Graha bhedam

Graha Bhedam in Carnatic music is the process (or result of the process) of shifting the Tonic note (śruti) to another note in the rāgam and arriving at a different rāgam.

Graha literally means position and Bhedam means change. Since the position of the śruti is changed (pitch of the drone), it is also sometimes called Swara Bhedam or Śruti Bhedam though Śruti Bhedam and Graha Bhedam have some technical differences.[1]

Definition

Modal shift of the Tonic note to higher notes of a rāgam, while retaining the note's positions (swara sthānas – sthāna means position/ pitch), results in different rāgams. This is called Graha Bhedam.

Practical demo

A simple practical demonstration of Graha Bhedam can be taken up by playing the structure of a rāgam with the drone set to Sa (Shadjamam). Then if we keep playing the same keys/ notes, while shifting the drone to another note in the rāgam, to form the new śruti/ tonic note, the result is a different rāgam.

Example Illustration

When Graha bhedam is applied on Shankarabharanam's notes, it yields 5 other major Melakarta rāgams, namely, Kalyani, Hanumatodi, Natabhairavi, Kharaharapriya and Harikambhoji.

Notes on above table

Melakarta Rāgams

Graha Bhedam can be applied on most Melakarta rāgams to yield other Melakarta rāgams (16 of the 72 do not yield any valid Melakarta scale). When applying such modal shift of tonic note, some results are not valid Melakarta rāgams (rules of the definition of Melakarta are violated). Example scenarios are missing Panchamam (Pa) or two of particular note (Rishabham (Ri), Gandharam (Ga), Madhyamam (Ma), Dhaivatam (Da) or Nishadam (Ni)).

Janya rāgams

Graha bhedam can be applied to some of the janya rāgams to yield other janya rāgams. Unlike Melakarta rāgams, where strict rules are adhered to, in terms of which swaras can be chosen in a rāgam, janya rāgams do not have such rules. Hence, such modal shift of tonic note is valid on all swaras, but may not have been chosen as a rāgam, experimented, elaborated and composed. Hence they lead to theoretical rāgams, which have not yet been discovered (all combinations of notes exist, but no one has composed using a particular combination or experimented/ exposed to the world at large).

Mohanam

Mohanam rāgam and its graha bhedam derivatives are one of the key scales in use all over the world, especially East and South Asia. The other four derivatives are Hindolam, Shuddha Saveri, Udayaravichandrika (also known as Shuddha Dhanyasi) and Madhyamavathi.
