In dreams

Howard Shore Movies-TV

"In Dreams" by Howard Shore is typically performed in the key of G minor. Composed by Howard Shore, the song is featured in the soundtrack of the film "The Lord of the Rings: The Fellowship of the Ring," released in 2001. One interesting fact is that "In Dreams" is sung by Edward Ross, but it is lip-synced by the character Galadriel, played by Cate Blanchett, in the film. The melody features haunting vocals accompanied by a symphonic arrangement, creating a sense of mystery and enchantment that reflects the magical and fantastical elements of the film.
