You know those metal detectors at airport security? That checkpoint where potentially dangerous items must be detected and then disallowed before you can proceed? Occasionally you may even be one of the fortunate few to stand there in that silly door frame while you are suddenly air-blasted by that machine that checks you for explosives! It matters not that you feel violated and humiliated as all can see that hole in your sock to boot! You must be absolutely up to snuff with no bad stuff. Security staff's mission is to search out and eliminate any items hazardous to your safety and to those around you.
Having survived that ordeal and after still further review of your credentials, you are then allowed to reclaim your shoes, belt, laptop, phone, spare change, and mouthpiece. You are finally pronounced good enough to go. You may now approach the moving sidewalk. (Watch your step as you approach the moving sidewalk.) By now you are fatigued and irritated, and you're still not even on the plane. Is this not very similar to a day at the auditions?
Getting yourself to the audition is almost as bad as playing it. In auditions only the best survive the grueling process, and you can be fairly sure they have no suitcases full of bad notes. The scanning process is thorough. Mettle is detected, but here it is desirable. You have passed scrutiny and have been found sound.
Thought for this snowy non-day: prepare to be completely evaluated and sifted. The committee wants to find a clean, strong candidate with no hidden or undesirable baggage. Our task as students is to anticipate this testing and to begin to eliminate all items that won't fly.
Incidentally, you've got more time to think about it. Your flight has just been delayed!
