This is a cute little novelty piece by Gautier, written first for piano. I arranged it for quartet, but dedicated one part as a solo - it can be either euphonium or tuba. This particular recording features Gary Buttery on his F tuba. The ensemble parts are probably grade 3-4, and the solo part is probably grade 4 on euphonium or 5 on tuba.
