Indian music tradition in the North as well as in the South, remembers and cherishes its origin in the Samaveda - the musical version of the Rigveda, says V.Raghavan.
The Samaveda comprises two major parts. The first part include four melody collections (gāna, गान) and the second part three verse "books" (ārcika, आर्चिक). A melody in the song books corresponds to a verse in the arcika books. The Gana collection is subdivided into Gramageya and Aranyageya, while the Arcika portion is subdivided into Purvarcika and Uttararcika portions. The Purvarcika portion of the text has 585 single stanza verses and is organized in order of deities, while Uttararcika text is ordered by rituals. The Gramageya melodies are those for public recitations, while Aranyageya melodies are for personal meditative use such as in the solitude of a forest. Typically, the Purvarcika collection were sung to melodies described in the Gramageya-Gānas index, and the rules of how the verses mapped to verses is described in the Sanskrit texts such as the Puspasutra.
