A Survey on Computational Approaches for Raga Identification

Music is the most fascinating and popular art forms in the society. In Indian context, ragas are the main pillars of different music types and genres. They have a strong academic foundation. Light music is most widely heard and appreciated form of music worldwide. Every light music composition has its roots somewhere in the core classical music and ragas. Hence the raga identification of an Indian classical raga is an academically attractive research problem in computational musicology which has attracted attention of various research scholars. A computational approach for automatic raga identification can enable raga-based Music Information Retrieval and popularization of Indian Classical Music. This paper presents a survey of computational approaches attempted till date. The approaches used are also discussed in detail.
