Melakarta is a collection of fundamental ragas (musical scales) in Carnatic music (South Indian classical music). Melakarta ragas are parent ragas (hence known as janaka ragas) from which other ragas may be generated. A melakarta raga is sometimes referred as mela, karta or sampurna as well.
Rules for Melakarta 
Ragas must contain the following characteristics to be considered Melakarta.
- They are sampurna ragas – they contain all seven swaras (notes) of the octave in both ascending and descending scale
- They are krama sampurna ragas – that is the sequence is strictly ascending and descending in the scales, without any jumps or zig-zag notes
- The upper shadjam is included in the raga scale (ragas like Punnagavarali and Chenchurutti are not melakarta as they end with nishadham)
- The ascending and descending scales must have the same notes
The mela system of ragas was first propounded by Raamamaatya in his work Svaramelakalanidhi c. 1550. He is considered the father of mela system of ragas. Later Venkatamukhi, a gifted musicologist in the 17th century expounded a new mela system known today as melakarta in his work Chaturdandi Prakaasikaa. He made some bold and controversial claims and defined somewhat arbitrarily 6 swaras from the known 12 semitones, at that time, to arrive at 72 melakarta ragas. The controversial parts relate to double counting of R2 (and similar swaras) and his exclusive selection of madyamas for which there is no specific reasoning (also known as asampurna melas as opposed to sampurna ragas). However, today the 72 melakarta ragas use a standardized pattern, unlike Venkatamakhi's pattern, and have gained a significant following. Govindhacharya is credited with the standardization of rules and known for giving different names for standard ragas that have a different structure but the same swaras as those proposed by Venkatamakhi. The scales in this page are those proposed by Govindhacharya.
Determining the Melakarta 
A hundred years after Venkatamakhin's time the Katapayadi sankhya rule came to be applied to the nomenclature of the melakarta ragas. The sankhya associates Sanskrit consonants with digits. The digits corresponding to the first two syllables of the name of a raga, when reversed, give the index of the raga. Thus the scale of a melakarta raga can be easily derived from its name.
For example, Harikambhoji raga starts with syllables Ha and ri, which have numbers 8 and 2 associated with them. Reversing them we get 28. Hence Harikambhoji is the 28th Melakarta raga. See Katapayadi sankhya for more details and examples.
Melakarta scale 
Each melakarta raga has a different scale. This scheme envisages the lower Sa (Keezh Shadja), upper Sa (Mael Shadja) and Pa (Panchama) as fixed swaras, with the Ma (Madhyama) having two variants and the remaining swaras Ri (Rishaba), Ga (Gandhaara), Dha (Dhaivatha) and Ni (Nishaadha) as having three variants each. This leads to 72 seven-note combinations (scales) referred to as the Melakarta ragas as follows.
There are twelve semitones of the octave S, R1, R2=G1, R3=G2, G3, M1, M2, P, D1, D2=N1, D3=N2, N3 (see swaras in Carnatic music for explanation of these notations). A melakarta raga must necessarily have S and P, one of the M's, one each of the R's and G's, and one each of the D's and N's. Also, R must necessarily precede G and D must precede N (krama sampoorna raga). This gives 2 × 6 × 6 = 72 ragas. Finding melakarta ragas is a mathematical process. By following a simple set of rules we can find the corresponding raga and the scale associated with it.
A raga which has a subset of swaras from a Melakarta raga is said to be a janya (means born or derived from) of that Melakarta raga. Every raga is the janya of a melakarta raga. Janya ragas whose notes are found in more than one melakarta raga are assigned (or associated) parent Melakarta based on subjective notions of similarity. This is obvious for ragas that have less than seven notes. For such ragas it can be associated with a Melakarta which has any of the different swaras in that position. For example, Hindolam has Rishaba and Panchama missing. Hence, it could be considered a janya of Todi (also known as Hanumatodi) which has shuddha rishaba or with Natabhairavi which has a chathusruthi rishaba. It is popularly associated with Natabhairavi.
The 72 melakarta ragas 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), as illustrated below. The name of each of the 12 chakras suggest their ordinal number as well.
- Indu stands for the moon, of which we have only one – hence it is the first chakra.
- Netra means eyes, of which we have two – hence it is the second.
- Agni is the third chakra as it denotes the three divyagnis (fire, lightning and Sun).
- Veda denoting four Vedas is the name of the fourth chakra.
- Bana comes fifth as it stands for the five banas of Manmatha.
- Rutu is the sixth chakra standing for the 6 seasons of Hindu calendar.
- Rishi, meaning sage, is the seventh chakra representing the seven sages.
- Vasu stands for the eight vasus of Hinduism.
- Brahma comes next of which there are 9.
- The 10 directions, including akash (sky) and patal (nether region), is represented by the tenth chakra, Disi.
- Eleventh chakra is Rudra of which there are eleven.
- Twelfth comes Aditya of which there are twelve.
These 12 chakras were also established by Venakatamakhi.
Table of Melakarta ragas 
The 72 melakarta ragas can be divided into two parts. viz.,. suddha Madhyama and prati Madhyama ragas. When a given suddha madhyama raga's M1 is replaced by M2, we get the corresponding prati madhyama raga. See Katapayadi sankhya for more information on how to derive the various swaras of a raga from its melakarta number.
See swaras in Carnatic music for explanation of the notations like R1, G2, N2, etc.

Alternate Melakarta scheme 
Muthuswami Dikshitar school followed a different set of scales as the 72 Melakarta ragas. These were taught by Venkatamakhin. Many of the scales were asampurna (not sampurna ragas) because Dikshitar chose to change the structure to mitigate ill-effects of usage of direct vivadi swaras in the scales.
