Kristen Thompson, co-founder of Digital Clarinet Academy, talks through common issues facing clarinetists in the altissimo. Under-voicing, over-voicing, biting, double-lip embouchure, reed strength.
Problem #1: Undervoicing
Symptoms:
when entering the altissimo, the pitch that we’re expecting to hear is preceded by something like a grunt or fuzzy tone
Causes:
Incorrect tongue position (should be high and forward).
Inadequate air support.
Solutions:
Ensure proper tongue placement.
Check and improve air support. It’s a misconception that altissimo requires less air. In fact, it needs both faster air and more focused air.
Use the left thumb to gently push against the top teeth (but without biting).
Increase mouthpiece for better tone production.
Problem #2: Overvoicing:
Symptoms:
Getting notes higher than intended: a squeak, or over-shooting altissimo E to super-altissimo A.
Causes:
Incorrect tongue position (over-positioning).
Embouchure issues (jaw pressure).
Solutions:
Check and maintain proper tongue position.
Verify and adjust embouchure, avoiding excessive jaw pressure.
Experiment with double lip embouchure or adjusting mouthpiece placement.
Reeds:
Using a harder read may make it easier to play in the altissimo. However, that reed may make the lower registers more difficult to control.
