Abstract
In this work we propose a method to identify the raga of a Carnatic music signal. Raga is analogous to melody in Western music but is much richer and stronger in its representation. The main motive behind Raga identification is that it can be used as a good basis for music information retrieval of Carnatic music songs or Film songs based on Carnatic music. The input polyphonic music signal is analyzed and made to pass through a signal separation algorithm to separate the instrument and the vocal signal. After extracting the vocal signal we segment the vocal signal using our proposed segmentation algorithm. Using our proposed singer identification algorithm we determine the singer to know the fundamental frequency of the singer. The frequency components of the signal are then determined and we map these frequency components into the swara sequence and thereby determine the Raga of the particular song, which could be used to index the songs and further for retrieval based on the Raga.

INTRODUCTION
Music information retrieval is the need of the hour due to the availability of large amount of music on the Internet. Music information retrieval can be thought of as part of Multimedia information retrieval. A lot of work has been done in the other components of multimedia like text, video and the one that is yet to be fully developed is audio. Audio processing involves processing speech and music. In this paper we discuss music processing which could be used as the basis of music information retrieval using music characteristics. This paper is organized as follows: Section 2 discusses about the Characteristics of Carnatic music, Section 3 discusses on Existing work in Raga and melody identification, Section 4 discusses on the proposed System Architecture, Section 5 discusses on Results and Evaluation and Section 6 concludes the paper.
