Graha bhedam

Operation in Carnatic music

Graha Bhedam in Carnatic music is the process of shifting the Tonic note (śruti) to another note in the rāgam and arriving at a different rāgam. Its equivalent in Hindustani classical music is called a murchhana. Expressed in Western music theory terms, this is the process of arriving at a different scale by shifting to another mode in the key.
