How to transcribe a song by ear?
By Cedrik Razafimanantsoa, Product Designer and iOS developer · Published · Updated
Transcribing a song by ear means finding its notes and chords just by listening, with no sheet music. The method has three steps. First, find the key: sing the note that "sounds like home" (the tonic) and notice whether the piece is major or minor. Next, transcribe the melody note by note, leaning on interval recognition: each leap between two notes can be named and replayed. Finally, work out the chords by listening to the bass (the lowest note) and the chord color (major, minor). Work slowly, in small loops of two to four seconds, and slow the audio down if needed. The core skill here is relative pitch: the faster you recognize intervals, the faster you transcribe. It is training, not a gift.
Find the key
Look for the resting note, the one the piece "settles" on. Sing it, find it on your instrument: that is the tonic. Major or minor is heard in the overall color.
Transcribe the melody
Move note by note. For each leap, ask which interval you hear (second, third, fourth...). This is where interval training pays off directly.
Loop short passages and sing before you play: the voice confirms what the ear understood.
Work out the chords
Isolate the bass, then listen for whether the chord sounds major or minor. The chord progression is often guessed from common functions (tonic, subdominant, dominant).
Frequently asked questions
Do you need absolute pitch to transcribe a song?
No. Relative pitch is enough, and it is what you train by recognizing intervals.
Which style should I start with?
With simple, clear pieces (single-voice melodies, songs with few chords) before dense arrangements.
Does slowing the audio help?
Yes, slowing without changing pitch helps isolate notes. But interval recognition remains the decisive skill.
