Hear a single note with no reference and name it. How many of twelve can you get?
Perfect pitch and relative pitch are different skills
Perfect (absolute) pitch is knowing a note is F# from the sound alone. Relative pitch is knowing it is F# because you were given a C a moment ago and heard the interval. Most working musicians rely entirely on relative pitch; absolute pitch is rare โ roughly 1 in 10,000 in the general population. This test gives no reference and spaces the questions out precisely to stop you using the previous note as an anchor.
| 12 / 12 | Perfect pitch. Genuinely rare |
|---|---|
| 9โ11 | Close to it โ usually early musical training |
| 6โ8 | Good ear. Often one or two anchor notes (C, A) are memorised |
| 3โ5 | Average. Better than the 1-in-12 you would get by guessing |
| 0โ2 | No absolute pitch. Where most people land |
Why adults rarely acquire it
Absolute pitch almost always develops in people who started music before about age six. After that window, training helps very little โ it appears to have a critical period. Countries where children commonly start piano early (Japan, Korea) report noticeably higher rates than Western countries, which is the usual evidence cited. What adults can acquire is a memory for one note โ many people can produce A440 on demand โ and that alone is useful.
A low score does not mean you are tone-deaf
Tone-deafness (amusia) is difficulty hearing the difference between pitches or matching them with your voice. Not having perfect pitch is simply not having labels for notes you hear perfectly well. Most singers do not have perfect pitch. It even has costs: people with absolute pitch often find transposed songs and slightly off-tuned instruments genuinely uncomfortable.
Getting a fair reading
Different speakers and earphones colour the harmonics, so a note can feel slightly different across devices. Keep the volume moderate, do not listen to other music between questions, and try to answer before using the replay โ that habit gets closest to your real ability.
How to take it
- Sound on, press START. The first note plays straight away.
- Each note is a pure sine tone with no harmonics, lasting about 1.3 seconds. The keys stay locked for the first second; then a "?" appears and all twelve keys unlock.
- Tap one of C, C#, D, D#, E, F, F#, G, G#, A, A#, B โ the black keys are drawn darker. If unsure, you may use Replay once.
- You get โญ Correct or โ It was X immediately, with the right key lit in lime. The next question follows 1.4 seconds later.
- After twelve, you see how many you named, a grade and your personal best. With at least one correct you can enter a nickname for the leaderboard.
How questions are generated
The twelve notes do not each appear once โ every question draws at random from all twelve, avoiding only an immediate repeat. The octave is also drawn per question from octaves 3, 4 and 5, so the range runs from the lowest C (about 131 Hz) to the highest B (about 988 Hz). Only the note name is checked: hear an A4, tap A, and you are right whether or not you knew the octave. Pitches are equal-tempered from A4 = 440 Hz.
Mixing octaves does two things. Someone with absolute pitch hears the same note name across octaves, so they lose nothing; someone counting intervals from the previous note now has an octave jump to untangle as well. The 1.4-second gap after revealing the answer serves the same purpose.
Scoring and the leaderboard
Your score is the number named correctly out of twelve. Guessing blind gives a 1-in-12 chance per question, so about one correct answer is what pure chance produces. Your personal best is stored on the device; the global Top 10 on the title screen ranks by correct answers. A nickname of up to 12 characters is all that is needed โ no account.
Frequently asked questions
Why a beep instead of a piano?
Instrument sounds carry harmonics that let you guess a pitch from timbre. A sine tone strips that away and leaves only the pitch itself. The trade-off is that very low or high sine tones can seem louder or quieter depending on your earphones, so keep the volume moderate.
C# or Db โ which key?
The keys are labelled with sharps only. C# is Db, D# is Eb, F# is Gb, G# is Ab and A# is Bb, so if you think in flats, tap the sharp of the note a semitone below.
How many replays do I get?
One per question. Once used, the button goes dark for that question, and you cannot replay after answering.
I scored 0 and cannot submit
The nickname box only opens for runs with at least one correct answer. Play again and post a score.
Can I use the revealed answer as a reference for the next note?
Nothing stops you, but that is relative pitch โ a perfect twelve done that way is not evidence of absolute pitch. With the octave changing every question it is not easy either.
