About 'Concerning Hobbits'From this Wikipedia article:
"Concerning Hobbits is an acclaimed piece by composer Howard Shore for The Lord of the Rings: The Fellowship of the Ring soundtrack. It is a concert suite of the music of the Hobbits, arranged from the music heard in the film during the early Shire scenes, and features the various themes and leitmotifs composed for the Shire and Hobbits and is intended to evoke feelings of peace."
"It is also the title of one of the sections of the prologue to The Lord of the Rings by J.R.R. Tolkien. Excerpts of the piece can be heard during an extended scene in the 2012 film The Hobbit: An Unexpected Journey, where it was tracked intentionally. The piece has become synonymous with the Shire and Hobbiton themes."
The piece also incorporates melodic elements from Enya's "May It Be," the song that plays during the closing credits of The Fellowship of the Ring. I don't know which was created first, so perhaps I should say Enya's song incorporates portions of "Concerning Hobbits."
