Chord identifier
Guitar Chord Finder
Find the name of a guitar chord from the shape you are playing or the notes you already know. Enter frets or note names to see matching chord names, intervals, notes, and slash-bass suggestions.
Fretboard input
Click the frets you are playing
Set each string to muted, open, or a fret from 1 to 12. The lowest sounding string is used as the slash bass note when it changes the chord name.

Identify an unknown guitar shape
Click the strings and frets you are holding down to name a chord shape you found by ear, in a tab, or while writing.
Turn notes into chord names
Select notes from a melody, piano voicing, or theory exercise and see the likely chord names without entering a full diagram.
Check slash chords and inversions
Use the lowest sounding guitar string to understand when a shape is better named as C/E, D/F#, or another bass-note inversion.
Reverse chord lookup
Find chord names from guitar shapes, notes, and inversions
This reverse guitar chord finder is for the moment when you have a fingering, tab shape, or set of notes but do not know the chord name. Instead of starting with Amaj7 or B7, you start with the sound under your fingers.
Use the right input for the information you have
Use fretboard input when you know the guitar fingering or chord shape. Use notes input when you know pitch names from another instrument, a melody, a piano voicing, or a theory exercise.
Chord names still depend on musical context
The same notes can sometimes create more than one valid chord name. The finder ranks exact matches first, then uses the bass note and common chord qualities to keep practical names near the top.
FAQ
Chord finder questions
What chord am I playing on guitar?
Click the frets and strings you are holding down, including open or muted strings. The tool reads the notes in your shape and suggests the most likely chord names.
How does this guitar chord finder work?
It converts your selected frets or note names into pitch classes, compares them with common chord formulas, and ranks exact note matches before possible partial names.
Can I find a chord from notes only?
Yes. Use Notes mode to select note names such as A, C#, E, and G#. The finder ignores duplicated notes and returns chord names that match the selected pitch classes.
Why do I see slash chords like C/E?
When you use fretboard input, the lowest sounding string is treated as the bass note. If that bass note is not the chord root, the result is shown as a slash chord.
Why can the same notes have more than one chord name?
Some note sets can be interpreted from different roots. For example, A C E G can be named Am7 or C6 depending on the musical context and bass note.
