New mouthpiece and now the corners of my mouth get tired
Hiii two weeks ago I switched from a Yamaha 4c to a Meyer 5M. I’ve been practicing an hour almost every day to get used to the new mouth piece and I thought I started to get the hang of it but now the corners of my mouth get tired and I start to let out air after a short while. Like if I play continuously for about a minute I can feel the strain.
Is it just because I’m still getting used to it after two weeks or am I straining my mouth somehow by doing something wrong?
I also switched from a Vandoren ZZ 2 reed to a Vandoren classic 2 reed because I was recommended that would be a better fit with the Meyer 5M.
I’ve been playing the Yamaha 4c for about two years.
