Hello. I'm sure there are a ton of threads like this, and for that I apologize. My issue is that I am so frustrated at my lack of growth in terms of my range. I have had the same useable range for a year now. I am a junior in high school, I take private lessons, I practice everyday and try to make sure I'm doing everything right, to the best of my knowledge. I just feel as if my work is vain because I can't perform anything above an A above staff. It wouldn't be as bad, but I need a C above staff for this marching season. I've worked and worked trying to expand my range, doing everything my teacher said as well as trying various online suggestions. I was hoping someone could tell me why I haven't seen any growth as well as help me expand my range. Thank you.
