Capstone: Transcribe a Melody by Ear
Everything in the core course points here: hear a tune, find its notes, write it down — the skill that turns theory from something you know into something you have.
Builds on: 3.2 Hearing Intervals2.1 The Major Scale
Why transcribe
Reading about intervals is like reading about swimming. Transcription— listening to music and writing down its notes — is the water. It forces every idea in this course to work at once: you must hear the key, feel the scale degrees, tell a step from a leap, name the leap, and place it all on the staff. Musicians who transcribe regularly stop needing sheet music for anything they can hum; the notes simply arrive. It is the fastest route from theory to fluency, and it costs nothing but attention.
Step 1: find home
Before anything else, find the tonic. Listen to the whole phrase, then sing the note the melody seems to want to rest on — usually where it ends, or the note it keeps returning to. Play it on the piano and check: does the melody sound “finished” on it? In this lab every melody is in C major, so home is always C; in real life, finding it is half the job.
Step 2: the first note as a scale degree
Do not hunt for the first note among twelve. Ask instead: which scale degree is it? Melodies overwhelmingly start on the tonic, the third or the fifth — do, mi or sol. Hum the tonic, then the melody’s first note, and feel whether it sits on home, a little above (mi) or higher (sol). Once you know the degree, the note name follows from the key.
Step 3: up or down, step or leap
From note to note, decide two things in order. First, direction: higher, lower or the same. Second, size: a step (to the neighbouring scale note) or a leap. Steps are the majority of any melody and are easy to follow along the scale. Leaps are where your interval training pays off: a bright wide jump up is probably a fifth (Star Wars); a leap that sounds like the start of a chord is a third; an unusually large one is an octave (Somewhere Over the Rainbow). Match the leap to its reference song, count the semitones, land on the note.
Step 4: check against the chord
Notes on strong beats are usually chord tones — members of the chord underneath. If your transcription puts an F on a beat where the harmony is clearly C major, listen again: it may be an E or a G, or the F may be a passing tone between them. Harmony is a net that catches wrong notes.
Step 5: rhythm last
Get the pitches first, then the rhythm. Tap the beat, count the bar, and fit the notes into it; long notes are usually on strong beats, quick ones in between. The transcription bench below concentrates on pitch — it plays every note at the same length — so that you can practise the hard part in isolation.
Listen to the whole melody once without doing anything. Listen again and sing it back. Only then start entering notes, a few at a time, replaying as often as you need — replays are free, guesses are not. When you check, look at the wrong notes: were they direction mistakes or size mistakes? Each type has its own cure.
Pressing keys until one matches is not transcription; it is searching. Decide the note in your head first, then play it to confirm. If you were wrong, that is information: your inner ear learns from every corrected guess, and from nothing else.
The bench below plays melodies of 5, 8 or 12 notes. Transcribe one of each length without a single mistake, play one back from your own staff without listening again, and then take the skill outside: transcribe the first phrase of a song you know from memory and check it at the piano. Tick the steps in the checklist as you complete them — the checklist is what completes this capstone.
🎼 Lab — The Transcription Bench
The bench plays a short melody in C major; you play back what you heard, note by note, and check. Every entered note appears on the staff.
- Start with 5 notes. Listen twice before you enter anything, and sing it.
- Use ⌫ Undo freely — a transcription is finished when it is right, not when it is fast.
- After a check, compare the two staves: were your misses wrong in direction or in size?
