This arrangement of Music for the Royal fireworks is in the non-original key of F major (original is D major). There are two sections of four horns each, roughly representing the winds and string respectively. The transcription is faithful to the original, besides the key, and while difficult, playable by advanced horn ensembles. To make it easier on the chops, or to simply revert back to the original key, it is recommended reading the parts in D (or E flat if D is too hard).
