021 :Music Info - Carnatic : Raaga?

It's like trying to dry the ocean, if some one attempts to create a repository or reference for Music. But the process of collaborative learning is more effective, hence i'm planning..this series. Lets explore the ocean of Music together
What is a Raaga?
A Raaga is a combination of musical notes aka Swaraa(Sa Re Ga Ma Pa Dha Nee). Raaga primarily denotes melody. Ideally there must be at least 5 notes or a maximum of 7 notes (swaras) in a Raaga

"tonal framework for composition and improvisation" -Joep Bor of the Rotterdam Conservatory of Music

Every Raga would have an “Aarohanam” - ascending notes & an “Avrohanam” - descending notes.There are many ragas recognised and played in Carnatic Music and each ragas has its time and season that defines it.

Melakarta or Janya Raagas:
Melakarta is a collection of fundamental Raagas Melakarta ragas are parent ragas (hence known as janaka ragas) from which other ragas may be generated. There are 72 Melakartha Raagas. They are split into 12 groups called chakras, each containing 6 ragas. The ragas within the chakra differ only in the dhaivatham and nishadham notes (D and N), You can find the list of all the 72 Raagas and the chakra's they belong to in the following link http://carnatica.net/sangeet/melachart.htm
