A gestural autoharp that functions as a class-compliant USB MIDI controller instrument.
Originally conceived in 2010, the AirHarp is a gestural autoharp that allows the musician to strum chords on an invisible beam of ultrasound. For several years, I manufactured and sold these musical instruments online. The entire project is open source. If you build one, please send me a note! I'd love to see it.
Cheers,
