Hi, I'm in my school's jazz band as a percussionist, and I also play guitar (Just not in Jazz Band). We are playing "Hot Chocolate" from the Polar Express movie, and I'm doing guitar on this song because we need a guitarist. I have the music, and it's almost all chords, but they're all really weird (Think F13, Bb13, C7/E). I also have a sheet of all the chord fingerings with the roots circled, but above all the fingerings, it doesn't have the chord name, just the add-ons (I don't know what they're called) like "Maj7", and "7(#11)". I have no idea how to match these to the chords in the song. HELP!
