Chord Finder
Music theory shouldn't feel like a math test. If you stumble onto a lush, jazzy grip on your guitar or piano but have absolutely no idea what to call it, plug it in here.
Stop arguing with your bandmates over whether it's a minor 7 flat 5 or a half-diminished chord. Use this reverse chord finder and piano chord identifier to get the exact nomenclature instantly.
Identify Chords by Notes
By visualizing the intervals and extensions on our music theory chord calculator, you can drop the textbooks and start actually understanding the harmonic architecture beneath your fingers. This guitar chord namer is an indispensable cheat code for transcribing songs, voicing jazz standards, and writing vastly better chord progressions.
Instant Audio Playback
Don't just read the chord formula—hear it. Hit the play button on the dashboard, or tap any chord pill in the dictionary, and our built-in synth engine will instantly strum the voicing. It's the fastest way to woodshed new voicings and train your ear to recognize those spicy 13ths and diminished extensions.
Master Inversions and Slash Chords
Playing a C major over an E bass? The engine instantly recognizes classic slash chords (C/E) and maps out the exact inversion position. If a voicing is ambiguous (like C6 sharing the exact same keys as Am7), the dashboard automatically resolves the enharmonic equivalents so you always know your options.
Chord Finder FAQ
How do I identify a piano chord?
Simply click the keys on the virtual piano that you are playing. The tool will analyze the intervals and tell you the exact name of the chord, including complex extensions like 9ths and 13ths.
What is a chord inversion?
An inversion occurs when the lowest note (the bass) is not the root note of the chord. For example, a C major chord is C-E-G. If you play it as E-G-C, it is still C major, but in the first inversion (written as C/E).
Does this work for guitar chords?
While the interface uses a piano keyboard, music theory is universal. A C Major 7 chord contains the notes C, E, G, B regardless of whether you play it on a piano or a guitar.
Why does my chord have multiple names?
In music theory, chords can be enharmonically equivalent depending on context. For example, C6 (C-E-G-A) uses the exact same physical piano keys as Am7 (A-C-E-G).
