How to transcribe music by ear, and where software helps
Six steps for transcribing by ear, a comparison of ear and software on the jobs that matter, and a way to combine them without trusting either blindly.
The short answer
Pick a song you can hear clearly, find the key, write down the bass line, then the melody, then the rhythm, and check each part by playing it against the recording. Slow the audio without changing its pitch so that each note is audible. Software can draft the notes in a minute, which is useful for the first pass, but a draft is only as good as the ear that checks it, so the steps below still apply, as proofreading instead of as a start from nothing.
How do you transcribe a song by ear, step by step?
- Keythe note the song rests on
- Bassthe skeleton of the chords
- Melodypitches first, then rhythm
- Meterwhere the bar lines fall
- Checkplay it along with the recording
- Find the key. Listen for the note the song feels at rest on, often the last note of the melody or the bass at the end of the chorus. Play it on an instrument and decide whether the music around it sounds major or minor. That gives you the key signature to write at the start.
- Write down the bass line. The lowest notes are easier to hear than the inner voices, and together they give the chords in outline. Songscription’s guide to transcribing by ear makes the same point: do the bass first and the progression follows.
- Work out the melody. Sing a phrase, then find its first note on your instrument and follow it note by note. Most melody notes belong to the key or to the chord under them. Spend your time on the ones that do not.
- Find the meter and the rhythm. Tap the beat, count which beats feel stronger, and write the bar lines before the note lengths. If the first bar is wrong, every bar is wrong.
- Check it against the recording. Play what you wrote along with the recording. A wrong note clashes; a note in the wrong place sounds doubled. Fix, then listen again.
Slowing the recording helps at every step. Use a tool that changes the speed without changing the pitch; at half speed, individual notes are much easier to separate. Loop one phrase at a time rather than playing the song through.
What is each approach good at?
The ear is better at meaning; a program is faster at the first draft. They fail in different places, which is why using both works.
| Job | By ear | A program’s first draft |
|---|---|---|
| Time to a first version | Slow: one phrase at a time | Fast: a minute or two for a short piece |
| Pitches in a clear melody | Reliable once you know the key | Mostly right, with some wrong or missing notes |
| Repeated notes on one pitch | Easy to hear | Can merge into one long note |
| Key signature | You decide it | Estimated from the notes; can be a fifth off |
| Bar lines and meter | You count them | Follows a tempo grid; check it |
| Chords | Work them out from the bass | Written as notes, not chord names |
| What the player meant | You can tell a trill from two notes | Writes what it hears |
On twelve guitar recordings from the public GuitarSet dataset, the model behind ScoreStarling’s one-instrument transcription scored an onset F1 of 0.744 on October 2, 2026, where 1.0 is perfect and a note counts when its pitch and start match, and 0.508 when the end of each note also had to match. Our accuracy article explains the numbers and what the sample cannot show.
How do you use both without trusting either blindly?
- Run the recording through a transcription tool to get a first draft. With MP3 to sheet music you upload the file or paste a link.
- Play the draft beside the recording, two bars at a time, on a loop. The voice memo guide explains the three-way listening check.
- Fix the things the table says drafts get wrong first: bar lines, the key, repeated notes.
- Do the harmony yourself from the bass line, since a draft writes notes and not chords.

Why transcribe by ear at all?
Because it trains the ear, and the ear is what checks any transcription, including a program’s. Someone who has transcribed a few songs hears a wrong bar line or a missing repeated note in seconds. If you only want the notes, a draft is the quicker route; if you want to hear how a song is built, do at least one phrase yourself.

Questions and answers
What should I transcribe first as a beginner?
A song with a clear melody, a plain accompaniment and a slow, steady tempo. One voice or one instrument is easier than a dense mix. Songscription’s guide to transcribing by ear suggests songs slightly above your level; a nursery tune or a slow folk song is a fair first step.
Do I need perfect pitch?
No. Transcribing is a method more than a gift: find the key, work out the bass, then the melody, and check each part against a piano or other instrument. Perfect pitch helps with speed, not with the method.
How slow should I play the recording?
Slow enough to hear each note separately. Songscription’s guide suggests half speed as a start. The tool has to slow the audio without changing its pitch, otherwise you are transcribing in the wrong key.
Can software replace transcribing by ear?
It replaces the first pass, not the checking. A program can draft the notes in a minute; hearing the draft against the recording and fixing it is the part that still takes an ear. It also helps to know what the draft tends to get wrong: repeated notes, the key signature, the end of notes and the bar lines.
Does ScoreStarling transcribe a song by itself?
It writes a first draft from a recording: one instrument or voice, solo piano or a band. Every piece starts with a free 30-second preview and a whole piece of up to six minutes uses 10 credits for one instrument or piano (checked October 17, 2026). You then play the score beside the recording and fix what you hear.
