Guitar chord library

Every root, every quality — real fretboard shapes.

Look up any major, minor, diminished, or augmented triad by root. Each page shows the chord's real notes and every playable shape across the neck, computed live from the same engine that powers the interactive fretboard — not a fixed diagram library.

The chord library

Explore guitar chords by quality and root.

Every link below is a real, indexable guide generated from the same music engine that powers the interactive fretboard.

Major

Stable and bright - the most common triad quality, and the default reading of a bare chord letter ("C", "F", "Bb").

12 roots

C Major Db Major D Major Eb Major E Major F Major F# Major G Major Ab Major A Major Bb Major B Major

Minor

Darker than major, built by flattening the 3rd a semitone. Written with a lowercase "m" (Cm, F#m, Bbm).

12 roots

C Minor Db Minor D Minor Eb Minor E Minor F Minor F# Minor G Minor Ab Minor A Minor Bb Minor B Minor

Diminished

Two stacked minor 3rds, landing on a flatted 5th - tense and unstable, almost always resolving somewhere else.

C Diminished Db Diminished D Diminished Eb Diminished E Diminished F Diminished F# Diminished G Diminished Ab Diminished A Diminished Bb Diminished B Diminished

Augmented

Two stacked major 3rds, landing on a sharpened 5th - symmetric and harmonically ambiguous.
