Finds simplified chords — the 24 major and minor chords. 7ths and extended chords show as the basic chord underneath (G7 → G), which still sounds right played along. Works best when a guitar, piano or other chord instrument is clearly audible.
How to Find the Chords of a Song
- Upload a song. Drag an audio file into the drop zone or click to choose one. MP3, WAV, M4A, OGG and FLAC all work, and the file stays on your device.
- Let it find the chords. The tool analyses the recording and returns a chord timeline with a confidence rating on every chord, the key of the song, and a diagram for each chord.
- Play along. Press play. The current and next chord are highlighted as the song plays, with the chord diagram for the one sounding now.
- Check and correct. Tap any chord to hear it or jump to it in the song. If one sounds wrong, pick a suggested alternative or type the right chord, such as G7.
- Set your capo. If the guitarist plays with a capo, set capo mode to that fret to see the shapes to play instead of the sounding chords.
- Take the chords with you. Copy the chords as text, or open them in the Chord Progression Player to loop and practise the progression.
About This Online Song Chord Finder
Guitar Tool Hub's free song chord finder (also called a chord detector, chord recognizer, or 'what chords are in this song' tool) finds the chords of any song or audio file right in your browser. Drop in an MP3, WAV, M4A, OGG, or FLAC and it listens for which notes sound together over time, matches them against the 24 major and minor chords, and returns a chord timeline with a confidence rating on every chord, the key of the song, and a diagram for each chord. Press play and the chords light up as the song plays. It shows simplified chords — a G7 appears as G — so every chord is one you can strum along with, and any chord can be corrected with a tap. Nothing is ever uploaded.

Frequently Asked Questions
Upload the song to the Song Chord Finder. It listens to the recording in your browser and returns a chord timeline: every chord, when it starts, and a confidence rating, plus a chord diagram for each one. Press play and the current and next chord light up as the song plays, so you can strum along straight away.
The Song Chord Finder detects simplified chords: the 24 major and minor chords. A G7, Gmaj7 or Gsus4 is built on (or sits closest to) a G chord, so it shows as G, which still sounds right played along with the recording. That is how most beginner chord charts are written. If you can hear that it is a G7, tap the chord and type G7 to correct it.
On clear recordings where guitar, piano or another chord instrument is easy to hear, most chords come out right. Busy full-band mixes, heavy distortion, loud vocals over quiet chords, and songs built on 7ths or jazz chords are harder. Every chord carries a High, Medium or Low confidence rating, so you know which ones to check by ear, and any chord can be corrected with a tap.
Yes. Tap any chord in the timeline to hear it, jump to that moment in the song, and change it: pick one of the suggested alternatives, choose a different root and major or minor, or type any chord name such as G7 or Cadd9. Your corrections are used when you copy the chords or open them in the Chord Progression Player.
The Song Chord Finder names the chords you hear, at the pitch they sound. If the guitarist uses a capo — say capo 2 with G shapes — the song sounds in A, so it shows A. Turn on capo mode and set the capo fret, and the chords switch to the shapes you would play with that capo. The Capo Calculator can suggest the easiest capo position.
The Song Chord Finder listens to a recording and finds every chord in the song over time. The Chord Finder names a single chord from notes you select on a fretboard. The Song Key Finder, also audio-based, finds only the key of the song; the Song Chord Finder shows that key too, alongside the chords.
