Closure Symptoms
Insufficient ClosureBreathy
The vocal folds aren't closing properly — either too breathy or too pressed.
SqueezeSqueeze
The glottis is squeezed too tight, blocking airflow and making the voice tight and effortful.
Unstable ClosureWobbly
Closure flickers between tight and loose — the voice flips between airy and solid, like a loose connection.
Register Symptoms
Register BreakBreak
When moving from low to high notes, the voice suddenly "jumps" at a certain point without a smooth transition.
Insufficient ThinningHeavy
The vocal folds don't thin out in time when singing high notes, leaving the voice stuck in a "thick" state.
Unstable ThinningHi Wobble
In the high range the folds flip between thin and thick, so the tone alternates between easy and effortful.
Insufficient ThicknessThin
In the low range the vocal folds are too thin and lack mass, making the voice thin and weak.
Unstable ThicknessLo Wobble
In the low range the folds can't hold a steady thickness, so the voice alternates between solid and faint.
Resonance Symptoms
Insufficient DepthShallow
Resonance stays at the front of the mouth — the voice is pale and shallow, lacking a sense of space and depth.
High LarynxHigh
The larynx rides up as you sing, making the voice tight and sharp, as if it were being lifted.
Tongue RetractionRetracted
Tongue retraction means the root of the tongue pulls backward, blocking the passage behind the throat. The sound can't get out, so it becomes muffled.
Unstable Tongue PositionWobbly
The tongue drifts forward and back, so vowel color and resonance wobble along with it.
Insufficient CompressionWeak
A well-compressed voice is like a flashlight — the beam is focused and reaches far. A voice with insufficient compression is like a bare light bulb — the light scatters and doesn't carry.
