Assessment — no feedback
24 trials over your current pitch set, three octaves, current deadline. No corrective feedback and no replay, so working memory can't act as a crutch — this is how the research measures real absolute-pitch gains.
Pitch mastery
Accuracy over your last 10 attempts per pitch. 9/10 in-time unlocks the next level.
Reset
Wipes all progress and starts from Level 1.
How this app follows the research
Long thought impossible after early childhood, absolute pitch has now been trained in adults in several controlled studies. Each mechanic here maps to a finding:
3 → 12 pitches, unlocked at 90%
The Surrey/CUHK protocol grew the pitch set gradually from three to twelve; learners averaged ~7 pitches named at ≥90% accuracy after ~21 hours, and the best reached all 12.
Short tones, three octaves
Tones last 0.8s and are drawn randomly from C3–B5. A wide range forces you to learn pitch class (chroma) — what makes a note a "C" — rather than pitch height.
A response deadline that tightens
Genuine AP is fast as well as accurate. Training enforced a per-trial time window that shrank with level; top trainees answered correctly in ~2s.
Trial-by-trial corrective feedback
During training every answer is corrected immediately and the true note is replayed. Feedback is removed only in the assessment, exactly as in the studies.
Adaptive repetition of weak pitches
The program oversamples pitches you've recently missed, mirroring the re-introduction of difficult tones in the published protocol.
Short daily sessions
Participants trained ~25 hours spread over 8 weeks. Distributed practice matters — the streak counter is here to nudge consistency, and UChicago follow-ups showed gains persisting months later.
