I really want to make the most out of this coming summer - I'd like to build up my air and build up my face and work on my tuning. Here are a few of my goals. Just for reference, I'll be going into Grade 12 next year: 1) I want to convince my parents to shell out part of the money for a pro horn (Any convincing arguments, by the way? I'm really seriously considering going into music education.). I'm on a student Getzen I've been playing since Grade 7 and it's just not cutting it anymore. 2) I want to really beef up my flexibility and range especially. At present, I can semi-consistently nail some stuff just above high C (depending on the day, anywhere from D to G), but this inconsistency is really bugging me. Some additional flexibility would be nice. I think I have to really work on strengthening my air column, but does anyone have any suggested exercises that will generally help with flexibility and range? 3) I've been running into some endurance problems as of late, and I paid special attention to letting the face relax as much as possible and letting the air do the work in Grade 10. Any strategies to combat fatigue? 4) I want to become more fluent in all of my keys and also become a better improviser in jazz. Any general tips for this? 5) In short, how can I make the most out of this summer so that I improve as much as I can?
