Should Your Throat Vibrate When Singing?

The first thing I want to point out is that your throat is going to vibrate whether you're singing from your diaphragm or not. Vibration is normal, as resonance is what creates the fullness of the sound while singing. Tension however, is not, which is what often is present when we're not singing from the diaphragm.

Why do I feel a vibration in my throat when I sing?

Spasmodic dysphonia, or laryngeal dystonia, is a disorder affecting the voice muscles in the larynx, also called the voice box. When you speak, air from your lungs is pushed between two elastic structures—called vocal folds—causing them to vibrate and produce your voice.

How should your throat feel when singing?

This tight sensation isn't what you want for singing. It may take you a while to feel the difference between pushing down and dropping. The correct sensation is to feel your tongue moving forward and stretching the space between the parts of the larynx so that the bottom part of the larynx drops.
