Why use a chord detector?
Learning how to play a song by ear takes years of practice. If you find a beautiful piano loop or hear a song on the radio and want to know exactly how to play it, trying to guess the chords can be extremely frustrating.
Our chord detector takes any audio file and automatically writes out the chord progression for you. It is the ultimate shortcut for covering songs, remixing, or just learning music theory from your favorite producers.
How to extract the chords
Upload the song you want to analyze. The algorithm scans the harmonic frequencies of the track and identifies the major and minor chords being played at every specific second.
It will display a scrolling timeline showing exactly when each chord changes. You can play along with your guitar or piano right at your desk, skipping hours of frustrating trial and error.
Frequently Asked Questions
Does it show complex jazz chords?
The engine focuses on the fundamental major, minor, augmented, and diminished triads. It might simplify very complex 11th or 13th chords into their root triads to keep things readable.
Can I export the chords as MIDI?
This specific tool only displays the chord names visually on the timeline. If you want to actually export the notes, you should use our Audio to MIDI Converter tool instead.
Why is it struggling with a heavily distorted guitar?
Heavy distortion adds massive amounts of extra harmonics and overtones to the audio. This creates a wall of sound that makes it incredibly difficult for the algorithm to pinpoint the original fundamental chord.
