I like Kermit the Frog, but when I sing, I do not want to sound like him!
This unhealthy sensation that sounds like Kermit is when there is throat constriction present, which causes us to feel the throat is tightening, closing or pinching.
This will not be comfortable and does result in:
Vocal fatigue,
Soreness,
Loss of movement in the range,
Restriction of volume, power, and emotional expression.
