The udgîtha, of which a poet said, I choose the deep sounding note of the Sâman as good for cattle, belongs to Agni; the indefinite note belongs to Pragâpati, the definite note to Soma, the soft and smooth note to Vâyu, the smooth and strong note to Indra, the heron-like note to Brihaspati, the dull note to Varuna. Let a man cultivate all of these, avoiding, however, that of Varuna.

In plain words: The main part of the chant, the udgītha, can be sung in different tones, and each tone belongs to a different god. A deep tone belongs to Agni, god of fire; others belong to Prajāpati the creator, Soma, Vāyu the wind, Indra king of gods, and Brihaspati the gods' teacher. The dull tone belongs to Varuna, and a singer should use all the tones except that one.
