How to Transcribe Music by Ear (Step by Step)
If you want to know how to transcribe music by ear, the method is short: cut a phrase out of the song, slow it down in the Speed Changer so the pitch stays put, and write down what you hear one layer at a time. Before that, find the key and the tempo so you know which notes and beats to expect. Work bass first, then melody, then the inner parts, and check everything against the recording at full speed. All of it runs in your browser, and your audio never leaves your device.
Transcribing is slow at first and gets faster with every song. The steps below are there to stop you guessing at random.
What you'll need
- The song as an audio file you already have on your device.
- An instrument, or a keyboard app on your phone, for checking pitches.
- Somewhere to write: staff paper, a notation app, a tab sheet, or a plain notebook.
- A media player with a repeat button, for looping short clips.
Step 1: Find the key before you write a note
Knowing the key cuts your options from twelve possible notes down to seven likely ones, and every later decision gets easier.
Drop the song into the Key Finder. It shows a Detected key and a Confidence reading of High, Moderate, or Low. Treat the result as an estimate. It works best on clear, tonal material, and a Low reading means you should check it yourself. How to find the key of a song walks through the tool in more detail.
To check by ear, listen for the tonic. The tonic is the home note of the key, the one the song sounds finished on. Hum the note that feels like "home" at the end of a chorus, find it on your instrument, and see whether it matches the detected key. If the two disagree, the most common cause is a relative-key swap, where the detector picks the major or minor key that shares the same seven notes (C major for A minor, say). Wrong key detected explains how to sort that out. Whether the song is major or minor also changes which seven notes you get, so read up on major vs minor keys if you can't tell them apart yet.
Write the key's seven notes at the top of your page. When you later hear a note that isn't on that list, flag it. Notes from outside the key are common, and they're often the ones that give a tune its character.
Step 2: Pin down the tempo and meter
You need two things here: how fast the beat is, and how the beats are grouped.
Open the BPM Finder and drop the song into the Automatic BPM Analyzer. If the result looks off, use Manual Tap Tempo instead and click Tap Beat along with the music for eight beats or so. There's a full guide to tapping out a song's tempo if you haven't done it before.
Automatic detection sometimes reports half or double the real tempo. If it says 70 and the song feels brisk, the working tempo is probably 140. Trust your foot. Half-time vs double-time covers why this happens.
Next, find the meter. Meter is how many beats make up one bar, and which beat feels strongest. Clap along and count until the pattern repeats: "1-2-3-4" is four beats per bar, "1-2-3" is three. Write the tempo and the meter next to the key.
Step 3: Cut the song into short phrases
Short clips help more than anything else on this list. Two to four bars is a good length to start with, short enough to hold in your head while you write.
There's a practical reason to cut first, too. The Speed Changer has no loop or A-B repeat feature. It plays and exports the whole file you give it, so the clip has to be short before it goes in.
Load the song into the Audio Cutter. Move the Trim Start point and Trim End point sliders around one phrase, press Play Selection to check the edges, then press Cut & Download. Start the clip a beat or two early so you hear the lead-in. Name each file by where it sits in the song, like verse1-bars1-4.wav, so your clips stay in order. For cleaner edit points, see how to cut a sample or loop from a song.
Step 4: Slow the phrase down with a speed changer
Open the Speed Changer and drop in your clip. The Tempo slider runs from 0.50× (Slower) to 2.00× (Faster) in steps of 0.05. You can move it while the clip plays and hear the change straight away.
The pitch stays the same at every setting, and for transcription that matters more than anything else the tool does. Slow a recording the old way, like a tape running slow, and every note drops in pitch until nothing matches your instrument. With a music speed changer that preserves pitch, an A is still an A at half speed, so you can check each note against a keyboard as you go. How to slow down a song without changing pitch explains what's happening under the hood.
Some starting points:
- 0.70× to 0.80× suits most melodies and bass lines.
- 0.50× helps with fast runs and ornaments.
- At the slow end, expect some smearing on drums and quick notes. It's a side effect of stretching audio, and the pitches are usually still clear enough to pick out.
When the speed feels right, choose a format and press Export. WAV is the default; MP3 is also available, and Opus where your browser supports it. Put the exported clip in your media player and set it to repeat.
Step 5: Transcribe music by ear in layers
Don't try to hear everything at once. Take one layer per pass.
