Every human voice functions according to specific laws of nature. These laws determine how all instruments—including the human voice—must be built and operated to function correctly. When we align our technique with these natural rules, we unlock a level of freedom that allows us to sing the music we love without limitation.
To understand the voice, it helps to look at a piano. A piano has strings of varying lengths and thicknesses: short, thin, taut strings produce high pitches, while long, thick, loose strings produce lower pitches. Our vocal folds operate on this exact same principle.
We have two basic muscle systems in our larynx that determine how we speak and sing. These systems produce what are commonly known as the two primary registers:
Healthy singing is not about choosing one register over the other, but about developing and coordinating these two muscle systems. When they work in a healthy relationship, the singer experiences specific sensations:
When we know, understand, and follow the rules of nature, we are set free from the struggle of "making" a sound. Instead, we allow the muscles to do what they were designed to do. This coordination is the key to making all sorts of healthy, "cool" sounds and enjoying a lifelong relationship with your voice.
