Guitar chords with diagrams, notes and formulas
Find any guitar chord by its root and type, see the diagram with the finger for each string and hear how it sounds. There are 102 chords on the 12 notes: everyday major and minor chords, sevenths, suspended, diminished and augmented chords.
Each chord also has its own page with its notes and formula, all its voicings (open and barre), where each note sits on the fretboard, its inversions, the keys it belongs to and the progressions that use it.
The tool opens right here in your browser when the page finishes loading.
Which chords are in the library
The chord types you play every day are on all 12 roots; the less common ones, only on some:
- On all 12 roots: major, minor, dominant seventh (7), major seventh (maj7), minor seventh (m7), sus4 and diminished.
- On 8 roots: sus2 and augmented, on C, C♯, D, E, F, G, A and B.
- Only on C: C add9 (Cadd9) and C major sixth (C6).
How to find and hear a chord
Pick one of the 12 notes and you get every chord built on it, each with its diagram in standard tuning (E A D G B E) and the fingering. When a chord has more than one voicing, you can switch between them on the same card.
In the “Search chords” box you can type a chord the way you write it, such as Am7, Bb or F#m.
“Play” strums the chord. It uses piano samples, not a guitar sound, so it is there to check the notes. “Open on the fretboard” sends the voicing to the interactive fretboard, and “Chord page” takes you to the full chord page.
What each chord page includes
- Voicings: the ones in the library and, for the chord types that allow it, the movable barre shapes (E shape and A shape), each written as a list of frets.
- Notes on the fretboard: where each chord note sits on the six strings, from the nut to the 12th fret.
- Formula and intervals: which interval each note makes with the root (third, fifth, seventh…).
- Ukulele and piano: the ukulele shape and the keys you play on the piano.
- Inversions: root position and every inversion, with its slash-chord symbol (C/E).
- Keys and progressions: the major and minor keys the chord belongs to, with its degree in each, and typical progressions written in those keys.
- Related chords: its relative, its parallel major or minor, its dominant seventh and its neighbors on the circle of fifths.
Frequently asked questions
How many guitar chords are in the library?
102: the seven most common types (major, minor, 7, maj7, m7, sus4 and diminished) on all 12 notes, sus2 and augmented on 8 notes, and add9 and sixth chords on C.
What does a chord formula mean?
It tells you which intervals make up the chord, counted from the root. 1-3-5 is a major triad (C, E and G in C major), 1-♭3-5 a minor triad and 1-3-5-♭7 a dominant seventh.
Why do the chords sound like a piano?
Because the library uses piano samples for every chord. The diagram and the fingering are for guitar; the sound is there to check the notes, not to imitate a guitar.
Is it C♯ or D♭?
It depends on the key. Each chord page uses the most common spelling for its chord type (D♭ major, but C♯ minor) and explains when the other spelling is used.
How do I find out which chord I am playing?
Mark the notes on the chord namer and it gives you the chord name. If you want the chords of a recorded song, upload it to Chord AI.
