How to Find the Chords of a Song
Stop scrolling for chord charts. Isolate the bass to hear the root, isolate the piano or guitar to hear the quality — and the progression appears.
To find the chords of a song by ear, work bass-first: find the key, isolate the bass to hear the root of each chord, then isolate the piano or guitar to hear whether each chord is major or minor and how it's voiced. Slow down and loop the fast changes, then confirm by playing the chord along with the track. You don't need theory to start, and with Riffloop you do all of it right on the YouTube video, on your device.
No theory required to start — and isolating parts, slowing down and looping to work out chords are free to get started, on your device.

What Does "Finding the Chords" Actually Mean?
Finding the chords means working out the harmony under a song — the stacked notes the bass, piano or guitar play to support the melody — just by listening. For each chord you want two things: the root (the note it's built on) and the quality (major, minor, a 7th).
This is a different job from picking out the tune note by note — that's the melody, and it's its own skill (see transcribing music by ear). Chords are about what's happening underneath. The good news the lesson sites bury: you don't need theory to start. Lead with the bass for the root, decide bright-or-dark for the quality, and let isolating, slowing and looping make the chords obvious while your ear catches up.
The Bass-First Method: 5 Steps
Most guides hand you a wall of theory and treat the tools as an aside. Flip it: the tools are the method. Find the root from the bass, the quality from the chord instrument, and let slow-and-loop handle the fast changes. Here's the workflow, one change at a time.
- Find the key first. Work out the home note before the chords — the key tells you which chords are likely, so you choose from a short list instead of all twelve.
- Isolate the bass for the root. Solo the bass and find the lowest note under each chord. That root is the single most reliable clue to what the chord is.
- Isolate piano or guitar for the quality. Solo the piano or guitar playing the chords so you can hear major vs minor and the voicing on top of the root.
- Slow down and loop the changes. Drop the speed and A-B loop a fast change so it repeats — the pitch stays correct, so the chords stay in the same key.
- Confirm by playing along. Play your chord against the looped, isolated section. If it locks in and disappears into the track, you've got it; if it clashes, adjust the root or the quality.
Root vs Quality — Two Questions Per Chord
Every chord answers two questions: which note is it built on (the root) and what flavour is it (the quality — major, minor, a 7th). Split them and the hunt gets simple: get the root, then get the colour.
🎸 The root (from the bass)
Isolate the bass and find the lowest note under each chord. That root names the chord most of the time — a chord on G is some kind of G chord. Bass-first is the fastest reliable way in, because the bass is one clean line, not a stack.
🎹 The quality (from piano/guitar)
Isolate the piano or guitar and listen for bright (major) or dark (minor), plus any extra tension (a 7th). The voicing — how the notes are stacked — lives here too. With the root already known, you're only choosing the colour.
Find the Key First
Before you chase a single chord, find the key — the note the song keeps "coming home" to. The key tells you which chords are likely, because most of a song's chords are drawn from that key's scale, so you're choosing from a short related list instead of guessing from twelve.
Finding the home note (and whether the song is major or minor) is its own sub-skill — we cover it in depth in how to find the key of a song. Once you know it, the common chords almost suggest themselves, and your bass-first guesses get faster because you already know which roots to expect.
Telling Major from Minor by Ear
Major chords sound bright, open and settled; minor chords sound darker, sadder or more tense. It's a feel, not a calculation — and it's completely learnable. Once you've got the root, this is the only other call you have to make.
- ☀️ Major — bright, happy, resolved, "at peace"
- 🌙 Minor — darker, sad, tense or moody
- 🆚 Compare — play both on the same root, back to back
- 🔁 Loop the chord — match your major and minor guess against it
The fastest way to train this: play a major chord and then a minor chord on the same root and burn the contrast into your ear. Then, with the chord instrument isolated and the change looped, play your guess — whichever version vanishes into the track is the right one.
Fast Changes and Chords You Just Can't Pin
Some songs cycle chords faster than your ear can name them, or bury the harmony under everything else. The fix is always the same three dials, turned further — slower, tighter loop, harder isolation.
