Extremely honored to perform the revised version of the 8 Sketches for One Pianist and Disklavier within a research project of CITAR and a new Sketch Reflections (2012) by Jean-Claude Risset dedicated to me in a World premiere in the closing ceremony of Black&White 2012 Film Festival promoted by the Catholic University of Portugal. Several issues on the performance of this work are analysed as a casestudy, from the point of view of the performer, particularly the components of expressive performance in a real-time interaction between performer and computer. These components can work as analysis criteria of a piano interpretation, in here, of a pianist and Disklavier interpretation.engDuet for one pianistJean Claude RissetDisklavierReal-time interaction performer and computerComputer-aided compositionHuman-computer interactionjournal article10.7559/citarj.v6i2.115
