For emotional communication by improvisation, happiness was conveyed most successfully when snare drum was used, but sadness was well conveyed when keyboard was used. Which factor causes the dissonance, the timbre (percussive timbre vs. piano) or physical property of the instruments (played with sticks vs. fingers)? We conducted an experiment using MIDI keyboard with percussive timbre. Thirty-nine participants made an emotion detection task for recorded improvisations, which expressed happiness, sadness, anger, fear, and no emotion. The results showed that happiness was conveyed most successfully. It is suggested that emotional communication by improvisation depended on timbre rather than physical property of instruments.
