Drop in a song and get its chords bar by bar, lighting up in time as the music plays. We take the vocals and drums out first, so the chords are read from the instruments alone. Transpose it, set a capo, and download the chord sheet as text or PDF. Free, no account.

A chord finder that listens to the whole mix hears everything at once: the sung melody with its notes that are not in the chord, and every drum hit. StemGrab separates the song first and reads the chords from the bass, guitar, piano and other instruments only, with the vocals and drums set aside.
The tempo and the bars come from the full song, drums included, so the chord grid follows the real beat. The key is the same reading our key finder gives for the same file.
We tested it on nine songs we made ourselves, so we knew every chord, and ran them through the tool exactly as you would (28 September 2026). It named the right chord 134 times out of 140 (96%), counting each bar once, and each half bar in the song with two chords per bar:
| Test song | Chords right |
|---|---|
| Pop, C G Am F, piano and bass | 16 of 16 |
| The same with drums and a melody on top | 16 of 16 |
| Rock in D minor, distorted guitar | 15 of 16 (Dm read as D) |
| Ballad in 3/4, picked guitar | 15 of 16 |
| Two chords per bar, electric piano | 16 of 16 (8 bars) |
| Jazz sevenths (Dm7 G7 Cmaj7 A7), read as Dm G C A | 16 of 16 |
| Strings in F# minor, slow | 11 of 12 |
| Inversions, the bass on the third (C/E) | 16 of 16 |
| A loud lead melody over a quiet piano | 13 of 16 |
Our test melodies were played by a synthesizer, and the separation treats a synthesizer as an instrument, not a voice. So these tests say nothing about how much taking out a real singer helps; they do show where it goes wrong: a loud lead line and distorted guitar. Real recordings are messier than test songs, so treat the result as a good first draft and check it by ear.
Transpose moves every chord up or down a semitone at a time, to fit your voice. Capo keeps the song where it is and shows the shapes you play with the capo on: with capo 2, a song in A shows G shapes. Sharps or flats follow the key, so a song in F shows Bb, not A#.
Want to hear the song itself in another key? The key changer shifts the audio. Just need the tempo? The BPM finder reads it in about two seconds.
Yes. Songs up to 15 minutes are free, 10 songs a day, with no account and no watermark. A ShinobiTools pass raises it to 20 minutes per song for chords, with more songs per day.
Upload the song here. We take out the vocals and drums, read the chords from the instruments and show them bar by bar, in time with the music.
Yes: MP3, WAV, M4A, FLAC, OGG and video files all work. You upload the file itself; links from YouTube or Spotify are not supported.
On nine test songs we made ourselves it named the right chord 134 times out of 140 (96%). It reads major and minor chords; a loud lead melody or distorted guitar trips it up most, and the most common slip is a minor chord shown as major (Dm as D). Real recordings are harder than test songs, so check it by ear before you perform.
No. Sevenths, sus and extended chords come back as their basic major or minor chord: G7 shows as G, Cmaj7 as C.
Yes. Transpose moves every chord a semitone at a time, and the capo setting shows the shapes to play with the capo on.
Yes. Download them as a .txt file, or press Print / save as PDF and choose Save as PDF in your browser.
Yes, both, above the chords. The key is the same reading as our key finder gives.
