Sprint a 100-meter dash in freezing weather without stretching, and you will probably pull a muscle.
Your voice works the exact same way: your vocal folds are two delicate bands of muscular tissue in your voice box (larynx) that vibrate hundreds of times per second.
So what is the safest sequence to wake these tissues up before stepping onto the stage?

Step 1: Alignment and Breath

Before making any sound, your voice relies on steady airflow powered by the diaphragm, the large dome-shaped muscle at the base of your rib cage that pulls air into the lungs.
Stand with feet shoulder-width apart, drop your shoulders down and back, and inhale for 4 counts so your lower belly expands gently.
Exhale on a steady, unvoiced 'hiss' (like air escaping a tire) for 8 to 12 counts to wake up your breath support without throat squeeze.
Once your breath is flowing freely, how do you start making pitch without banging your vocal folds together?

Step 2: Semi-Occluded Vocal Tract (SOVT)

A semi-occluded vocal tract (SOVT) exercise is any vocal drill where you partially narrow the mouth opening, such as through a lip trill, a hum, or blowing through a straw.
In the 1990s, voice scientist Dr. Ingo Titze demonstrated that narrowing the mouth creates acoustic back-pressure, which reflects sound energy back down toward the larynx and cushions the vocal folds from slamming hard against each other.
