Transpose horn to Melodica? HELP!

Hey all,

I'm new to the melodica. I would love to play the horn section from the song Hell by Squirrel Nut Zippers. I found the horn tabs here: http://www.horntabs.net/h/tabs/squirrel-nut-zippers/hell-with-solo

I have no idea what to do with this! If anyone could help out that would be great! Thanks.

Sean
