Chord Recognition: AI Detects Guitar & Ukulele Chords
Want to play a song you love, but every chord chart online says something different — so which one is right? Picking out the chords yourself by ear is slow, and you're never quite sure you got them right.
That's exactly why we built Chord Recognition. Muse Forge's newest feature, Chord Recognition, uses AI to detect the chords across a whole song from start to finish. Upload a track or paste a link, and in 1 to 2 minutes you get the full chord progression plus guitar and ukulele fingerings that follow along with the music. Know the chord's name but not how to press it? Just match the shapes and change chords with the song.
What is Chord Recognition?
Chord Recognition uses AI to figure out the chords in a song automatically and lay them out as a complete progression. Muse Forge doesn't just give you chord names — it adds a guitar and ukulele fingering diagram for every chord and switches them in real time as the song plays. Finding the chart, working out the chords, and looking up the shapes all happen in one step.
Why use Chord Recognition?
Chord charts online aren't always right. For the same song, different sites can list chords that contradict each other; for a deeper cut or a brand-new release, there may be no chart at all. Working them out by ear takes some music theory and a lot of patience rewinding.
Chord Recognition skips that whole bottleneck: the song itself is the source, and the AI hears the chords straight from the original recording. What you save isn't just time — it's the nagging doubt of "did I even get these right?"
What can you do with Chord Recognition?
Play along with the songs you love
Drop in the song you want to play, get the full chord progression, and play along with the built-in player. For guitar and ukulele beginners, it's the shortest path from hearing a song to playing it.
Guitar and ukulele fingerings, both covered
Every chord comes with both a guitar and a ukulele fingering diagram, switchable by tab. No more opening another site to look up "how do I play a C chord" — it's right there in the result. Just match the shape.
Understand a song's chord structure
With the full progression laid out, you can see at a glance which chords the verse and chorus use and how they loop. For anyone learning to arrange or studying how songs are written, it's a great place to start taking them apart.
Before uploading someone else's music, make sure you own or have obtained the legal right to use the audio.
How it works: three steps
Step 1: Upload a song or paste a link
Two ways, your choice: drag a song file onto the Chord Recognition page (or click to browse), or just paste a YouTube link. Files support MP3, WAV, FLAC, OGG, AAC, M4A, OPUS, WebM, up to 100 MB each, with an audio length limit of 20 minutes.
Step 2: Wait for recognition
Once uploaded, the AI analyzes and recognizes the full chord progression — usually 1 to 2 minutes, depending on the length of the audio.
Step 3: Play along as you listen
When it's done, you land on the result page. Hit play and you'll see a "Now / Next" dual-card display — which chord to hold now, and what's coming next, cued in real time with the music. Switch the fingering diagrams between guitar and ukulele, and toggle from the Active view (following the song) to the All view (every shape the song uses, at once).
Below that is a full chord progression chart — click any chord to jump to that point in the song, and silent passages are marked with "—". Expand it with one tap to take in the whole structure.
Supported formats and specs
Is Chord Recognition free?
Free to try. Sign up, upload a song, and recognize its chords straight from the audio. The free plan includes a monthly trial allowance shared with AI Music Generation and Stem Separation — one account, a few tools to split your allowance across however you like.
If you transcribe often or want to run through a whole playlist in one go, you can upgrade later: Starter (NT$79/mo) and Creator (NT$199/mo) offer higher monthly allowances.
One account, and chords are just the start
Got your chords — now what? In the same Muse Forge account, you can use Stem Separation to mute the vocals and play along to a clean backing track, or turn the same song into a playable piano version with PopPianoAI — which is completely free. No moving files between tools, no switching accounts. That's what Muse Forge is for: the best tools shouldn't get in the way of creating.
Drop in that song you've always wanted to play but could never find a chart for — and in a few minutes, the whole progression is right in front of you.
