Tutorial

Getting Started

Choose your instrument — click an instrument card at the top of the screen.

Pick a tuning — use the preset dropdown in the left sidebar, or customize each string individually.

Explore the fretboard — every circle shows the note name. Strings run left to right, fret numbers run across the top.

Select a scale — go to Scales in the sidebar, pick a key and scale name. Colored notes appear on the fretboard.

Find chords — go to Chord Finder. Click any chord card to highlight its shape on the fretboard.

Identify notes — go to Note Detective. Tap notes on the fretboard or pick them by name and we'll name the chord.

Color Legend
