The chords, explained

Every chord has a reason.

Play your melody and watch the harmony build underneath — each chord shows its function (T · S · D), its degree, and a plain-language why.

Bar by bar

Everyone gives one scale for the whole song.
We hear the right one for every bar.

When your song changes color, the harmony moves with it — so the chords stay right even where other tools fall flat.

One scale, the whole song

Five ways to hear it

One melody. Five musical worlds.

The same melody, harmonized five ways — from clean classical to smoky neo-soul. Pick the world that fits your song.

Classical

Clean voice-leading, timeless cadences.

Jazz

Extensions, ii–V–I, smoky sevenths.

Bright, singable, radio-ready.

?

Cinematic

Wide, emotional, film-score color.

?

Neo Soul

Lush, warm, unexpected turns.

On your instrument

Everything you need to play it.

Not just chords. A bass line, a solo to borrow, and five real guitar shapes for every chord — each note with a role and a reason.
