About Chordharbor

Chordharbor is a free reference for guitar players. Every chord and scale is generated from music theory, and every fingering is checked by software so that each fretted note belongs to the chord.

How the content is made

Notes are spelled correctly (for example, C♯ major contains E♯, not F). Chord shapes are searched across the fretboard and ranked by how easy they are to play. Guides are written by guitar players and reviewed for accuracy. If you spot a mistake, please tell us.

The app

Chordharbor is made by the team behind Guitar Chords: Tuner & Songs. Chord library, a built-in chromatic tuner that works offline, songs with chords, and a new guitar riff every day.
