Yes i am in my schools band. I have a director and i know how to set my embouchure pretty good. I use an electronic tuner. I also use a 3 reed(java). Lately after having some lessons by a professional*, after warming up for a significant amount of time it would become in tune. but barely. It just really takes time for it to become better. My tone production isnt one of my biggest concerns because it is improving. I also noticed trying to play loud is pretty hard. Its like my instrument is stopping me. Is it the mouthpiece, are different mouthpieces made for different uses?
-Sorry for the noobness but im only in 8th grade.
