ABSTRACT This article presents findings from experiments into piano and live electronics undertaken by the author since early 2007. The use of improvisation has infused every step of the process—both as a methodology to obtain meaningful results using interactive technology and as a way to generate and characterize a collaborative musical space with composers. The technology used has included pre-built MIDI interfaces such as the PianoBar, actuators such as miniature DC motors and sensor interfaces including iCube and the Wii controller. Collaborators have included researchers at the Centre for Digital Music (QMUL), Richard Barrett, Pierre Alexandre Tremblay and Atau Tanaka.
