legend of Zelda website- soundtrack
you can find labeled and unlabeled Zelda sheet music for piano at herbalcell.com if that does not work try this adress-> http://www.herbalcell.com/free-sheet-music/zelda-link-to-the-past
in a music shop
You buy it in a game store or a music game store or other stores but stores that got games!
I find this website useful. It's written for piano, but I use it for my flute so it might work with trumpet. Just scroll down until you see the hyrule field music. http://herbalcell.com/blog/free-sheet-music/legend-of-zelda-twilight-princess Hope this helped :D

I get most of my sheet music from http://ichigos.com/ But i play flute so I'm not sure if they have a lot of cello sheet music if your interested in Zelda sheet music there is a whole bunch on that website :3
Google Legend Of Zelda Violin Sheet Music, or make it more specific, and put the song you want instead of Legend of Zelda, For Example "Sarias Song Sheet Music"Try here http://ichigos.com/ They have a lot of Zelda music, I didn't check for violin though. It will tell you under the name of the song what it was transcribed for.
