You don't do it until you can't miss. You do it until you can do it on your worst day, when your significant other has just left with the pool person after a shouting match in the car that contained ALL of your good horns and every mouthpiece you owned, leaving you to do it with a Dylan fiberglass BBb Sousaphone.
And the ushers don't put notes about what you're up against in the programs, nor does the conductor make any announcements to the audience about it, either. If they do say anything, it'll be an amusing "a funny thing happened to me on the way to the concert" story, or about how Barber's School For Scandal overture was actually written about the obedience training class for his pet terrier, Scandal.
All that said, I like the way it sounds done on a 6/4 F. It feels more secure done on a euphonium. I don't think it matters what the picture was, what Modest meant, or even what Ravel had in mind. It's what the conductor wants (no matter how wrong I think they might be), for what I consider to be a very lyrical solo, with a driving accompanyment. And if I can't do that, I picked the wrong business.
