From the OHMI website: One-Handed Musical Instruments
There is presently no orchestral musical instrument that can be played with one hand. Any deficiency in one hand or arm makes traditional instruments unplayable to any reasonable standard. As a result hundreds of thousands of people with disabilities in the UK, and millions across the world, are excluded from music making.
THE COMPETITION: The OHMI Trust is challenging technologists, inventors, instrument makers, and anyone else who would like to have a go, to design and build one-handed instruments that can emulate any of those used in the classical orchestra. The best will be awarded the world’s most prestigious prize for creative technology, a Prix Ars Electronica.
Judging of the 2013 competition entries took place on July 24 in London at the Associated Board of the Royal Schools of Music. The judges were Alison Balsom, Peter Purgathofer, Nigel Scaife and Doug Bott.
