What is clarinet tonguing?
Anchor tonguing occurs when the tip of the tongue is anchored behind the lower teeth and the articulation is created with the middle of the tongue touching the reed. Ideally, the tip of the tongue touches just below the tip of the reed to interrupt the vibrations of the reed.
Why does my clarinet sound scratchy?
There are many reasons for having a fuzzy or airy tone on the clarinet, but it's generally possible to isolate the cause. The most common problems that cause a fuzzy sound are due to the mouthpiece or the reed, incorrect embouchure or air support, low tongue position or a leak or crack in the clarinet.
