Time domain analysis of Indian classical raga rendition

The area of music information retrieval is very wide in general and Indian classical music in particular. Raga is the most significant aspect of Indian classical music which is further divided into Hindustani and Carnatic forms. One of the distinguishing features of the Hindustani classical music is the time of rendition of a raga. With contrasting opinions offered by musicians on the issue, with some being strict and others labeling it as purely imaginary, it is of interest to investigate whether there are any scientific aspects as to why the Hindustani ragas have been grouped for a particular time of rendition. This paper attempts to investigate audio features of different ragas which are rendered in morning, afternoon, evening and night.
