Resonance is the heart of vocal color.

(But what does that even mean, if you're not a singer? Here's where you'll find out!)

In this excerpt from Singing for Non-Singers, soprano Heidi Vass breaks down how exploring resonance — and specifically the head voice — can completely reshape the way you think about singing. Through gentle sighs and octave-leap exercises, she helps you connect to vibration in the upper register, opening the space for a free, ringing tone that feels effortless yet expressive.

Even if you’ve always thought of yourself as a “non-singer,” Heidi shows that the human instrument is capable of endless variation. By training your awareness of resonance, you can bridge styles, strengthen confidence, and discover the joy of using the instrument you were born with.
