The Endangered Guitar is a journey through the land of unending sonic operations, an interactive hybrid between a guitar and a computer. The software “listens” to the playing, to then determine the parameters of the live sound processing. 

The guitar is the sound source, but the same sound is also used to control the software. Sounds of the guitar are processed in realtime, pitch and various other parameters of the actual playing serve as control source of the processing.
