About the Theremin

What is this?

A touch-controlled frequency generator inspired by the original theremin instrument. Move your finger across the pad to control pitch and volume simultaneously, creating smooth, expressive sounds through your Tesla coil.

How to play

Touch the pad and move horizontally to change pitch (left = low, right = high) and vertically to change volume (bottom = quiet, top = loud). The frequency display shows your current note in real-time.

Musical expression

Unlike stepped instruments like keyboards, the theremin gives you continuous pitch control — perfect for creating eerie glissando effects and smooth note transitions through lightning arcs.
