What is Swara ?
Indian music, as with all systems of music, has seven notes or swaras. Swara is defined as "that which is able to please on its own accord". Organisation of swaras in various patterns/orders creates Ragas. Time measure to Indian music is controlled by Tala.
The seven swaras in Indian music are:
Shadjamam
Rishabham
Gandharam
Madhyamam
Panchamam
Dhivatham
Nishadham
These are often represented as Sa, Re, Ga, Ma, Pa, Da and Ne, by their first syllable.
Of these seven swaras, Sa and Pa don't admit any variations and hence they are called achala (fixed) or avikratha (changeless) swaras.
The other five swaras - Re, Ga, Ma, Da and Ne allows two varieties each and terms Komal and Tivra are used to distinguish these two, with Komala swaram lower in note than the Tivra swaram.
Thus we have:
Shadjamam - An achala swara, does not admit any variations
Rishabam
Sudha (Komal) Rishabam
Chathusruthi (Tivra) Rishabam
Gandharam
Sadharana (Komal) Gandharam
Antara (Tivra) Gandharam
Madhyamam
Sudha (Komal) Madhyamam
Prati (Tivra) Madhyamam
Panchamam - An achala swara, does not admit any variations
Dhivatham
Sudha (Komal) Dhivatham
Chatussruthi (Tivra) dhivatham
Nishadham
Kaisiki (Komal) Nishadham
Kakali (Tivra) Nishadham.
Thus, in Carnatic Music we get 12 distinctive swaras or notes .
In addition, four of the swaras, Ri, Ga, Da and Ne extend to another variety overlapping with the next swarasthanam. This give rise to four more swaras. Note however that the note (swara sthana) is shared between two swaras. Thus totaling to 16 swaras in all.
It may be noted from the above, the sudha swaras, also known as prakrithi swaras have the prefix Sudha and is usually the lowest pitched note for that swara. The vikratha swaras have prefixes like chatussruthi, shatshuruthi, sadharana, antara. In Hindustani music, Sudha swara usually refer to Sankarabharana scale (Bilval).
