The Flote is a wind instrument designed for people with limited mobility. Past work in this area has failed to deliver the musical expressiveness expected of an instrument while maintaining the low cost required for wide adoption. Using only head movement and breath control, both calibrated to match the player's abilities, the Flote is an avenue for creative expression and an enjoyable form of physical therapy. The software is available as a free download at http://www.theflote.com, and the hardware can be easily built by anyone with minimal familiarity with circuits.
