The Epiglottic Funnel: Why Singing Can Suddenly Feel Easier

Many singers assume that producing a stronger voice requires more breath, more volume, or more muscular effort. In lessons, I often find the opposite.

When the space immediately above the vocal folds becomes more efficiently focused, the voice can suddenly feel clearer, stronger, and easier. Students who were pushing for volume may discover that the sound carries with less effort. Notes may become steadier, and the throat may feel less involved.

I describe this coordination as the epiglottic funnel.

What Is the Epiglottic Funnel?

The epiglottis is a small, leaf-shaped structure located above the vocal folds. During efficient singing, the surrounding entrance to the larynx can form a narrower, funnel-like space. Voice researchers commonly describe this as epilaryngeal narrowing or aryepiglottic narrowing.

This does not mean squeezing the entire throat or consciously forcing the epiglottis into position. It is a coordinated adjustment that can help concentrate the sound’s acoustic energy before it travels through the rest of the vocal tract.

The epiglottic funnel focuses acoustic energy immediately above the vocal folds while the surrounding vocal tract remains open and responsive.
