Insufficient Thinning

On high notes the folds don't thin in time; the voice stays stuck in the "thick" state.

In One Sentence

When singing high notes, the folds don't stretch and thin in time, so the voice stays stuck in the thick state.

How to Read It

Watch the Fold Balance chart on high notes and see whether the needle moves naturally to the right. If it stays pinned on the left (thick side), the stretch (CT) is insufficient.

Why Does This Happen?

CauseDescription
No transition at the passaggioThe folds aren't stretched in time going from low to high
Habitual pushingAlways "pushing" high notes instead of thinning
Insufficient breath supportNot enough airflow to help the folds stretch

How to Improve

  • Humming: hum "mmm" and feel the folds stretch naturally on high notes
  • Lip trills: "brrr" sliding from low to high
  • Octave slides: glide smoothly within an octave, focusing on the stretching feeling
