The pulse level in music is often described as a series of isochronous beats that provides an underlying reference structure against which we perceive rhythmic patterns. This notion is challenged by music styles that seem to feature an underlying reference structure that consists of beats of uneven duration, such as certain traditional Scandinavian dance music genres in so-called asymmetrical meter . This study investigates periodic body motion as a reference structure in a specific style of traditional Norwegian dance music called telespringar . The intimate relationship between music and motion is often highlighted in rhythm studies of telespringar, so this study encompasses both sound and motion analyses. It is based on a motion capture study of three telespringar performers; one fiddler and two dancers. Motion analysis of the fiddler's foot stamping indicates a stable long–medium–short duration pattern at beat level. Motion analysis of the dancers' vertical motion of the hips revealed a periodic pattern in synchrony with the beat duration pattern determined by the fiddler's foot stamping. This result implies that the underlying rhythmic structures in telespringar depend upon a shared and embodied knowledge of the underlying asymmetrical reference structure that is implicit in the production and perception of telespringar.

研究周期性身体运动作为挪威遥游表演中的默认参考结构

音乐中的脉搏电平通常被描述为一系列同步拍子，这些拍子提供了一个基础参考结构，我们可以据此感知节奏模式。这个概念受到音乐风格的挑战，这些音乐风格似乎具有由参差不齐的拍子构成的基本参考结构，例如某些所谓的不对称音高的传统斯堪的纳维亚舞蹈音乐流派。这项研究调查周期性身体运动作为参考结构的一种特定形式的传统挪威舞蹈音乐称为弹簧跳。音乐和动作之间的亲密关系经常在远距弹跳的节奏研究中得到强调，因此该研究涵盖了声音和动作分析。它基于对三个弹性弹簧表演者的运动捕捉研究；一位提琴手和两名舞者。提琴手的动作分析 踩踏表明节拍水平上稳定的长－中－短持续时间模式。对舞者臀部垂直运动的运动分析显示出一种周期性的模式，与提琴手的脚踩踩踏所确定的节拍持续时间模式同步。该结果表明，遥簧的潜在节律结构取决于对潜簧的产生和感知所隐含的潜在的非对称参考结构的共享和体现的知识。