Start with the bass. It usually plays the root of each chord, meaning the note the chord is named after. Write down the bass note at the start of each bar and you have the skeleton of the harmony.
The melody comes second. With the bass notes written in, it has something to hang on. Listen for the interval between neighboring notes. An interval is the distance in pitch from one note to the next. Ask of each note: is it higher, lower, or the same as the last one? Is it a step away or a leap?
Leave the inner parts for last. These are the notes between bass and melody, and they tell you the chord quality. Play a major chord on the bass note, then a minor one, and hear which matches. If neither is quite right, try adding a seventh.
If the mix is too dense to hear the bass, the Stem Splitter can help. It separates a song into four stems (vocals, drums, bass, and other), and each stem can be soloed or muted. The first time you use it, an AI model downloads to your device. The separation then runs on your own computer, so it takes a while. The result isn't perfect, and you'll often hear a little of one instrument bleeding into another stem. For picking out a bass line it's usually clear enough, and how to extract a bassline from a song covers that job on its own. If it's the words you're after and not the notes, transcribing lyrics by isolating vocals is the same idea applied to the vocal stem.
Step 6: Sing it, find it, write it down
Sing or hum the note before you reach for your instrument. If you can sing it, you've heard it. If you can't, loop the clip a few more times. Hunting for notes on the instrument without singing first turns into trial and error.
Then work in this order:
- Rhythm first. Mark the beats of the bar across the page and place a tick where each note starts. With the rhythm down, pitch is the only thing left to solve.
- Pitches second. Sing each note, find it on your instrument, and write it above its tick.
Use whatever notation you can read back later. Staff notation holds the most detail. Tab works well for guitar and bass. A chord chart is enough if you only need the harmony. You can also write scale-degree numbers, where 1 is the tonic and 5 is the fifth note of the key, which makes the part easy to move to another key.
Finish one phrase before you cut the next.
Step 7: Check your transcription at full speed
Slow audio hides mistakes in rhythm and feel. Play what you wrote along with the original recording at 1.00×.
Wrong notes will clash against the track. Circle them, go back to the slow clip for that bar, and fix them. Also check that your phrases join up. The last note of one clip and the first note of the next are the easiest places to miscount.
Once the page is right, you'll probably want to play it. How to slow down music to practice an instrument turns the same clips into a practice routine, and there are more guides like this one in the audio how-to guides hub.
Troubleshooting
I can't tell which octave the note is in. This is normal, especially for bass. Get the note name right first. Then play it in two octaves against the recording and pick the one that blends in.
Two different notes both sound right. They may both be in the chord. Sing the line on its own, away from the recording, and see which note you land on. Then check it against the bass note you wrote for that bar.
Every note sounds slightly sharp or flat. The recording may not be tuned to standard pitch (A = 440 Hz), which happens with older records and some live takes. What is concert pitch has the background. The simplest fix is to retune your instrument to the track. If the whole band is tuned a full half step down, the Pitch Changer can shift the clip up one semitone instead; it moves in whole semitones, so it can't correct a smaller offset.
It's too fast even at 0.50×. Cut a shorter clip. One bar, or even two beats, is fine. Solve those few notes and move on.
Frequently asked questions
Is slowing down a recording cheating? No. Slowing a recording down is a standard way to transcribe, and musicians did it with tape and record players long before software existed. You still do the listening and the writing yourself. As your ear improves you'll need less slowing down, and many people find they only use it for the fastest passages.
How long does it take to transcribe a song? It depends on the song and on your experience. A simple melody over a few chords goes much faster than a dense arrangement or a fast solo. Your first transcriptions will feel slow, and that's expected. Each one trains your ear, so the same kind of passage takes noticeably less effort after you've done a few.
Do I need perfect pitch to transcribe music by ear? No. Most people who transcribe use relative pitch, which means hearing how far each note is from the one before it or from the home note of the key. Relative pitch is a skill you can build with practice. Finding the key first and checking notes on an instrument covers the rest.
Can software transcribe music automatically? Automatic transcription tools exist, and they can give a useful rough draft on simple, clean recordings such as a solo piano. They tend to struggle with dense mixes, and the output usually needs checking by ear. Vocal Cut doesn't have an automatic transcription tool. Its tools help you hear the music more clearly so you can write it down yourself.
