. Need to experiment a bit there.
12. Same for percussion. I think a piece for just percussion and theremin might be really nice. Need some experimenting there.
Well on to more orchestral tests. My goal here is to put together a chapter on scoring for the theremin that could be used in conjunction with one of the many orchestration texts available that don't even mention the instrument. Maybe some newer ones do. I'll post that as a "book" on IMSLP with some examples as that is the better forum to post a thing like that for mass consumption. Of course I can only use my music and public domain music for examples.

P.S. - Just uploaded a new version of the score, complete parts (see Parts tab) and a .MP3 file of just the accompaniment (Synthesized/MIDI tab) if you would like to try and play along. Might take a day for IMSLP to vet this an make it available. The piece is submitted under a Non-Commercial Common Copyright licence which means anyone can use it for any purpose they like as long as they are not trying to make a commercial profit from it without my permission.
