Scales

Every scale, every key, the whole neck

Not a box to memorise. The whole map at once, colored by what each note does, so you can see why a scale sounds the way it does.

The Fretbound scale atlas: C minor pentatonic across the full neck, every note color-coded by interval, with the scales it relates to listed below

This is the atlas, live in the app. Pick any of twelve roots and any scale, from the pentatonics and the modes to blues, harmonic and melodic minor, and the whole neck lights up, root to fifteenth fret.

Roots, thirds, fifths and sevenths each carry their own color, so the shape of the SOUND is visible: you can see where the blue note sits, which tone makes Dorian brighter than minor, and why the pentatonic never lands on a clash.

How scales relate

Every scale knows its neighbors.

Every scale page knows its neighbors: the pentatonic that lives inside the natural minor, the one note blues adds, the major scale wearing a different home. Understanding arrives by comparison, one tap apart.

Flip the labels from intervals to note names to blank and quiz yourself on the spot. Then let the drills schedule the shapes until they are simply yours.

All of it lives in the app.
