> There are also a surprising number of well-known pop (etc.) songs that include a theremin somewhere.

There are definitely some strong uses of theremin in there, but after sampling a few I also found some that I don’t think are theremin at all, which makes me wonder if that’s a common theme - whether a good chunk of that list isn’t theremin, but other instruments.

For example, Wonderboy (Tenacious D) seems to be using a synth with portamento (aka glide), which is pretty common and does sound a little like theremin while the pitch is sliding, but ultimately gives a very different effect, mostly because when it reaches the target note, it holds the note strongly. Theremin’s effect tends to be disorienting because you can’t hold an exact note, so it’s either sliding around or people use a lot of vibrato.

Another one I confirmed is not Theremin is Lovely Head by Goldfrapp. Again, this vaguely sounds like it could be a theremin, but there are plenty of signs it’s either heavily processed and edited, or just not a theremin. My first guess was a guitar under heavy filtering or via MIDI, but then I found this: “ What is often mistaken for a theremin synth in the song is, in fact, Alison's vocals manipulated through a Korg MS-20 synthesiser.” https://en.wikipedia.org/wiki/Lovely_Head
