For Pennsylvania's All-State Wind Ensemble music this year, we're playing the Barber Commando March, which is awesome . . . but pretty difficult. Does anyone know of a really fantastic way to trill high Bb to high C? It's a sustained trill, and I've been fingering it using the F#3 with the thumb Bb key . . . overblowing it . . . and trilling my thumb. This has been working out ok, but does anyone know of anything different?
