分析印度古典唱腔中节奏与旋律的表达差异，构建可区分表演风格的计算模型。
Melodic and Metrical Elements of Expressiveness in Hindustani Vocal Music
- 通过音频处理与标注，量化不同演奏者对同一曲目的时间与音高变化。
- 在两首歌曲、四个拉加、十位艺术家的表演中验证了表达差异的可区分性。
- 适合音乐信息检索与跨文化音乐表达研究者参考。
本文旨在研究北印度克亚尔音乐的美学特征，聚焦艺术家在演绎流行曲目时所展现的灵活性。我们分析了同一歌词内容在不同表演中的表达性节奏与音高变化，并提出了能够区分同一歌曲不同表演风格的计算表征方法。文中介绍了必要的音频处理与标注流程，并基于两位著名艺术家演奏的两首曲目、四个拉加（raga）的表演数据集，讨论了分析结果与洞察。实验表明，表演者的个人表达风格可通过计算模型有效识别。
原文摘要 · Abstract (English)
This paper presents an attempt to study the aesthetics of North Indian Khayal music with reference to the flexibility exercised by artists in performing popular compositions. We study expressive timing and pitch variations of the given lyrical content within and across performances and propose computational representations that can discriminate between different performances of the same song in terms of expression. We present the necessary audio processing and annotation procedures, and discuss our observations and insights from the analysis of a dataset of two songs in two ragas each rendered by ten prominent artists.
