The learner completes two 18-pair higher/lower sets and reports correct responses by 20-, 10- and 5-Hz difference, upward/downward direction, base frequency, confidence and symptoms.
This dossier explains the evidence and its limits. It is not a diagnosis, personal recommendation, assessment, clearance, performance promise or training programme. Actionable teaching appears only when the canonical Power record explicitly authorises it.
Complete bounded explanation
What this power means.
Capability to develop or express pitch discrimination in a declared context without inheriting broader claims.
What the current evidence supports
Pitch discrimination can improve with practice on a defined frequency or harmonic stimulus, while generalisation is limited.
How to observe or measure it without overclaiming
Use a calibrated just-noticeable difference with declared carrier, harmonic structure, level and procedure; keep naming, memory and discrimination separate.
Myth
Perfect ears
Metric
Pitch/frequency difference threshold across trained and unfamiliar stimuli
Boundary
A smaller just-noticeable difference does not confer note naming, memory, musicianship or general hearing acuity.
Negative and limiting findings
Frequency learning can be tightly centred on the trained frequency.
Absolute-pitch naming practice did not improve fine pitch discrimination or relative-pitch judgement.
Claims this evidence cannot support
Hear every frequency perfectly
Develop perfect pitch by discrimination drills
Superior pitch means superior musician
Louder practice trains faster

How to learn this Power now.
The learner completes two 18-pair higher/lower sets and reports correct responses by 20-, 10- and 5-Hz difference, upward/downward direction, base frequency, confidence and symptoms.
Get readyUse only the supplied question ‘is the second tone higher or lower?’; a same/different task would require another fixture and score.
Learn the method9 concrete steps teach the permitted method from start to finish.
See right and wrong6 comparisons show correct or safer execution beside common wrong or riskier choices.
PractiseRun Set A once, wait at least 48 hours, then run Set B once. A later helper-built pack may add one smaller difference only after two fresh base-frequency sets show a coherent neighbouring pattern; keep U/D balance, level and one-play rule unchanged.
Check progressFor each set, report correct out of three upward and correct out of three downward at 20, 10 and 5 Hz; retain each base pair, answer, confidence, level and symptom entry. Compare Set A with new-base Set B without turning any one cell into an audiometric threshold.
Authority boundary: Titan teaches a concrete low-stakes method step by step while keeping evidence and transfer claims bounded. The method is Power-specific; its actionability follows this treatment.
Citation roles are explicit. A source may support existence or trainability while simultaneously limiting transfer, certainty, generalisation or safety.
