Description :Carnatic music is highly phrase-oriented, with movements from note to note or oscillations (gamakams) of a note playing a greater part than the use of steady notes of a particular scale. For computer applications such as generating score or notation from live music or generating synthetic music from notation ragam identification. etc.,it is necessary to have a knowledge of the pitch values of the notes and the manner in which the pitch of the melody varies in a phrase or with in an oscillated note in a particular ragam. Gaurav Pandey et al had tried raga identification of Hindustani ragas using computer analysis of recorded melody (Ref. I). In this study they have presumed a certain minimum duration of constant pitch for a note,but as may be seen from the pitch graphs in this paper in Carnatic music the notes may be entirely held as oscillations without any perceptible steady pitch for even a short period. It there fore becomes necessary to charcterize a note on the basis of the entire movement rather than a single pitch.Characterization of gamakams using quantitative parameters is a difficult task especially in situations where the artist's imagination plays a very significant role and wide variations are possible within broad limits.

Carnatic music is highly phrase-oriented, with movements from note to note or oscillations (gamakams) of a note playing a greater part than the use of steady notes of a particular scale.
