I played the Barnes for my Junior Recital. I got the piece about a year and a half before I performed it because I was looking for a piece that had multiphonics in it. It took me the entire year and a half to work it up. I learned it one movement at a time (2nd, 1st, 3rd). The second movement is certainly the easiest. The more emotional you can get with it, the better. The first movement is pretty challenging. Make sure to get the playfulness to come through in this one. The final movement is VERY challenging if you decide to take it at tempo. Pay very close attention to James Barnes's marking as they provide excellent insite into how to perform the final movement, particurally the cadenza. I spent more time on that final movement than I did on both of the other movements combined. You more or less have to get it down to simple muscle memory. At least, that's what I had to do. As far as what tuba you play it on, it certainly would lay very well for a CC, however, I did it on a BBb just fine.

Best of luck on playing it. I found it a very rewarding piece to perform, as I am sure you will, too.
