Purvarchika and Uttararchika — the Two Books

The Sama Veda is laid out in two books — the Purvarchika (the “former collection”) and the Uttararchika (the “later collection”) — and the simplest way to grasp the difference is this: one is for learning, the other is for performing.

The Purvarchika contains about 585 verses, and it is arranged by deity. The opening section is the Agneya Parva, all the hymns addressed to Agni. The next is the Aindra Parva, the great body of hymns to Indra. Then the Pavamana Parva, the hymns to the purified soma. Then a small Aranya section, the forest chants. The principle of arrangement is doctrinal — group together what is sung to the same god — and the purpose is pedagogical. A student of the Sama Veda would learn the verses of the Purvarchika first, by deity, as a way of mastering the basic chants.

The Uttararchika is much larger — about 1,225 verses — and it is arranged not by deity but by the order in which the verses are sung during the actual sacrifice. If a particular soma rite calls for a certain chant at a certain moment, the Uttararchika lists the verses in that order, ready to be sung. It is, in effect, the working script — the order-of-service for the Udgatri priest performing the rite.

This two-book structure is the Sama Veda’s way of solving a teaching problem that any working musician knows. To learn a piece you organise the material one way — by key, by scale, by exercise. To perform it you organise it another — by what plays first, what plays second, what plays last. The Vedic tradition did the same thing with the chant. The Purvarchika trains; the Uttararchika performs.

There is also an important asymmetry between the two books. The Purvarchika is the verses — the words a singer learns first. The music for each of those verses lives separately, in the gana collections (we will come to those — there are four of them). So when a student learns the Purvarchika, he learns the words by deity, and then learns the melodies from the gana books. Only once both are in him does the Uttararchika make sense, because the Uttararchika presupposes that the singer already knows both the words and the tunes — it just tells him in what order to sing what he already knows.

This is why a reader picking up a printed Sama Veda today often feels that it does not quite hang together. It does not. It is one component of a larger system — the verse-book of a singing tradition whose melodies and ritual sequences live in other texts entirely. To understand the Sama Veda properly you have to hold all four pieces together: the Purvarchika for verses by deity, the Uttararchika for verses in ritual order, the gana collections for the melodies, and the actual living tradition where one priest is showing another how it goes. Modern printed editions have begun to combine these in ways the ancient transmission never did. The two-book structure on the page is the surviving fossil of a much richer oral system.
