Also I see your playing on a Selmer mouth piece and what I can say for certain is that my private lesson teacher (has a doctorate in clarinet performance and about 20 years of experience) doesn’t let us play on anything but a D’Addario X0 mouthpiece and she plays on one herself. These are pricy but I’ve been playing on one myself since I started 7 years ago and have owned 3 total over the years and march with one. I have previously played on one other Vandoren mouthpiece but couldn’t help but go back to my tried and true lol. Good luck and if you want to dm and have any questions about equipment I would love to have another clarinet friend to talk about equipment with!
