Don't take our word.
Move something.

These are the studio's own controls, running on a sample loop. No file, no account, nothing to install — drag them and see what they do to a song.

01

Transpose

Too high to sing? Move the whole song until it sits where your voice does.

Live
A minor original key

Notice the spelling change — go up one and you are in B♭ minor, so it is G♭ and D♭, not F♯ and C♯. In the studio the recording moves with you: the audio is pitched into the new key while the tempo stays exactly where it was, so the grid still lines up. Three semitones either way — more about the key changer.

02

Slow it down

Take the tempo off until your hands can keep up.

Am
1.00×96 BPM

The count, the chord changes and the whole grid slow down together. Pitch stays exactly where it is — a song at half speed is still in the same key, just slow enough to learn. More about the slow downer.

03

The beat grid

Not a list of chords — a map of the song. Every block is as wide as the chord is long, over the song's own bar lines.

Playing Am
Lasts 5.0s
Bar 1 · beat 1
drag to scrub

Two bars of A minor is a wide block; the last two changes are half a bar each and look it. In the studio the bar lines come from the song's own beats, so the 1-2-3-4 holds through a quiet intro — and tapping a block jumps the audio there.

04

Capo

Same song, easier shapes. Slide the capo along the neck and watch the barre chords turn into ones you already know.

Live
No capo

You finger E — it sounds as E.

Try fret 4: the song still sounds in E, but you are playing C, G, Am and F. The studio prints exactly this above the chords, so you always know which one you are looking at — more on capo and transpose.

05

Your instrument

Pick a chord. Pick an instrument. That is the fingering.

Majors, minors, sevenths, sus, sixths, diminished and augmented — on every root. In the studio this is the chord playing right now, with the next one beside it and a countdown to the change. Browse them one at a time in the chord library.

Staff notation

The notes on a stave,
not just a chord name.

Most chord sites stop at the letters. Every chord here is also drawn on a treble stave — the notes themselves, spelled the way a musician would write them.

06

Read the chord

Pick one. The stave shows its notes, in the order they stack up from the root.

Live

The spelling follows the chord, not the keyboard. A minor is A, C, E; E flat major is E♭, G, B♭ — never D♯, F double-sharp, A♯, which is the same three sounds written so that nobody can read them.

What the stave shows

A treble clef, five lines, and the notes of the chord stacked upwards from its root: one note head each, ledger lines where they run past the stave, and the note name printed underneath.

It is the chord, not a transcription of the recording — no rhythm, no melody line, no tablature. In the studio the stave sits beside the guitar, ukulele and piano diagrams and redraws on every chord change, so the notation moves with the song.

One chord to a page, with the same stave and the same shapes: C major, A minor, G major and the rest of the chord library.

In the studio

The rest of the practice room.

The parts you cannot fit in a demo box, but reach for the moment you sit down with a song you actually want to learn.

Section looping

Ring the two bars you keep fluffing and play them round and round until you don't.

A click on the song's own beats

Not near the beat — on it. The metronome is placed on the same grid the chords sit on.

Count-off

Four beats before it starts, so you come in on one instead of chasing it.

Song and click, separately

Bring the track down and the click up while you learn it, then swap them back.

MIDI export

Take the detected chords into your DAW as a MIDI file and build on them.

Printable chord sheets

A clean chords-over-lyrics page to print, or keep on the stand as a PDF.

Tuner

Guitar, bass and ukulele, standard or dropped, right in the browser.

Beginner to expert

Ask for plain triads while you learn the song, then turn the full harmony back on.

Jump anywhere

Tap a chord, a bar or a line of lyrics and the song is there, still in time.

Keyboard shortcuts

Space to play, arrows for the next bar or the next semitone, 1-2-3 for the levels.

Some of these are newly built and still settling into the studio.
