Requirements and needs very per band program. It is never about volume but about different levels of being able to read music, tone quality, bands needs, technique, body strength (not everyone can play 20K's), your dedication level to your instrument.
Hey gent i've got a question, I've been playing sousa for almost a year. I'm ahead of all the other players in my school who have been playing 2-4 years. Is there a certain requirement in regards to sound and how loud you can play? or is it mainly about being able to actually read and play the music?
Oh, we'll them wouldn't be a problem for me because my high school uses 4 valve jupiters witch is 40 pounds, there good but i bet it's so much easier to blow throw a 3 valve to bad I've never played one though
