Abstract: The tendency for groove-based music to induce body
movements has been linked to multiple acoustical factors. However, it
is unclear how or whether tempo affects groove, although tempo
significantly affects other aspects of music perception. To address
this issue, the present study investigated effects of tempo, specific
rhythmic organizations of patterns, and syncopation on groove and the
induction of the sensation of wanting to move. We focused on the
directions of body movement in particular by taking into account nori,
which is an indigenous Japanese musical term used not only
synonymously with groove, but also as a spatial metaphor indicating
vertical or horizontal movement directions. Thus, the present study
explored how groove was felt and defined, as well as how musical
factors induced the sensation of wanting to move in cross-cultural
context. A listening experiment was conducted using drum breaks as
stimuli. Stimuli consisted of various rhythm patterns at six tempi
from 60 to 200 BPM. The main findings are that: (1) an optimal tempo
for groove existed for drum breaks at around 100–120 BPM, (2) an
optimal tempo existed for the sensation of wanting to move the body in
specific directions (i.e., back-and-forth and side-to-side), (3)
groove and nori shared a similar concept of wanting to move but
differed on several points (i.e., association with sense of pulse and
fast tempo). Overall, the present study suggests that there is an
optimal tempo for body movement related to groove. This finding has
implications for the use of music or rhythmic stimuli to induce smooth
motion in rehabilitation, therapy, or dance.

日本語によるコメント（オプション，200-300字で）:音楽を聴いたときに体を動かしたくなる
感覚（グルーヴ）について、テンポとの関係を検討しました。ドラムパターンを刺激とした聴取
実験の結果、以下のことが示唆されました。（１）グルーヴを喚起する最適なテンポが存在する。
（２）体を特定の方向（前後・左右）に動かしたくなる感覚を喚起するのに、最適なテンポが存在
する。（３）グルーヴと日本語のノリには、体を動かしたくなるという共通点と同時に、うねりの
感覚など、差異も存在する。
