Figuring out chords by ear takes time. The Chord Finder analyzes an audio file and shows the chord progression so you can start learning a song much faster. It is not perfect, but it gives you a solid foundation to refine by ear.
How to find chords
- Open the Chord Finder page.
- Drop an MP3, WAV or M4A file.
- Once the analysis finishes, chords appear on a timeline. Each chord shows its name (C, Am, G7, etc.) and a guitar diagram.
- Press Play to listen along and check whether each chord sounds right.
- Note any corrections as you go.

What works well, and what does not
- Works well: Acoustic pop, ballads, folk. Fewer instruments and simpler chords mean higher accuracy.
- Moderate: Band arrangements (drums + bass + guitar). Major and minor chords are usually right, but voicings like sus4 or add9 may be missed.
- Difficult: Jazz (extended harmony, tension chords), EDM (synth pads blur the harmony), orchestral. Treat the results as a rough guide.
After you have the chords
- Use Speed & Pitch to slow the song down and practice along at a comfortable tempo.
- Turn on the Metronome and practice chord changes on beat.
- Use BPM & Key Detector to find the key and tempo before you start.
Good to know
- Automatic chord detection is never 100% accurate. Always verify by ear.
- Creating and distributing chord sheets for copyrighted songs may raise copyright issues. Use for personal practice only.
FAQ
Does it detect every chord perfectly?
Simple progressions (pop, ballads) are detected with high accuracy. Jazz voicings and extended chords may be less accurate — use the results as a starting point and verify by ear.
Does it work for piano songs?
Yes. The chord detection analyzes harmony regardless of instrument, so it works for piano, guitar, ukulele and more.
Can I save the chord chart?
You can copy the results as text or take a screenshot to save.
