Every year around March, the Georgia Institute of Technology in Atlanta, USA, puts on the Margaret Guthman Musical Instrument Competition.
Every year more and more artists challenge the notion of traditional instruments, and invite us to imagine ways that music will be made in the future. Acoustic instruments are pulled apart and put back together with used parts from just about everything. Circuits are bent, sensors are sown onto clothes, and code is scrupulously written and rewritten.
The results are new sounds, new ways of visualising them, and new ways of physically controlling them. Not sure how the judges can decide on a winner, though, with all these great entries.
