Theremin is an electronic musical instrument controlled without physical contact by the performer (who is known as a thereminist). It is named after its inventor, Leon Theremin, who patented the device in 1928.
Theremin is a good old example that was reproduced in arduino using a distance sensor and a note (tone) selector.

This Modulino distance is incredibly precise and works very good for this task.
Using the encoder you can select each note, that can be take a different pitch.
