But the lure of the One Ring is just so strong, and he wants SO badly to be able to save his people, that he feels compelled to take it from Frodo. When, after Frodo puts on the Ring then disappears, Boromir realizes what he has done, he feels like a fool for falling under the spell of the Ring, and then feels responsible for Frodo running off. He is haunted by that to the end and the knowledge that Merry and Pippin have been taken by the Orcs. But he dies knowing that Aragorn feels the weight of the people of Gondor as well, so he can turn that duty over to him.
Just a few thoughts that came from listening to the music. I haven't begun reading TTT again. I'll have to pick it up tomorrow.
I did the same thing, only I've now listened to it so many times that I've had to put it away so I won't get tired of it. I find it actually very evocative of the English countryside. Don't know if Shore meant it that way, but I suppose he must have, since it was such an important theme of Tolkien's.
