The Theremin has a very distinct and beautiful sound, it's ashamed that it's not used more by modern composers. One reason for it's being little used might be that it's very expensive to buy and excruciatingly difficult to play. The player needs to have perfect pitch because there are no reference points to put your finger on to get your bearings, your hands are just waving around in the air. I'm definitely going to get more Theremin DCs.
