Revenge of the Theremin
It's not just for sci-fi soundtracks anymore

Eight decades after its invention, one of the earliest electronic instruments is popular again.

To play the theremin, a musician's hands hover around the instrument's antennas, controlling pitch and volume by interrupting the electromagnetic fields that surround them.

The theremin produces wavering notes—ooh-WEE—oooh—that sound more like George Jetson than George Gershwin. You may have heard it in Led Zeppelin's "Whole Lotta Love." But that's not a theremin in the Beach Boys' "Good Vibrations"; it's the electro-theremin—based on the same principles but laid out like a keyboard.

Remembering which hand position produces what note isn't easy. Inventor Leon Theremin taught the technique in the United States in the 1920s after a series of concerts. He'd already made a splash in his native Soviet Union, giving demonstrations to admirers including Vladimir Lenin.

Build-your-own-theremin kits are now widely available. And Moog Music, a company specializing in electronic instruments, sold more than 3,100 ready-made theremins in 2001. "It's kind of a cult thing," says Moog's Linda Pritchard, "but more people seem to want them every year."
