The document discusses how to play the theremin, an early electronic musical instrument controlled without physical contact. It is played by moving the hands close to two metal antennas, with the left antenna controlling pitch and the right controlling volume. To play a note, the performer brings one hand to within a few inches of the pitch antenna while keeping the other hand farther from the volume antenna.
