For part of my high school senior project, I decided to transcribe part of a track from the score of The Chronicles of Narnia: The Lion, the Witch & the Wardrobe. The piece will be performed by a select group of students at our instrumental music spring concert in May.
The piano part was taken from the piano and harp parts of arrangements of this piece found on MuseScore.com. The wind, string, and vocal parts were transcribed by ear.

I post MuseScore audio of my arrangements on here to share with friends as well as some rehearsal and performance recordings idk
