What this test can and cannot tell you
This is a screen, not a diagnosis. Formal absolute-pitch studies use many trials, multiple timbres, response-time measurement, and controls for recent music exposure - a browser test with sine tones can approximate the task but not the rigor. Two honest caveats: the first note you hear can become a reference for a relative-pitch ear, inflating scores; and sine tones are actually harder to name than piano notes for many absolute-pitch possessors, deflating them.
What the test reliably shows is which mechanism your ear uses. Instant, effortless naming across all twelve notes points to absolute pitch. Scores that build from an anchor note point to pitch memory plus interval calculation - which is relative pitch, the trainable skill that powers transcription, tuning, and improvisation. The full story, including why the childhood window matters, is in our perfect pitch vs relative pitch guide.
