Does anyone know a good way to make your trumpet sound like a horse. I have heard it in a couple different Christmas carols and it sounded so cool. Any help would be appreciated.

valves half way down or 1st valve down and 3rd valve half way down. start the note and get higher and then fall lower while shaking the horn.

THANKS!!!! That is bad ass. I just tried it. I haven`t exactly mastered it yet but I got it a lot closer than before.

Does anyone have any other ideas?

nah, thats really the best way to do it. theres a horse part at the end of the original sleigh ride.. and if its done right, it sounds really cool.

Don`t just shake the horn, kinda virbrate the valves back and forth.
