Backstory: My main problem with trumpet has always been the inability to play high and using too much pressure. I play with a lot of top lip and barely any bottom lip, I have heard 1/2 and 1/2 is correct and 1/3 top 2/3 bottom is alright, but I'm neither its probably 1/4 bottom, 3/4 top.
Today, while I was messing around I curled my bottom lip in, thus making my embouchure close to half and half. When I did this I used absolutely no pressure and could wail high notes left and right. Sounds great, right? Well, not so much, I couldn't play anything below a concert Bb on the staff without moving my embouchure. With the way I usually play with mostly top lip, I have trouble hitting a concert G above the staff with loads of pressure, but with what I did part of practice today I could hit a double G with no pressure at all (but couldn't play low at all). I've been trying so hard to improve my range over time and use less pressure, but to no avail... Should I try the new embouchure and try to work my way low? or should I stick with what I've been doing? Thanks for any help in advance..
P.s. I can also play down to a petal concert C with my old embouchure.
