I've been searching and searching but Trumpet sheet music is hard to come by, and I've been wanting to play and hear Yuna's Ballad on my trumpet. Hope to hear back from someone. *Any Trumpet sheet music you can find will work for me!!*
The main song I'd like though would be
Yuna's Ballad
for the Trumpet *of course*

Apologies if this isn't what you're looking for, but if you just buy the X-2 sheet music book for piano, and follow the melody with your trumpet, you should get the same end result as a specific trumpet transcription.
