The Sama Veda is the Yoga of Song. It consists of various hymns of the Rig Veda put to a different and more musical chant. Hence the text of the Sama Veda is a reduced version of the Rig Veda.

Its secret is in its musical annotation and rendering. The Sama Veda represents the ecstasy of spiritual knowledge and the power of devotion. The Rig Veda is the word, the Sama Veda is the song or the meaning. The Rig Veda is the knowledge, the Sama Veda its realization. Hence the two always go together like husband and wife. The Rig Veda is the wife and the Sama is the husband.
