Abstract The article explores the individual differences of rhythmic variation in traditional sung oral poetry. The analysed group of ritual songs is part of the Seto singing culture – a subtradition of Finnic oral trochaic tetrameter. The rhythmic variation, created by different positioning of stressed syllables in the song line, reveals itself on two levels, in linguistic verse structure and in musical performance. In the singers’ performances the verse and musical structures complement each other, having a cumulative rhythmic effect. By designing the rhythm at both levels, the singers systematically take into consideration the linguistic features of the used words. A statistical analysis shows a remarkable divergence in the rhythmic variation of different lead singers. The results are more homogeneous at the level of linguistic verse structure and more diverse at the level of musical performance. Also, the rhythmic choices of the lead singer and his or her choir in the course of the performance may differ. We may speculate that this divergence in individual rhythmic strategies could have been caused by the singers’ type of creativity and skills, their different perceptions of genre features and intergeneric relations, and the musical influences between more closely related singers.

口头诗歌的个人节奏变化：濑户歌手的Runosong表演

摘要本文探讨了传统歌唱口头诗歌节奏变化的个体差异。经过分析的一组礼节歌曲是濑户歌唱文化的一部分-濑户口头四路测距仪的替代。由重音节在歌曲行中的不同定位所产生的节奏变化，在语言的诗句结构和音乐演奏两个层面上展现了自己。在歌手的表演中，诗歌和音乐结构相互补充，具有累积的节奏效果。通过在两个级别上设计节奏，歌手会系统地考虑所用单词的语言特征。统计分析显示，不同主唱的节奏变化存在显着差异。在语言诗句结构的层面上，结果更为一致，而在音乐演奏层面上，则更为多样。另外，主唱及其合唱团在表演过程中的节奏选择可能会有所不同。我们可能会推测，个人节奏策略上的这种差异可能是由于歌手的创造力和技能类型，他们对流派特征和属间关系的不同理解以及关系更密切的歌手之间的音乐影响所致。
