Brett, somehow I missed that link in the description the first time! Thanks for sharing. I feel like you would be interested in a piece I wrote about 6 months ago. Search "The Percussive Tuba". I really enjoyed your piece!
Shazamio, good work! However, could you please explain your reasoning for transposing this music for differently pitched tubas? In the tuba world, all music is written in concert pitch, not transposed for C, Eb, and F.