- 🐢 Slower — drop the speed so the changes stop blurring together
- 🔁 Tighter loop — loop just one change, even a single bar
- 🎚️ Isolate harder — solo only the bass, then only the chord part
- 👂 Root first, colour second — name the note before the flavour
This is where isolating a part earns its keep. Be honest about it, though: AI separation quality varies — a clean studio mix separates beautifully, while a busy or live recording is harder, so a dense arrangement may need extra slowing and looping. Work the change out slow and alone, then bring the speed back up.
Capos, 7ths and Voicings
A few things trip people up once the basic progression is down. Here's the honest, no-theory take on each — and why none of them should stop you.
🎸 Capos
A capo changes the shapes a guitarist frets, not the chords you hear. Name the chords that sound — the bass note and the major/minor quality — and ignore the capo. If you want their exact shapes, work the sounding chords out first, then figure the capo separately.
🎹 7ths & voicings
Once a chord's plain major or minor is solid, listen for an extra note adding tension — a 7th sounds bluesy or unresolved. The voicing (how the notes are stacked, which is on top) comes from the isolated piano or guitar. These come easy once the basics are second nature.
Confirm by Playing the Chord Along
The final step is the one that makes the method reliable: play your chord against the track. If it locks in and seems to vanish into the song, you've found it. If it clashes or sits on top, the root or the quality is off — adjust and try again.
Keep the section looped and the chord instrument isolated while you test, so you're comparing against a clean reference. Name each chord in order as it changes (say, G, D, Em, C) and note how many bars each lasts. Most pop and folk songs repeat the same few-chord loop, so once you've nailed one cycle you usually have the whole section.
Build the Habit: 10–15 Minutes a Day
A little and often beats a weekly marathon. Ten to fifteen focused minutes most days builds your chord-hearing faster than one long session, because the common changes only start sounding familiar through frequent reps.
Work bass-first every time — root, then quality — on a song you like, and keep a learning loop going so you chip away at one change per sitting. Within a few weeks you'll work out simple three- or four-chord songs; within a few months, trickier progressions and the odd 7th come reliably. Concrete drill: loop the 4-bar chorus at 60% speed, name each chord's root from the isolated bass, then add major-or-minor, then play it back.
Chords vs the Other Two By-Ear Skills
"Working out a song by ear" is really three skills, and they're easiest learned one at a time. This page owns the harmony — the chords. The melody and the key each have their own dedicated guide.
| Skill | Find the chords (this page) | Transcribe the melody | Find the key |
|---|---|---|---|
| What you're after | The harmony | The tune, note by note | The home note / tonic |
| What you isolate | Bass, then piano/guitar | Vocal or lead line | Whatever resolves home |
| The key clue | Root + major/minor | Single-note intervals | The resting note |
| Guide | You're here | Transcribe by ear | Find the key |
They all run on the same slow-loop-isolate workflow — you just point it at a different part. Learn the chords here, and lean on the sibling guides for the melody and the key.
Do It All on the YouTube Video
Most guides tell you to buy desktop software and re-import your audio. You don't need to. With the Riffloop Chrome extension you isolate the bass, isolate the piano or guitar, slow down and loop the changes right on the YouTube song you're already listening to — nothing downloaded, nothing uploaded, on your device.
That's the whole chord-finding workflow in one place: find the key, isolate the bass for the root, isolate the piano or guitar for the quality, slow it down and loop the change — or upload your own file into the Studio if the song isn't on YouTube. It's all part of the Riffloop practice studio, and a step on the way to learning the whole song by ear.
Frequently Asked Questions
How do I find the chords of a song without knowing music theory?
You can start with zero theory by working bass-first: isolate the bass, find the lowest note under each chord, and play that note as a chord — most of the time the root alone gets you close. Then listen for major (bright) or minor (darker). You're matching sounds, not reading symbols. A little theory speeds things up later, but it's not a prerequisite.
What is the bass-first method for finding chords?
Bass-first means you find each chord's root by listening to the bass instead of trying to untangle the whole chord at once. Isolate the bass so it plays alone, find the lowest note under each change, and that root tells you most of the chord. Then you only have to decide the quality — major or minor — on top. It's the fastest reliable way to work out a progression by ear.
How do I tell if a chord is major or minor by ear?
