摘要
Raga recognition in Hindustani classical music is difficult because a raga is not defined only by the notes used in it. Its identity also depends on the way notes are emphasized, the movement between notes and characteristic phrases. In this work, we develop a computational approach to analyse these characteristics directly from audio recordings. The method uses pitch extracted from recordings and represents it using a 44-position note framework based on the 22-shruti system. From this representation, Raga features based on the Indian classical musicology are extracted.Each feature is compared with a reference representation of the raga and the resulting scores are combined to obtain an overall similarity score. The method is first studied using Raga Yaman and is then tested on recordings of other ragas. The computational results are also compared with the theoretical description of Yaman to identify which raga characteristics are captured well and where the method has limitations.
