So I've had on and off private lessons for my trumpet career and around the time I was in 6th grade before I had lessons I managed playing with 99% of my top lip out of the trumpet ( I can't even make a sound like this anymore at all or buzz) and transitioning in to about my freshman year in high school probably with marching band my embouchure slid a little bit to the left after I fixed my top lip from being out of the trumpet. Now I mostly centered the embouchure but I just realized recently that my left side is like 3x stronger than the right, if I play any note in front of the mirror my left side looks far more flexed than the right and I also realized that VERY soon in to practicing my right side starts to leak air when I play moderately loud or moderately high ( F on the top of the staff and up). I've been listening intently and I realized also that when my air starts to leak from the right side my tone suffers and becomes brighter/ less pure. Is there anything I can due to help the right side get up to par with the left? This also probably hurts my range from improving.
