Brihat-Saama, then, among the Sama, Gayatri among the [Vedic] meters am I.
Among months, Margashirsha am I, among seasons the blossoming.

Source: Milind S. Pandit

I am Brihatsaama among the hymns. I am Gaayatri among the mantras, I am Maargsirsha (November-December) among the months, I am the spring among the seasons.

Source: The Bhagavad-Gita: The Sacred Song

Of hymns I am the Brhat-sama sung to the Lord Indra, and of poetry I am the Gayatri verse, sung daily by Brahmanas. Of months I am November and December, and of seasons I am flower-bearing spring.
