The normalised pairwise variability index (nPVI), has been frequently used to measure the rhythmic variance between musical onsets. For example, researchers have proposed connections between the nationalities of composers and the nPVI values of their music and native language. One particular issue, however, lies in the notion of intended nationality – composers frequently wrote in national styles other than their own. This study employs the RISM-World dataset to both replicate previous findings relating the rhythmic variance of melodies to the nationalities of composers, and to examine intended nationality in the music of Mozart and Handel, namely their operas and oratorios.

节奏变异性、语言和风格：nPVI 发现与 RISM 数据集的复制和扩展

归一化成对变异指数 (nPVI) 经常用于测量音乐开始之间的节奏差异。例如，研究人员提出了作曲家的国籍与其音乐和母语的 nPVI 值之间的联系。然而，一个特殊的问题在于预期国籍的概念——作曲家经常以不同于他们自己的民族风格写作。本研究使用 RISM-World 数据集来复制先前有关旋律节奏变化与作曲家国籍的发现，并检查莫扎特和亨德尔音乐中的预期国籍，即他们的歌剧和清唱剧。
