The Upanishads - Mandhata Global

lord (pati). Therefore it is called Brahmanaspati.

Prana is Saman, too. Speech is, verily, sa and this
(prana) is ama. Saman (the chant of the Sama-Veda) is
known by that name because it is sa (speech) and ama
(prana). Or because it (prana) is equal (sama) to a white
ant, equal to a mosquito, equal to an elephant, equal to
these three worlds, nay, equal to this universe; therefore
it (prana) is indeed the Sama-Veda. He who knows this
vital breath to be such attains union with it or lives in
the same world with it.
23
And it is also the Udgitha. The vital breath is verily ut,
for by the vital breath all this universe is upheld
(uttabdha); and speech is githa (song). And because it is
ut and githa, therefore it is Udgitha.

Regarding this there is also the following anecdote:
Brahmadatta, the great-grandson of Chikitana, while
drinking king [soma], said: "Let this soma strike off my
head if I say that the ayasya angirasa chanted the
Udgitha through any other means than this vital breath
and speech." Surely he chanted through speech and the
vital breath.
