I was so glad when I read this post! I was practicing my clarinet and had a hard time getting the right tone and air that I needed, so I looked on the internet and came across your site! I then realized that I was concentrating on my fingerings and notes so much that I wasn't so focused on my embouchure. Embouchure is so imporntant so I'll make sure that I'll play a scale and concentrate fully on my embouchure. Thanks so much!
