For singers · invite-only, on purpose

The song, mapped. Your voice, measured.

Vocal Booth draws every song note by note from the real recording — then measures it against your range, so you know where it sits comfortably, where it stretches you, and what to do about it.

The map

Drawn from the record you actually love

A songbook gives you someone's transcription. Vocal Booth listens to the recording itself.

Learn · Meet it → Map it → Sing it

Every word, where it sits in your voice

The map shows each note's register — chest, mix, or head voice — which words carry the tune and which just color it, and where to breathe, with a countdown so the breath actually happens.

  • A guided three-act flow per song
  • Breath marks that count down
  • Reading Mode for the whole song at once
Two mapped phrases from Wonderwall: note bars over each lyric word, register ranges labeled per line, and a 'breathe · 1.3s' marker between them
Reading Mode: the song as a full-screen, auto-spaced word-by-word timeline, each word under its note
The map, phrase by phrase — and Reading Mode when you want the whole song at once.

Two songs, the same singer. Vocal Booth's own words, verbatim.
Calibrate once · about 45 seconds

Two sirens, and every song is honest with you

Slide your voice low, then high — two guided glides, about 45 seconds. That's calibration. From then on, every song reports how it sits in your voice, not some average singer's.

  • A plain verdict per song — comfortable, a stretch, or out of reach, and why
  • How hard it leans on the hand-off between your low and high voice — the spot teachers call the passaggio
  • The hardest moments named, and a key shift suggested when a song needs one

A stretch is a measurement here, not a verdict on you.

The coaching

Coaching drawn from the song itself

Pull up a song and read the brief Abigail wrote for it — what this song actually asks of a voice, and the few moments worth your attention.

Drawn from the recording, not from thin air

Specific, earned, and pinned to the moment

Abigail's coaching isn't generic — every line is drawn from the song's own measured audio and the research behind the technique, then checked against both before it reaches you.

So when she says a phrase runs 11.4 seconds and singers tend to chop it, that came from the recording — and the advice opens right on that spot in the map.

Three coaching-brief cards for Wonderwall, each quoting a lyric and prescribing what to do at that moment — breath planning across a long phrase, keeping verses at speech level, cutting a quiet line with placement instead of volume
A real brief — three of its five moments, each opening on the map where it applies.
The practice room

The hard part has a name. Loop it until it gives.

Everything you need to work a song lives in one tab, next to the map.

Work it, don't just run it

Slow it, loop it, quiet the singer, keep the band

  • Loop any section — or just the hard bit — with a count-in each pass
  • Slow it down to 0.9×, 0.75×, or 0.5× without the pitch dropping
  • Full & Quiet vocal mixes — the original singer loud beside you, or nearly gone
  • Never come in cold — hear your target note first, or hold a steady drone on the song's home note
  • See yourself live — while you sing, your detected note rides the map: on it, flat, or sharp, the moment it happens
Technique library · 16 explainers

Technique as sensation, not homework

Belt, twang, head voice, breath support — sixteen techniques, each taught as what it should feel like, with the mistake described so you can catch it yourself. The musical terms stay, in plain words, so a voice lesson or a choir rehearsal will make sense too.

New to singing entirely? The "Start here" primer, narrated by Abigail, assumes nothing: what your voice physically does, the handful of words the app uses with you, and a one-minute experiment for each idea.

Duets

Two voices, one song? Sing yours.

On a duet, Vocal Booth knows whose line is whose. Pick your part and the map, the reference vocal, and the coaching all follow the voice you're actually singing.

Your library

Practice on the music you love

Your library isn't a preset workbook. Search and add the songs you actually want to sing, or upload your own file — Vocal Booth listens to the recording and measures what matters: tempo, key, range, difficulty, mood. Then it sorts them by what's easiest for you.

Songs are metered, not endless: your account starts with 3, and each one after that is $3. Analysing a track is real work, and we'd rather charge for it than pad the page with ads.

Ear training

Five browser drills — intervals, chords, in-tune detection, pitch matching, and A/B comparison — sharpen the ear the map trains.

Warm-ups & a weekly plan

Guided warm-ups before you sing, and a weekly plan that keeps the fundamentals moving between songs.

Your guide

Meet Abigail

The coaching has a face — and a way of working. She's the expert ear who walks you through every session.

Abigail, the guide who walks you through Vocal Booth
Abigail — your guide · coaching breath support

The expert ear that's honest with you.

She studies the song you're about to sing, and shows you the one thing to work on next.

Most singers don't quit because they lack talent. They quit because no one ever told them, plainly, what to do next — just "sing it again," or worse, "that was great!" when it wasn't. Abigail exists to end that.

Coaches off what's actually there One thing at a time Honest, never inflated

She won't pretend the passaggio isn't awkward or that breath support clicks overnight — the long plateau before the hard parts cooperate is real, and she'll just show you the way through, one repeatable sensation at a time, and she never makes it up.

She says
  • "Let's work on this one phrase."
  • "Feel the buzz move forward — there it is."
  • "That part's genuinely tricky. Here's the way in."
  • "This line sits right on your break — keep it light."
She never says
  • "OMG that was incredible!!!"
  • "Engage your mixed voice."
  • "Just relax, you've got this."
  • "Wrong — do it again."
