SINGING PENCIL CASE

SINGING PENCIL CASEI propose an extremely simple structure of the electronic musical instrument. Its structure is clear from the drawing and the concept. The musical range of 2-3 octaves.

 
The graphite layer of the resistor R is applied with a pencil. The thickness of the layer is chosen empirically. The game technique is very simple. To play simple melodies after a ten-minute workout. The timbre is reminiscent of performance on stringed or woodwind instruments.
