Title: "Improved Methodology of Raga Discrimination in north Indian Classical Music by the Method of Correlation of Frequency Distribution of Pitch Profiles"
Pitch profiles of total 76 songs of 4 ragas of north Indian classical music, sung by 19 musicians of varied expertise were considered for the present work. Correlation of the distributions of those profiles were calculated, both self and cross, to detect similarities and dissimilarities exhibited by inspecting the correlation values. The results show, in general, high values of correlation between songs of same raga but low values between songs of different ragas. The work is basically extension of our previous work  but with a modified method and with larger database. The result shows great improvement over the previous result.
