I was just thinking about all the jobs I have had. I have never once been asked to produce a copy of my degree certificates. I am a decent trumpet player. I can play most things. I wonder if I managed to get an audition for fourth trumpet in an obscure orchestra (e.g. Outer Mongolian Sinfonietta) would I be able to steal the job based solely on my playing ability, with no qualifications? Just an interesting thought..... Third or fourth trumpet is not difficult and I doubt anyone could tell my playing from any of the lower trumpet players in the more obscure orchestras.
