How good are you in identifying swarasthanas when you hear a musical sequence? Try this challenge:
Importance of this exercise
There are six valid combinations of Ri and Ga in Carnatic music (and very similarly there are six combinations of Dha and Ni). Cycles of Ri-Ga combinations and Dha-Ni combinations are the basis of the 72 Melakartha scheme, which is one of the backbones of our raga system.
So, it is critical that every student masters these combinations.
If you are fuzzy about Carnatic swarasthana numbering, read this post before checking the answer.
The sequence you heard is Sa Ri3 Ga3. That is, Shadjam - Shatshruti Rishabam - Anthara Ghandharam.
This combination popularly occurs in Nata Ragam.
