Well yeah that's true, but this is a different version and its in a different key, but I would like to get this version which is why I asked if anyone knows where to get it, but thank you for your help!
Tyler, This is a Willson 3200RZ rotary valve F tuba. The mouthpiece is a custom, one of a kind, Doug Elliott component system. 128 rim, heavyweight N cup and an NE shank.
You shouldn't need sheet music. There's three chords, e.g., F Bflat F C7 (repeat over and over) and a simple melody which you can pick out. If you have trouble doing that, you're over-thinking it. Good luck!
