Some people, no matter how much evidence you give them, will refuse to accept the truth set before them.
I've always been fascinated by this silly instrument. It's the perfect intersection of geek and artist, and in a very noli me tangere kinda way. I even had plans (ha ha) to build my own that fell short when my Telefunken catalog did not show up.
(I did get to have a wonderful conversation with Phil York about the theremin back in 2004 and I wish I had recorded it. If you have a time machine, please contact me.)
But, with this odd instrument in mind, here's some fun videos that explain why this is so great.
This is where most people know that sound from.
Jerry Lewis, easily confused.
Clara Rockmore, whose fingering technique is still in use today.
Other techniques get you a different sound.
It also helps if you TURN IT ON.
I'm not even going to get into the daxophone or waterphone, but I should.
