Abstrakt: In Carnatic music concerts, taniāvartanam is a solo percussion segment that showcases intricate and elaborate extempore rhythmic evolution through a series of homogeneous sections with shared rhythmic characteristics. While taniāvartanam segments have been segmented from concerts earlier, no effort has been made to analyze these percussion segments. This paper attempts to further segment the taniāvartanam portion into musically meaningful segments. A taniāvartanam segment consists of an abhiprāya, where artists show their prowess at extempore enunciation of percussion stroke segments, followed by an optional korapu, where each artist challenges the other, and concluding with mohra and korvai, each with its own nuances. This work helps obtain a comprehensive musical description of the taniāvartanam in Carnatic concerts. However, analysis is complicated owing to a plethora of tāla and nad. e. The segmentation of a taniāvartanam section can be used for further analysis, such as stroke sequence recognition, and help find relations between different learning schools. The study uses 12 hours of taniāvartanam segments consisting of four tāla-s and five nad. e-s for analysis and achieves 0.85 F1-score in the segmentation task. [ABSTRACT FROM AUTHOR]
