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).

Though limited by the necessity of the existence of individual "swaroopas" (unique identities) for the "janya" ragas, a list is never comprehensive or exhaustive.

The 72 "Melakarta" ragas are numbered according to the ancient Indian system for numerical notation — the "Katapayadi system".
