Lungs are the engine. Train them.
Breath capacity directly drives vocal power, sustain, and stability. 19 techniques with timed phase visualizers — box breathing, diaphragmatic, lip trills, sustained phonation, coherent-rate, and more. Includes maximum phonation time (MPT), S/Z ratio, and sustained breath capacity (SBC), with why-it-matters explanations baked into every technique.

Each mode owns a clear job. You can switch between them mid-session without losing your place.
Box breathing
Four-phase rhythm visualiser.
Diaphragmatic
Slow exhale with phase coaching.
Sustained phonation
MPT measurement on a vowel.
