Find a chord from piano notes

Select notes across two octaves. The finder compares the distinct pitch classes with a library of common triads, seventh chords, suspended chords and ninth chords. The lowest selected key determines the bass. A complete match is shown before candidates that need one additional tone. A collection of notes can support several names, especially with suspended chords or missing roots, so the tool lists alternatives instead of claiming one universal answer. Register and musical context still matter when choosing a useful chord name.

Using the Piano Chord Finder

Select the notes under your fingers to compare possible chord names. Include the actual bass note if you want the result to describe the inversion you are playing.

Instructions

Select keys across the displayed C3–B4 range. Tap a selected key again to remove it.
Read the matching names and alternatives. Hear selected notes plays the notes together; Stop sound ends playback.
Use Clear notes before entering another chord. Keyboard users can focus a piano key and use Space or Enter to toggle it.

Understanding a chord match

C, E and G match C major. With E as the lowest selected pitch, the same chord can be labeled C/E. The finder compares distinct pitch classes with common chord patterns; different voicings or incomplete chords can support more than one useful name.

What to do if no clear chord appears

Choose at least three distinct note names. Selecting the same note in two octaves adds register but not another chord tone.
Check for an accidentally selected adjacent key. Clear notes is the quickest way to start again.
Read missing-tone suggestions as possibilities, not proof of a chord. The tool's library does not include every possible harmony.

Use the name that fits the bass and the musical context. Listening to the chord before and after it can help resolve an ambiguous result.
