Question: Who composed a form of song in the Carnatic music repertoire in all the '72 Melakarta Ragas?
Sentence (from "Melakarta"): 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).
Relevant evidence: No
