What Is Chest Voice, Mixed Voice, Head Voice And Falsetto?

In this video, Los Angeles-based vocal coach Rachel Burnley breaks down the various vocal registers—chest voice, middle voice, head voice, and falsetto—and explains how singers navigate between them. She emphasizes that while it is important to understand these distinct registers, singers should avoid thinking of them as completely separate compartments, as a healthy vocal approach involves blending them rather than singing exclusively in one isolated register. Mechanically, the vocal cords adjust depending on the desired pitch: lower notes require a thicker cord state, while higher notes require the cords to thin and shorten. Burnley compares this vocal cord adjustment to the strings of a guitar or piano, where thicker strings produce lower pitches and thinner strings produce higher pitches.

Burnley then details the specific characteristics of each register along the vocal range. The chest voice occupies the lower range, where the vocal cords remain thicker. As pitch rises, singers transition into the middle voice, which functions as a blend or mix of both chest and head voice. Moving higher leads into the head voice, which relies predominantly on the thinned vocal cords while letting go of the chest resonance. Beyond head voice lies falsetto, which occurs when there is a breathy disconnection in the vocal cord seal, resulting in an airy, non-connected tone that singers typically use as a stylistic effect rather than a primary tone.

To illustrate these concepts, Burnley conducts a vocal demonstration using an "a" vowel sound to show how to seamlessly blend and move through the different registers. She demonstrates starting in chest voice, allowing the vocal cords to thin as she mixes into middle and head voice, briefly showing the disconnected quality of falsetto, and then mixing back down into chest voice. The ultimate goal of these vocal exercises is to help singers learn how to connect all parts of their range and transition smoothly through their registers without harsh breaks.
