horncall of buckland

[Puddleglum]

And straightaway all the horns in the host were lifted up in music, and the blowing of the horns of Rohan in that hour was like a storm upon the plain and thunder in the mountains.
Ride now, Ride now! Ride to Gondor!

Possibly, tho it's always seemed to me that these words were also cried out by Theoden (even tho that isn't explicitly stated). Ie, that the sequence was:

1. Theoden makes his "arise now" call, ending with a first "Ride now, Ride now, Ride to Gondor"
2. Theoden blows such a blast that his horn bursts.
3. The Rohirrim respond with a blowing of horns "like a storm upon the plain."
4. Energy builds until Theoden cries again "Ride now, Ride now! Ride to Gondor!", Yells to & spurs Snowmane, and leads the Glorious Charge; Adrenaline pumping; "Borne up as a god of old, even as Orome the great in the battle of the Valar when the world was young."
