Online theremin: play without touching
The theremin is the eerie electronic instrument you play without touching it, heard in old science-fiction films. On a real one, one hand controls pitch and the other controls volume.
Here your mouse does both: move it sideways to change pitch and up or down to change volume. Adjust sensitivity to make the range wider or narrower.
How to play the theremin with your mouse or touchscreen
- Move the mouse left and right over the playing area to change pitch.
- Move it up and down to change the volume.
- Use the sensitivity control to set the pitch range.
What you can do on the virtual theremin
- Contactless-style pitch and volume control with the mouse
- Adjustable sensitivity and volume
- Record your playing
