Ever wonder how stage actors project their voices clearly across a 500-seat theater without losing their voice by intermission?
The secret isn't pushing harder from your throat — it comes from an engine located right beneath your ribs.

Meet the Diaphragm

The diaphragm is a large, dome-shaped muscle sitting directly beneath your lungs that separates your chest cavity from your abdomen.
When you inhale, your diaphragm contracts and pulls downward, creating negative pressure that draws air deep into your lungs and pushes your lower belly outward.

How Breath Support Protects the Voice

Vocal support is the technique of using your core muscles to control the release of air so your vocal cords vibrate with steady, gentle pressure.
Think of your voice like a sailboat: your breath is the wind that provides all the power, while your throat is just the sail guiding the direction.
What happens when actors forget to use their core and breathe the wrong way under pressure?
