We ran “Gone With the Rain”, a sad country song made here, through the Chord Finder.

The key, and a palette of six chords: D, A, G, Em, E and Bm.
The verse rocks between D and A, and G lands at 0:16. Press any chord to hear that spot.
E is not in D major, but country leans on it to pull back to A. The finder hears it anyway.
What it reads and what you get.
Drop, play, copy.
Drop an MP3, WAV, M4A or FLAC file onto the box, up to 20 MB.
Press play and each chord lights up as it sounds. Press one to jump there.
Copy the chord names, save them as MIDI, or start a new song in the same key.
From a song you love to the chords under your fingers.

Get the chords of a song before you look for a chart, then play along at full speed.

Find the key and chords of a new song in minutes, then write your own chart.
We also ran “Corner Booth”, a jazzy lofi beat. Here is the honest result.

Jazzy sevenths, a walking bass and brushes give the finder a lot to sort out.
The main chords are right, with quick passing ones between. Keep the ones that last a bar.
Pull out the vocals with the Vocal Remover first, and the chords come out clearer.
One reads chords from a song. The other writes new ones.

Major and minor chords on all twelve notes. A seventh or a suspended chord shows as its plain major or minor form, which is the part you play first anyway.
Very good on songs with clear guitar or piano, like “Gone With the Rain” above. Busy mixes with jazz chords, heavy bass or effects are harder: see “Corner Booth”.
No. It needs an audio file on your device, such as an MP3 you bought or a song you made.
No. The chords are worked out in your browser and we never get the song. Close the page and it is gone.
MP3, WAV, M4A and FLAC up to 20 MB, and OGG in most browsers. A clear recording of guitar or piano gives the cleanest chords.
Load Gone With the Rain from the button under the drop zone. It reads as D major, with D, A, G, Em, E and Bm across the song.
Press Download MIDI and drag the file onto a track in your music app, or press Copy chords and paste the names into a chart or a note.
