Major Shire Variants:
The White Tree
Into The West
Merry and Pippin
This variation on the Shire theme is used to signify Frodo and Sam setting off on their own, suggesting as it does that they carry a bit of the Shire with them as they head into strange and threatening lands. Significantly, it is heard at the end of each of the first two movies, as the next phase of their journey begins. The mood is hopeful rather than trepidatious; the music swells upward, higher and higher.
||Frodo sets off in the boat by himself.
||Sam delivers his awful "shine out all the brighter" speech. (I'm sorry, I think this speech is a major mistake. Not only is it treacly and trite, it's out of character for the earthy and unpretentious Sam.)
