The Multi-Tuned Piano: Keyboard Music Without A Tuning System

A physical synthesis instrument, such as one of Pianoteq's series of grand pianos, unlike a physical grand piano, is not necessarily constrained at any moment to a single tuning system. The article discusses why a system using discrete piano pitches (not sliding pitches) chosen freely amongst the audible pitch continuum presents interesting musical and expressive possibilities. Audio and video of compositions and an improvisation exploiting the system demonstrate its potential and a performing interface for it.
