Analysis of Lengths and Similarity of Melodies in Raga Bhimpalashree

In monophonic melody analysis, significance of a melody is measured by multiplying its length with the number of times it occurs. An analysis of melody lengths begins a new line of investigation (for a more comprehensive account, see Chakraborty et al. 2011–2012; this is possible in the first work on melody lengths). The strength of our results stems from the fact that a structure analysis discovers several interesting facts of the raga without restricting to any specific artist. The sequence of the raga notes, taken from a standard text, is given in Appendix of Chap. 4. A raga is a melodic structure with fixed notes and a set of rules characterizing a certain mood conveyed by performance. Two melodies, of equal length, are similar if the correlation coefficient of their shapes is significant. These concepts are detailed in the next section.
