Remember the shape of a short melody after a filled delay, then transpose it
Pitch memory is more widespread than note naming, and some adults can learn the labels—without becoming musically superior. Relational pitch memory tracks whether notes went up, down or stayed similar, separate from naming exact pitches. The learner hears a four-note synthetic sequence once, completes a filled delay, reproduces its contour with arrows, humming or note relations, checks the reference and retests a new starting pitch. Adult absolute-pitch claims remain limited. Contour scoring includes intrusion analysis: a repeated old melody, reversed final interval or preserved rhythm with wrong pitch shape is marked separately from a complete memory failure.

Gather what you need and check the starting conditions
What you need
- Set A, played with one piano/tone sound at 500 ms per note and a 200-ms silent gap: A1 C4–D4–E4–D4 (UUD), A2 E4–D4–D4–F4 (DSU), A3 G4–E4–F4–F4 (DUS), A4 D4–D4–C4–E4 (SDU), A5 A4–C5–B4–D5 (UDU), A6 F4–E4–G4–F4 (DUD), A7 C5–B4–A4–A4 (DDS), A8 E4–G4–G4–F4 (USD). A helper codes files A1–A8 and hides the parenthesised contour key.
- Transposed Set B with the same durations, sound and contour order: B1 F4–G4–A4–G4 (UUD), B2 A4–G4–G4–B4 (DSU), B3 C5–A4–B4–B4 (DUS), B4 G4–G4–F4–A4 (SDU), B5 D4–F4–E4–G4 (UDU), B6 B3–A3–C4–B3 (DUD), B7 F5–E5–D5–D5 (DDS), B8 A3–C4–C4–B3 (USD). Keep B sealed for at least 48 hours.
- A 20-second interference strip numbered 1–20 with symbols ○ △ □ ○ ◇ △ ○ □ △ ◇ ○ □ ○ △ ◇ □ ○ △ □ ○. At one symbol per second, the learner says its position number only when it is ○; the helper or timer maintains the pace. No humming, finger tracing of pitch or note rehearsal occurs.
- Three arrow cards U, D and S; a response sheet with sequence code, three-arrow response, confidence, three keyed transitions, first wrong position, error class and optional exact-note answer kept in a separate column.
Before you start
- Choose relational contour as the main outcome; absolute note naming stays separate.
- Set one comfortable level and fixed playback chain.
- Use the same filled-delay duration and task.
- Do not sing loudly or strain; humming is optional.
3 · The method
Follow these steps in order
- Learn contour symbols
Practise up, down and same arrows on obvious two-note examples.
Why: A shared notation lets non-singers show the relation.
Check: All practice relations are labelled correctly.
- Lock one exposure
Play one coded A sequence once at the fixed level: each note lasts 500 ms and each inter-note silence lasts 200 ms. Cover the player when playback ends and do not loop it.
Why: One exposure defines the memory demand.
Check: Play count is recorded as one.
- Fill the delay
Immediately follow the numbered symbol strip at one symbol per second for 20 seconds, saying only the number of each ○. Do not hum, tap the contour or rehearse note names.
Why: A filled delay reduces immediate echo and standardises retention time.
Check: Delay duration and task are completed.
- Reproduce the relation
Use three arrows, relative note labels, an instrument or gentle humming to show how note 2–4 moved from the previous note.
Why: Contour is the intended memory, not exact frequency.
Check: A complete three-transition response is committed.
- Check transition by transition
Reveal the reference and mark each up/down/same relation correct or wrong; keep absolute-note labels separate.
Why: Specific transition feedback identifies the memory error.
Check: Three relation scores remain visible.
- Use spaced correction
Replay once, wait through the same delay and reproduce again only under the planned feedback trial.
Why: One spaced correction teaches without endless looping.
Check: Correction exposure and result are labelled.
- Transpose the test
At least 48 hours later, use B1–B8 in a newly shuffled code order. Each B item preserves one A contour but starts on other notes; keep timing, sound, delay strip and one-listen rule unchanged.
Why: Transposition tests relational memory rather than one recording.
Check: Starting pitch changes while contour rule stays explicit.
- Classify the contour error
When a response is wrong, mark the first incorrect transition and classify reversal, repeated previous contour, flattened transition or missing response. Keep rhythm or note-name errors in separate columns.
Why: A whole-contour score alone cannot show whether interference from an earlier melody or one transition caused the failure.
Check: Each missed sequence has a first-error position and one pitch-contour category without rewriting the original arrows.
4 · Worked example
See the whole method used once
Scenario
Ana receives coded A1, C4–D4–E4–D4, whose hidden contour is UUD.
Walkthrough
- Ana practises U, D and S on unscored two-note examples and records the comfortable playback setting.
- She hears A1 once, then follows all 20 symbols and says 1, 4, 7, 11, 13, 17 and 20 because those positions contain ○.
- Ana commits UDD with confidence 2/3. The key UUD gives transition scores correct, wrong, correct; first error position 2 is a reversal from U to D.
- For the planned correction only, she replays A1 once, completes the same 20-second strip and now writes UUD; the correction is not substituted for baseline.
- Two days later B1, F4–G4–A4–G4, tests UUD from another starting note with the same one-listen and filled-delay rules.
- If Ana writes the entire previous trial’s contour instead, she marks previous-sequence intrusion; if only a moving interval becomes S, she marks flattening.
