Perfect Pitch Test
A single note plays with no reference tone — you name its pitch class (and, if you like, its octave) across a set of trials. Tones are tuned in equal temperament with A4 = 440 Hz, and you can switch between four synthesized timbres. At the end you get a percentage score with some population context.
⭐ This is a screening / practice indicator, not a clinical diagnosis of absolute pitch. True absolute pitch is rare — a widely-published typical estimate is roughly 1 in 10,000 in the general population (Profita & Bidder, 1988; figures vary by definition). With 12 choices, blind guessing scores about 8% (and lower — about 3% — if you also include the octave, since that needs both right), so only a consistently high score across no-reference trials suggests AP aptitude. AP is largely acquired early in life, but relative pitch can be trained at any age. Use a moderate volume; nothing is recorded or uploaded.

Keep it moderate — just loud enough to hear the note clearly. Headphones help, but any timbre is fair game on speakers too.

How It Works
Each trial picks a random note and plays it once, with no reference tone first. That is the whole point: people with relative pitch can name an interval between two notes, but naming a single isolated note out of the blue is the hallmark of absolute pitch (AP), sometimes called "perfect pitch". You hear the note, then tap one of the twelve pitch-class buttons (C, C♯, D…); turn on Include octave to also guess the register, which is harder. All notes are synthesized in 12-tone equal temperament with A4 = 440 Hz, so a note's frequency is exactly f = 440 × 2(m−69)/12, where m is the MIDI number. That math is precise; what is not precise is your equipment, the timbre, and your ears — which is why this is a practice indicator, not a measurement.
The four timbres are all built live in the browser from oscillators, with no audio files. Pure sine is a single frequency — the cleanest and, for many people, the hardest to place because it has no harmonics. Piano-like, bright synth, and guitar-like stack harmonics with different amplitudes and decay envelopes; the words "bright", "warm" and so on are conventional, subjective descriptions, not measurements. Real AP is usually timbre-dependent — many possessors are far better on a familiar instrument than on a bare sine — so testing across timbres is more revealing than any single one.
Your score is simply the percentage of trials you named correctly. With twelve choices, pure guessing lands near 8% (1 in 12) for pitch class only, and lower — about 3% (1 in 36) — if you also include the octave, since a trial then counts only when both are right; so anything in that neighbourhood is chance. A consistently high score across several no-reference tests — especially on the sine timbre, and especially if you also nail the octave — points toward AP aptitude. A single lucky run does not.
