Hello TM, This is my first post here since I've just found the site as of two days ago. I'm a returning trumpet player who hasn't played since middle school. You could almost say I'm a new player aside from the fact I played 3 years total and went to all-state back then. I and a bunch of my other friends quit when a new assistant band director joined the program and took over our side of the band. I'm now in my 2nd year of college and returning. Better late than never, right? I've grown a strong love for music and wanted to pick my trumpet up again. Since this May, I've been taking lessons as well as playing each day for an hour or two. I've slowly progressed from not knowing what note is what to being able to hit a steady A over above-the-staff G. I'm hoping to join a huge marching band program at a college I'm transferring to. After that, I eventually hope to possibly work up to jazz play 2 years from now. Fast forward to the point: During practice with my instructor Monday and on Tuesday night when I got home from work I squeaked and couldn't land a E/E sharp/F on the top of the staff. The only way I can describe the sound is my trumpet was trying to hit both above and below the note I aimed for, but could never hit that note so it sounded completely awful just erratically blasting the two notes out inconsistently. This was over taking breaks after that for 1-2 hours and trying again, and so on for about 4 sessions total Tuesday. At the same time, I could land everything up to the E and everything F sharp and above, including an A above the staff. Any ideas why? I've been practicing more consistently each day since the marching band auditions are coming up near immediately and I want to make sure the same thing doesn't happen again. Auditions are in two days so I'm hoping to get everything cleaned. Does anyone have any ideas why this would happen? In addition, if you have any advice on working up speed with playing 8th notes, some slurred, some not, that would be great as well. Think 8th notes in cut-time at moderato-allegro(120bpm) for an idea of what I mean.
