Relay organ plays the sound of switching

Youtuber ffoitl shares this refreshing take on the MIDI synthesizer, utilizing the acoustic side effects of a relay switch –

a musical instrument inspired by elisha gray’s “musical telgraph” one of the first electric/electronic musical instruments ever.

the sound is recorded with a self-built piezo contact mic and a coil taken from a solenoid.

Cited as inspiration, Elisha Gray‘s invention is acknowledged as the first electric synthesizer –