Result
Ana retains the relational shape better after spacing and transposition. This does not demonstrate categorical absolute pitch or musical superiority. The added error profile shows whether spaced practice reduced interference rather than only raising whole-sequence scores.
5 · Right and wrong
Compare correct or safer execution with the common wrong version
| Moment | Right / safer | Wrong / riskier | Why it matters |
|---|---|---|---|
| Outcome | Score up/down/same contour separately. | Mix exact note names and contour into one score. | Absolute naming and relational memory are different abilities. |
| Exposure | Use one declared listen before the delay. | Loop until memorised. | Extra exposures reduce the memory demand. |
| Delay | Use the same filled interval. | Rehearse the notes during an empty variable delay. | Rehearsal and time change the task. |
| Reproduction | Use arrows, instrument or gentle humming. | Require accurate singing to count memory. | Vocal control is a separate skill. |
| Transfer | Transpose the contour to a new starting pitch. | Repeat one recording and claim general pitch memory. | Recording memory may not preserve relations elsewhere. |
| Memory error | Mark the first wrong transition and whether an old contour intruded. | Score the whole sequence zero and discard the response shape. | The retained shape shows what was remembered and what interfered. |
6 · Common mistakes
Spot the error and apply the correction
| Mistake | Fix |
|---|---|
| Mix exact note names and contour into one score. | Score up/down/same contour separately. |
| Loop until memorised. | Use one declared listen before the delay. |
| Rehearse the notes during an empty variable delay. | Use the same filled interval. |
| Require accurate singing to count memory. | Use arrows, instrument or gentle humming. |
| Repeat one recording and claim general pitch memory. | Transpose the contour to a new starting pitch. |
| Sequences with the same rhythm are grouped together, allowing rhythm to cue the contour. | Use matched rhythm across balanced contours or vary rhythm independently and report it as a separate feature. |
7 · Practice
Turn the steps into a usable skill
First session
- A helper renders A1–A8 with the stated notes and timing, codes the files and checks each hidden contour against the printed key.
- The learner practises U, D and S on three unscored two-note pairs, then rehearses the interference strip once without any melody.
- In a concealed A1–A4 order, the learner hears each file once, completes all 20 seconds of symbols and commits three arrows plus confidence before the next file.
- After all four, the helper reveals their keys. The learner scores 12 transitions, four whole contours and the first wrong transition/error class for each miss.
- Only a missed item receives one correction exposure followed by the same filled delay; the corrected row stays separate from baseline.
- A5–A8 form the next fresh practice block, while transposed B files remain sealed for the 48-hour transfer check.
Repeat plan
Use A5–A8 at the next weekly practice, then run B1–B8 after at least 48 hours without reopening A. Progress first from four to eight coded items, then vary delay to 30 seconds on newly generated four-note contours; do not change delay and starting pitch in the same comparison.
Progress when
- Contour accuracy improves after the fixed delay.
- Confidence becomes calibrated.
- Relations survive a new starting pitch or novel sequence.
Do not progress when
- Exact pitch and contour scores are merged.
- The learner loops recordings or changes delay.
- Ear, voice or fatigue symptoms appear.
8 · Check the result
Measure what changed
Relational contour retained after the fixed filled delay
How: For each code, score correct U/D/S transitions out of three and whole-contour correct/incorrect after exactly one listen and 20 seconds. Report first-error position plus reversal, previous-sequence intrusion, flattening or omission; compare A and transposed B while keeping exact-note naming in its own column.
Good result: On concealed B files or new four-note contours, more transitions or complete contours are retained under the same delay and exposure rule, without louder playback or increased symptoms; a correction trial is never counted as a fresh baseline.
This does not prove: Separate familiar-pitch memory, isolated-note naming, relational interval judgement, timbre/octave transfer and delayed retention; avoid a single binary label.
Self-check
- Can you demonstrate “Lock one exposure”? Play count is recorded as one.
- Can you demonstrate “Reproduce the relation”? A complete three-transition response is committed.
- Can you demonstrate “Transpose the test”? Starting pitch changes while contour rule stays explicit.
- Can you distinguish forgetting one transition from reproducing the previous trial’s complete contour?
9 · Stop, adapt or get help
Keep the safety boundary practical
Stop and get help
- Stop for ear pain, tinnitus increase, dizziness or vocal strain.
- Stop the pitch task and obtain prompt assessment for an abrupt hearing change, a new marked difference between ears or severe vertigo rather than retesting the melody.
- Seek professional support when pitch or memory change is sudden or affects daily function.
Accessibility and adaptations
- Use arrows, tactile tokens, note names, instrument keys or humming; no single output mode is required.
- Use a nonvisual filled-delay task and audio/tactile response system.
- Keep hearing devices and comfortable vocal range as declared supports.
10 · Evidence and limits

Primary research supports widespread memory for pitch in familiar melodies without equating it with categorical absolute-pitch naming.
Absolute memory for musical pitch: evidence from the production of learned melodies - primary research
Adult-learning research suggests some note-label acquisition while leaving universality, retention and musical value bounded.
Is it impossible to acquire absolute pitch in adulthood?
Limits
- Separate familiar-pitch memory, isolated-note naming, relational interval judgement, timbre/octave transfer and delayed retention; avoid a single binary label.
- Unsupported claim: Anyone can acquire perfect pitch.
- Unsupported claim: Absolute pitch makes a better musician.
- Unsupported claim: Pitch naming improves all hearing.
- Relational contour memory does not establish absolute pitch, exact-Hz recall, musical talent or broad auditory memory.
