Raag Recognition - Raag Vidya

To our knowledge, we have created the first automatic raag recognition system which we call Raag Vidya. Our work is based on creating a theoretical framework that allows us to translate raag into a representation that reveals underlying structure, despite tremendous variety and complexity in the performance of raag and the sometimes subtle distinctions between raags.

Just as key recognition is essential for understanding Western tonal music (including pop, rock, jazz, etc) -- because it is fundamental to understanding the melodic and harmonic content of a piece -- raag understanding is essential for systems that interact with Indian music. Further our attempts to automatically recognize raag have provided theoretical insights into the nature of raag.
