Speaking as a professional with 30 years in the industry of professional entertainment and working with tons of A-list talents and shows garnering millions of dollars in cleared income PER SHOW:
1: Based on how long it takes to come up with a routine, it’s kind of late in the game to be asking these sort of questions. At this point, you need a 1 minute music piece for your prelims and a 2 minute for your final. Whatever you do, make sure what you’re doing fills up the time. Bind back between tricks and use that as your transition.
2: Many players, the music is merely a bed that does nothing but consume audible space during a routine. For some, especially the more seasoned players, they make the routine go with the music. For you, first time, the music should just be a bed to take up space.
3: Stage fright. It’s hard to deal with. What works for some doesn’t work for others. I got over that ages ago, but it’s a necessity. I’m also NOT a featured player. I’m tech and I hit the stage when something needs to be taken care of. I’m usually Front of House mixing, so ideally I should NEVER touch the stage anymore! Deep breaths. Breath in, hold , release. Repeat. Find something to distract yourself. You have to go on the stage, accept this. Also realize the judges MUST judge for points, they are supposed to be critical. When they aren’t judging, they are your “friend” for lack of a better term. Do realize you’re performing in front of your peers and for the most part, they are on your side and they want you to do amazing. Still, being the focus of attention can be nerve wracking. If need be, I’ll talk you onto that state. I realize I’ll have to use the kid gloves treatment. When an A-Lister pulls that stuff, we just say “Look, you’re out of pocket $65K for the night regardless. The difference is, do you make 3X or 4X that tonight or do you just dig into your bank account to pay everyone else involved who is doing their job?”
Focus, ignore what you don’t need to worry about. You, the yoyo, the music. After that, nothing else matters.
Enjoy BAC. I’m doing sound. I don’t compete. I don’t ever compete. For me it’s not about competition, it’s about the job and the environment. Enjoy yourself!
