    Hello,

    The circuit you show is basicaly a beat oscillator.
    It will produce a tone that is the difference between the two oscillators.

    A real theremin consists of 4 oscillators.
    2 are used for the pitch and 2 are used for the volume.

    On the following page, you will find some links to some "real" theremin schematics:

    Hello,

    A Theremin is a musical instrument that is played by moving you hands.
    The sound is a bit like a violin.
    Here are a couple of videos where the Theremin is played:
