An experiment has been conducted, measuring pianists’ sensitivity to piano key vibrations at the fingers while playing an upright or a grand Yamaha Disklavier piano. At each trial, which consisted in playing loud and long A notes across the whole keyboard, vibrations were either present or absent through setting the Disklavier pianos to normal or quiet mode. Sound feedback was always provided by a MIDI controlled piano synthesizer via isolating ear/headphones, which masked the acoustic sound in normal mode. In partial disagreement with the existing literature, our results suggest that significant vibrotactile cues are produced in the lower range of the piano keyboard, with perceptual cut-off around the middle octave. Possible psychophysical mechanisms supporting the existence of such cues are additionally discussed.

Perception of interactive vibrotactile cues on the acoustic grand and upright piano

Abstract

An experiment has been conducted, measuring pianists’ sensitivity to piano key vibrations at the fingers while playing an upright or a grand Yamaha Disklavier piano. At each trial, which consisted in playing loud and long A notes across the whole keyboard, vibrations were either present or absent through setting the Disklavier pianos to normal or quiet mode. Sound feedback was always provided by a MIDI controlled piano synthesizer via isolating ear/headphones, which masked the acoustic sound in normal mode. In partial disagreement with the existing literature, our results suggest that significant vibrotactile cues are produced in the lower range of the piano keyboard, with perceptual cut-off around the middle octave. Possible psychophysical mechanisms supporting the existence of such cues are additionally discussed.
