What chord is this? Select the notes and find out
This chord identifier reads the notes you pick on a piano keyboard or a guitar fretboard and names the chord, with its inversion, its slash bass and the other names the same notes can have. Pick or type a chord name and it works the other way round.
How it works
From the notes you play to a chord name
Step 1
Choose piano, guitar or a name
Use the keyboard as a piano chord finder, the fretboard as a guitar chord finder, or switch to By name when you already have a chord symbol.
Step 2
Select the notes you are playing
Every note sounds as you select it. The lowest one is read as the bass, which is how the tool tells C from C/E.
Step 3
Read the name and listen
See the chord name, the role of each note and the other names for the same notes. Play the chord, or open it in the chord workbench.
What you get
A chord identifier that shows how it reads your notes
Every result lists the notes of the chord and what each one does in it, so you can check the name against what you played.
A piano chord finder across three octaves
Select keys on the keyboard and the chord name appears as soon as the notes form a chord. Each key sounds as you select it, and Play gives you the whole chord.
A guitar chord finder with open and muted strings
Tap one fret per string on a 12-fret neck in standard tuning, the spot left of the nut for an open string, and a selected spot again to leave the string out. Play strums the shape.
A reverse chord finder
Pick a root and a chord type, or type a chord symbol such as Cmaj7, F#m7b5 or G/B, to see its notes on the keyboard and hear it, which is a quick way to check a chord chart.
Inversions and slash chords
The lowest note you select is the bass. E, G and C come back as C/E in first inversion, and a seventh chord played without its fifth still gets its name.
Every name the notes can have
C, E, G and A are C6 from one root and Am7 from another. This chord namer lists the readings, simplest first, and lets you switch between them.
42 chord types and the role of every note
Triads, sixths, sevenths, added-note chords, ninths, elevenths, thirteenths, altered dominants, sus and power chords on all 12 roots. Each note is labeled root, third, fifth, seventh or extension.

FAQ
Chord finder questions
Choose Piano or Guitar and select the notes you are playing. As soon as they form a chord, its name appears along with the role of each note. To look a chord up the other way, choose By name and pick a root and a chord type, or type a symbol such as Cmaj7.
Stack the notes in thirds; the bottom of the stack is the root. F, A and C stack as F–A–C, a major third and a perfect fifth above F, so the chord is F major. Add E♭ on top and it becomes F7. If the stack only works from a note other than your lowest one, the chord is an inversion, and the chord identifier writes it as a slash chord.
A chord is named from its root, and the same notes can be stacked on different roots. C, E, G and A are C6 when C is the lowest note and Am7 when A is. The chord finder shows the simplest reading first, favoring a root in the bass, and lists the rest under Other names.
Yes. The lowest note you select is treated as the bass, so E, G and C are named C/E and described as first inversion. Whenever the bass is not the root, the result is written as a slash chord with the bass note after the slash.
It knows 42 chord types on all twelve roots: major, minor, diminished, augmented, sus2, sus4 and power chords; sixth and six-nine chords; seventh chords including half-diminished and minor-major; added-note chords; ninths, elevenths and thirteenths; and altered dominants. Chords of four or more notes are also recognized when the fifth is left out.
No, it uses standard tuning only: E, A, D, G, B, E. The fretboard covers the open strings and frets 1 to 12, with one note per string. For a guitar in another tuning, enter the notes that sound on the piano keyboard instead.
No. This page names a chord from the notes you select and does not analyze uploaded audio. If you can pick out the notes of the chord by ear or on your instrument, enter them here to get the name.
