Weeks 11-12 · breath planning
Breathe with your ribs, not your shoulders.
Per bel canto and EBVP, sustained phrasing depends on costal (rib-expansion) breathing rather than clavicular (shoulders rising). The detector watches your shoulder line for ~15 seconds — if it stays still while you breathe, you’re in the diaphragm pattern that supports verse-length phrases.
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; arms relaxed at your sides.
- Tap Start, then take 3–4 slow breaths over 15 seconds. Try to keep your shoulders still — let the lower ribs do the work.
- Pass = costal pattern detected (low shoulder motion). 3 of 4 trials passes the session.
