EDIT: Solved! It's most likely a Shehnai! Thank you Forza SoundFire!
I know this might seem really random on a pony forum, but I would love it if anyone could identify the wind instrument used throughout this song (I assume it might be the instrument that is shown at 1:37 in the video, right after the trumpet):

EDIT: Picture of what I could guess is the instrument making the awesome sound: http://i.imgur.com/VQkFRr9.png
At first I thought it was just a trumpet, but it has a very awesome, nasal sound to it. I've fallen in love with the sound of the instrument, but I can't go searching for samples without knowing what the instrument actually is.
Any help is most appreciated!
