Carnatic Music Theory Notes.

[Pracalpa]

Sangeetham is an Indian term for Music. A group of musical sounds, which are
called swaras that give melody and pleasant feelings to the ears, is called
Sangeetham. Ancient writers hold the view that vocal music, instrumental
music and dance together constituted sangeetham. Later, dance was
separated from the first two.

Shruthi is an audible sound which can be heard distinctly. It is a musical sound
which a well trained human ear is capable of distinguishing. It is the Key note
or Adhara Shadjam, based on which all other Swaras are derived.

Swara is a musical note which is pleasing to the ears. There are seven basic
swaras, known as Saptha Swaras. They are -

1. Shadjam (shortly - Sa)
2. Rishabham (Ri)
3. Ghandaram (Ga)
4. Madhyamam (Ma)
5. Panchamam (Pa)
6. Dhaivatham (Dha)
7. Nishadham (Ni)

Dwadasa Swarasthanas

Out of the seven swaras, Shadjam (Sa) and Panchamam (Pa) are constant. They
are called Achala Swaras. The remaining five swaras admit varieties and they
are called Chala Swaras. In combination, both Achala and Chala swaras yield 12
different musical notes and they are called Dwadhasa Swarasthanas.
