FYI, I am playing the following:
Plog - 10 Concert Duets for Trumpet... just I and IV.
Clarke - Carnival of Venice (not the Arban)
Antheil - Sonata for Trumpet
Arutunian - Concerto for Trumpet and Piano
Water bottle prepared... be hydrated beforehand, too... play lightly 3-4 days prior.... know my mute changes.... position the stand properly... communicate with the pianist... know the pieces...
Any other advice is appreciated. I hope for maximum efficiency to not only make it through it, but to relish the joy of playing music the whole time.
