Similarity Estimation for Classical Indian Music

Music is a complicated form of communication, where creators and cultures communicate and expose their individualities. Thanks to music digitalization, recommendation systems and other online services have become indispensable in the field of Music Information Retrieval (MIR). Classification of music is essential for music recommendation systems. In this paper, we propose an approach for finding similarity between music. Our approach is based on mid-level attributes like pitch, midi value, interval, contour, and duration, and applying text-based classification techniques. Performance evaluation has been done using the accuracy score of scikit-learn. As a preliminary study, our system first predicted jazz, metal, and ragtime for western music. The genre prediction system has been tested on 476 music files with a maximum accuracy of 95.8% across different n-grams. Then, we have analyzed and classified the Indian classical Carnatic music based on their raga. Our system has predicted Sankarabharam, Mohanam, and Sindhubhairavi ragas. The raga prediction system was tested on 68 music files with a maximum accuracy of 90.14% across different n-grams.
