本研究では、ライヴ音楽演奏における表現者と鑑賞者の心の動きの時間的同調性を明らかにすること目的として、アコースティック弾き語り形式の音楽ライブ実験を実施し、現地・遠隔会場における鑑賞者の心拍数と主観的な感動度および演奏者の心拍数を計測評価した。実験の結果、音楽ライヴの演奏者―鑑賞者間の心拍数については時間的同調性がみられない一方で、演奏者の心拍数と鑑賞者の主観的感動度には時間的同調性がみられることが明らかとなった。これらの結果から、表現者の心拍反応は、鑑賞者の心拍反応と必ずしも時間的に同調しないが、鑑賞者の主観的感動度は、表現者に生じる心拍反応と時間的に同調する可能性が示唆される。
This study aimed to elucidate the temporal synchrony of psychophysiological responses between performers and audiences by conducting an acoustic live music experiment. The heart rates and subjective levels of emotional impact of the audience in both on-site and remote locations, as well as the heart rates of the performers, were measured and evaluated from the point of view of temporal synchrony. We found that while there was no significant temporal synchrony in heart rates between performers and audience members during the live music performance in both on-site and remote locations, there was significant temporal synchrony between the performers' heart rates and the audience's subjective emotional impact. These results suggest that although the heart rate responses of performers do not necessarily synchronize with those of the audience, the audience's subjective emotional impact may synchronize with the heart rate responses of the performers.
