The Sama-Veda (Sanskrit sāmaveda ) is the “Veda of chants” or “Knowledge of melodies”. The name of this Veda is from the Sanskrit word sāman which means a metrical hymn or song of praise. It consists of 1549 stanzas, taken entirely (except 78) from the Rig-Veda. Some of the Rig-Veda verses are repeated more than once. Including repetitions, there are a total of 1875 verses numbered in the Sama-Veda recension published by Griffith. Two major recensions remain today, the Kauthuma/Ranayaniya and the Jaiminiya.
Its purpose was liturgical and practical, to serve as a songbook for the “singer” priests who took part in the liturgy. A priest who sings hymns from the Sama-Veda during a ritual is called an udgātṛ, a word derived from the Sanskrit root ud-gai (“to sing” or “to chant”). A similar word in English might be “cantor”. The styles of chanting are important to the liturgical use of the verses. The hymns were to be sung according to certain fixed melodies; hence the name of the collection.
