TWENTY TWO SRUTHI SYSTEM

In Indian Carnatic Music, there are seven notes or Swaras, which are known as Sapthaswaras.
They are:
Shadjam, Rishabham, Gandharam, Madhyamam, Panchamam, Daivatham and Nishadham.
Shadjam and Panchamam are constant notes and the other five swaras have two different positions.
With the above, we derive twelve different positions. These are known as twelve Swarasthanas.
They are:
Shadjam, Suddha Rishabham, Chathusruthi Rishabham, Sadharana Gandharam, Andhara Gandharam, Suddha Madhyamam, Prithi Madhyamam, Panchamam, Suddha Daivatham, Chathusruthi Daivatham, Kaisiki Nishadham and Kakali Nishadham.
In the above twelve swarasthanas, we know that Shadjam and Panchamam are constant notes and they never change. Rest of the notes have different positions, which are known as Sruthis. These positions are very delicate to understand, since the distance between two notes is very small. So, in total there are twenty two different positions in Carnatic Music System and it is known as Twenty two sruthi system.

1. Shadjam
2. Eka sruthi Rishabham
