I guess that there are some of us that need to think about survival, and others that just do the job. Maybe we are just lucky, maybe we have an approach to playing that offers more endurance. I know that my teaching involves REDUCING tension more than winding players up. I too get paid for what I do and paid rehearsals are no different than performances. As I get paid to play the ink and other professionals have no "requirement" to add octaves that are not notated, I really don't know what Local is talking about. Most of the gigs that I play are the rehearsal and concert on the same day - very often both are recorded. No room for cheating. I could imagine that a high school band director would have to say stuff like this. Before school concerts many a trumpeter has warmed themselves into a "wasted state".
