Kevalananda -sarasvati's Miimaa.saa-ko.sa vol. 52975-2979 will provide several potentially helpful references. The notion rathantara frequently associated with  b.rhat-saaman is noted on vol. 6 pp. 3289-3303 of the same.

In Bhagavad-gita 10.35, Krsna says, "Of sAmans, I am bRhat-sAman…"

Could someone kindly explain exactly what the bRhat-sAman is?
