This week for my marching band is band camp week and we play about 4 hours everyday and the last of camp is friday, then the following sunday I have an audition for the Indianapolis Youth Wind Ensemble. My teacher tells me I would be competing for probably first or second chair in there and am worried that I would be tired after the long week of band camp. My teacher tells me it's a bad idea to admit 'defeat' or tiredness and it's a perfect opportunity to learn to use my air efficiently and do the audition. In the past I could play fine the day after long weeks like this but 2 days after I was completely shot. How do I increase my air efficiency on a lead marching band spot? Because especially this year it is a loud and high show. I realize I can't perfect it on my own in a week, I get to see my teacher once a week, but what should I do? My teacher tells me to relax, take a deep breath from my lower stomach area and release air, not force it. Maybe I am just not a good visualizer and am doing it wrong, but what do you guys suggest?
