Classification of Indian Music using intrinsic mode functions based features

Abstract

Indian music is very rich in emotional content and technicalities. It is also contrasting having multiple genres which may be broadly classified as Classical (Hindustani or Carnatic) music, Semi-classical music (including Ghazals) and Light (including folk) music. The so called “rasa” or emotional content in Indian music is of much significance, e.g. selection of the right kind of music for therapeutic intervention by the music therapist who might be an expert in western art music (WAM) but could be new to Indian music. This paper presents a novel classification technique based on empirical mode decomposition (EMD). In this work, two genres of Indian music, Classical and Semi-Classical, are considered. There is a significant increase in classification accuracy as compared to previous works involving generic audio features.
