FretNot Adam Kumpf, Hiroshi Ishii

FretNot is an exhibition to study the effects of physical constraints on musical composition and improvisation.

Three guitars with unique fretboards are used for comparison; fretless, chromatically fretted, and fret-limited (only notes in a particular key sound). Two non-physical constraints can also be switched on by the user to provide background audio containing a rhythm track (temporal constraint) and a chord accompaniment track (tonal constraint).
