This is a preliminary study trying to describe the influence of room acoustics on piano performance. Professional pianists were asked to play the same piece in different acoustic conditions. Objective data on musical events were obtained, thanks to the Yamaha Disklavier, an acoustic piano with MIDI input and output. A statistical analysis, updated in real time, has yielded numeric results describing each performance. A preliminary analysis of the differences induced by changes in the acoustics shows which aspects of the performance are affected, and establishes the sensitivity of the produced sound intensity to the acoustic absorption in the room. Further analysis gives more details and allow to propose a model for the phenomenon.
