Lessons

Twelve tracks. Ten levels each.

Every lesson is fitted to your range, runs 60–150 seconds, and starts with the trainer singing the first note in your key. Score 80 % to open the next level; strain caps the score at 79 so the only way up is a free voice.

Skill tracks

From the first glide to a connected mix.

Warm-up glidesLip trills and hums on held notes, scales and gentle sirens. Moves by step only.

Pitch accuracyLand the note, hold the centre, correct the direction you drift.

Chord notesArpeggios — the notes of the chord, up and down, key by key.

Breath and sustainLong holds, steady tone, the swell of a held note.

VowelsAh, ee, oo and the ladders between them, fitted to each note for your voice type.

AgilityRuns and quick patterns, cleanly separated.

Short notes and startsStaccato, clean onsets, no scoop and no late start.

LeapsIntervals of growing size, both directions, inside a phrase.

Loud and softDynamics without pressing; messa di voce on one note.

Break and rangeSlides through the passaggio, stretching the top and bottom gently.

Mix voice"ng" sirens, light "nay" patterns, cry slides and a phrase across the bridge. Credit above the bridge needs a connected mix.

Ring and placementForward resonance and twang, where your style wants it.

Daily

Today's plan

One lesson a day picked from your progress, with a warm-up chosen for it — the mix warm-up whenever the lesson crosses your bridge, "free the voice" whenever strain has been showing.

Before you sing

Warm-ups with a ready check

Free the voice, Mix warm-up, Range warm-up. Each exercise comes in a classical and a contemporary version (Garcia, Marchesi, Lamperti, Miller, Estill, CVT, SOVT…), names its strain risk, and ends with a 15-second check: three easy "ah" starts and one slow siren through the bridge.

Built from you

Passaggio AI lessons

After about ten lessons the app has enough evidence to establish a weak area — a specific note, a leap, a vowel, a bridge crossing or a habit — and generates a targeted lesson for it, inside your range. It retires once you've kept it clean five times in a row.

Breath

Breath and release

Loosening moves, counted breathing, a steady-hiss ladder, a long soft hold with your best times kept, and a placement check.

Style gate

Judged in your style

Declare classical, musical theatre, pop, rock, jazz or folk per exercise. A scoop isn't a miss in pop; belt, breath and twang are only flagged where the style treats them as faults.

Unlocks

80 % opens the next level

A weighted score from note accuracy and research-backed tone components. Nothing unlocks from pushing: strain caps the score at 79, silently.
