I'm taking an audition for the assistant principal bass position in a regional (per service) orchestra next month and on the audition list they are asking for a "concerto of your choice." I usually play the Koussevitzky for auditions, but have recently performed Per Questa Bella Mano for a recital and I think it sounds more impressive than the first few minutes of any bass concerto. Could I get away with playing that for a concerto of my choice even though it's not a concerto?
