Stand stacked. Camera will check.
Per Estill body-use cues, an open ribcage and free jaw/tongue are pre-conditions for any sustained voicing — without them, breath collapses and the larynx grips. Bel canto pedagogy treats this released alignment as the silent first step before any tone.
How it works
- Place your phone or laptop on a stable surface, camera at chest height.
- Stand back about 1 meter so head + hips are both in frame.
- Tap Start and hold a stacked, soft posture for 5 seconds. 5 trials.
- Pass = mean alignment score ≥ 85%. 4 of 5 passes the session.
