Title: The Asymmetrical Influence of Timing Asynchrony of Bass Guitar and Drum Sounds on Groove

Journal(書誌情報):Music Perception: An Interdisciplinary Journal, Vol. 34 No. 2, December 2016; pp. 123-131.



Abstract: Groove is a pleasant feeling that compels people to move their bodies along with music. In the past, there was some consensus among both musicians and researchers that the main factor in inducing this feeling is onset asynchrony of sounds. However, recent studies have asserted that no-asynchrony is the condition that will obtain the highest groove. The current study examined whether no-asynchrony exclusively elicits the highest groove. In Experiment 1, we measured the groove increment of a backbeat drum pattern as a function of the asynchronies between bass guitar and hi-hat cymbal sounds. Upon evaluation, the scores of no conditions exceeded those of the synchronous condition. However, the condition with slight bass guitar precedence over the hi-hat achieved an approximately equal score to the condition with complete synchrony, and that score was higher than the ones achieved with bass delay. In Experiment 2, we measured the participants’ sensitivities to timing

discrimination. The results confirmed that the amount of bass precedence in Experiment 1 was perceptible to the listeners. These findings suggest that complete synchronization is not always the best condition to achieve groove and that listeners prefer perceivable asynchronies in some cases.

日本語によるコメント: 本研究は,「音楽のグルーヴ感(音楽に合わせて体を動かしたくなる感覚)を最大にするためには複数楽器間の発音タイミングが一致している方が良いのか,ややズレている方が良いのか」,という議論に対して,心理物理学的手法でアプローチしました。結論は,「ズレはそれだけでグルーヴを明確に増幅するものではなさそうだが,ズレている条件が好ましい場合もある」,というやや折衷的なものになりました。(松下)
