Tabla and Mrdangam are the main percussion instruments of North and South India respectively. Both traditions are highly virtuosic and are organized around timbre. "melodies" are created from timbres as opposed to pithces and organized in a highly structured way. The system is analaogus to language in that small units are combined hierarchically to form larger expressions
We have created the first systems that are able to 'listen' to tabla and mrdangam and understand the the rhythmic and timbral information, i.e. what stroke was played and when. We have begun using this information to create realtime interactive systems such as Tabla Gyan and Dangum.
