Complete bounded explanation
What this power means.
Capability to develop or express pitch control in a declared context without inheriting broader claims.
What the current evidence supports
Pitch control and pitch-category performance can improve for some learners on defined tasks; perfect or universal pitch is not established.
How to observe or measure it without overclaiming
Cents error, stability, correction latency and task-appropriate independent judgement with feedback configuration declared. Acoustic or timing accuracy does not by itself establish artistry, health, transfer or universal talent.
Perfect pitch is a universal musical superpower anyone can unlock

BoundaryCents error, stability, correction latency and task-appropriate independent judgement with feedback configuration declared. Acoustic or timing accuracy does not by itself establish artistry, health, transfer or universal talent.
Negative and limiting findings
- Only a subset reached the adult study criterion, the design lacked a fully comparable active control, and multimodal training did not isolate its pitch component.
- No evidence supports perfect, limitless or universal performance.
Claims this evidence cannot support
- Anyone can gain perfect pitch
- One tuning system defines musical ability
- Pitch accuracy alone proves singing talent
