When buzzing, how should the lips behave?

• A. The lips should stay relaxed while the corners stay firm, not too tight or too loose.
• B. The lips should be pressed tightly to create more pressure.
• C. The lips should be completely slack with no control.
• D. The corners should move independently to shape the sound.

Answer: (A)

Buzzing works best when the lips form a light, flexible barrier that can vibrate with the air. Keep the lips relatively relaxed, but the corners should stay gently firm to create a small seal. This balance lets air pressure make the lip tissue buzz smoothly and steadily. If the lips are pressed tightly, extra resistance dulls the vibration; if they’re completely slack, you lose control over the buzzing; if the corners move independently, the vibration becomes uneven. So, relaxed lips with firm corners is the ideal approach.
