A "melakarta" raga is sometimes referred as "mela", "karta" or "sampurna" as well, though the latter term is inaccurate, as a "sampurna" raga need not be a "melakarta" (take the raga "Bhairavi," for example). Varṇam is a form of song in the Carnatic music repertoire consisting of short metric pieces which encapsulate the main features and requirements of a "raga".

Janya ragas are Carnatic music ragas derived from the fundamental set of 72 ragas called "Melakarta" ragas, by the permutation and combination of the various ascending and descending notes.  The process of deriving janya ragas from the parent "melakartas" is complex and leads to an open mathematical possibility of around thirty thousand ragas.  Though limited by the necessity of the existence of individual "swaroopas" (unique identities) for the "janya" ragas, a list is never comprehensive or exhaustive.  Thus the list below is open to additions or corrections.  Moreover, some musicians experiment and use new scales, leading to new "janya" ragas.  The 72 "Melakarta" ragas are numbered according to the ancient Indian system for numerical notation — the "Katapayadi system".