Major chords sound bright, open and resolved; minor chords sound darker, sadder or more tense. It's a feel you can learn — play a major and a minor chord on the same root back to back and the contrast becomes obvious. Isolate the piano or guitar, loop the chord, and compare your major and minor guesses against it until one matches.
How do I work out fast chord changes by ear?
Slow the section down and A-B loop the change so it repeats. At a lower speed the chords stop blurring together and you can hear each one land, and because the pitch is preserved the chords stay in the same key. Loop one change at a time, name it, then move the loop to the next one.
How does the key relate to the chords of a song?
The key tells you which chords are likely, because most of a song's chords come from that key's scale. Find the key first and you're choosing each chord from a short, related list instead of guessing from all twelve — which makes the whole hunt faster. Finding the key is its own skill; see our guide on finding the key of a song.
What if the song uses a capo?
A capo changes the shapes a guitarist plays, not the chords you actually hear. If you're finding chords by ear, just name the chords that sound — the bass note and the major/minor quality — and ignore how the original player fretted them. If you want to match their exact shapes, work out the sounding chords first, then figure the capo position separately.
Can I find the chords of a song from a YouTube video?
Yes — with the Riffloop Chrome extension you isolate the bass, isolate the piano or guitar, slow down and loop the changes right on the YouTube video, with nothing downloaded or uploaded. That's the whole chord-finding workflow on the song you're already listening to, on your device.
How accurate is finding chords this way?
The bass-first method is reliable for the common chords in most songs, and your accuracy climbs with reps. Isolating a part with AI separation helps a lot, though the quality varies — a clean studio mix separates better than a busy or live recording, so a dense arrangement may need more slowing and looping. Always confirm by playing the chord against the track.
What's the best tool to hear a song's chords clearly?
Isolating the instrument playing the chords is the biggest help — solo the piano or guitar and the harmony stops fighting the rest of the mix. Pair that with slowing the section down and looping it, and the root and quality of each chord become much easier to hear. Riffloop does all three on the same YouTube song, on your device.
Do I need the bass to find chords, or can I use the piano or guitar?
Use both — they answer different questions. The bass gives you the root (the note the chord is built on), which is the fastest way to identify the chord. The piano or guitar gives you the quality and voicing (major, minor, a 7th, how the notes are stacked). Find the root from the bass first, then add the colour from the chord instrument.
How do I hear a 7th or extended chord by ear?
Start with the basic major or minor chord from the root, then listen for an extra note adding tension or colour on top — a 7th sounds bluesy or unresolved, leaning you toward the next chord. Isolate the chord instrument, loop it, and play your plain chord, then add the 7th and hear which version matches. Extended chords come easier once plain major and minor are second nature.
Should I slow a song down to find its chords?
Yes — slowing it down is one of the most effective moves for hearing chords, as long as the tool keeps the pitch correct (time-stretching, not the old tape effect). It gives your ear time to catch each chord without changing what the chords are or the key they're in. See our guide on slowing songs down without changing pitch.
How do I write out a chord progression once I've found it?
Loop one section, name each chord in order as it changes (for example G, D, Em, C), and note how many beats or bars each one lasts. Work bar by bar so you're never holding more than one change in your head. Most pop and folk songs repeat the same few-chord loop, so once you have one cycle you often have the whole section.
What if I can find the chords but not the melody?
Chords and melody are different skills — finding chords is about the harmony underneath, while picking out the tune note by note is transcribing the melody. They use the same slow-loop-isolate workflow, but you isolate different parts. If it's the melody you're after, see our guide on transcribing music by ear.
How long does it take to get good at finding chords by ear?
Most people can work out simple three- or four-chord songs within a few weeks of short daily practice, and get reliable at trickier progressions over a few months. It's gradual — each song is faster than the last as common changes start to sound familiar. Ten to fifteen focused minutes a day beats one long weekly session.
Is Riffloop free for finding the chords of a song?
Yes — isolating parts, slowing down and looping to work out chords are free to get started, on your device. Higher daily usage limits and exporting tracks you upload yourself come with Pro ($5.95/mo, $39/yr, or $99 lifetime). The whole chord-finding workflow on a YouTube link is free to use.
