If you've seen my other post (http://www.trumpetmaster.com/vb/f131/what-happening-me-help-68736.html), you know about my frequent range drops usually due to too much playing in the upper register (usually during practice, not because of a long performance). I've calmed down since my last post, and for the past several days I've been doing very low impact practicing, focusing a LOT on clarke studies at a very quiet volume, lip bends, pedals and playing melodies of slow songs at pianissimo, which really makes my chops burn (in a good way), without overdoing it. I haven't touched the upper register since my last range drop. So now, my question is not just about rebuilding my upper register, but getting it to STAY there without losing it again. I've been good about rebuilding my range after I lose it with high impact exercises like lip trills in the upper register and ascending arpeggios. But I always manage to play too much too high and lose a good chunk of my range. One idea that I had, that I've heard a lot from teachers, is to alternate days of high and low intensity. In other words, every other day I would go all out and do all my intense range exercises, and on the off days do what I've been doing the past week (strong pedals, low register, and very soft mid-register). In theory this seems like a very good idea because not only would I be resting from all the upper register the previous day, but also building strength in a different way, by playing softly. Any opinions/additional recommendations on this? Also, will there be a point eventually, if I manage to go a long way without injuring myself, that I won't have to worry about this as much anymore? I really want to build range as fast as possible WITHOUT causing injury.
