Can you name a note without hearing a reference first? This free perfect pitch test plays random notes in random octaves, with a burst of masking noise before each one so you cannot compare it with the last note. Name each note on the wheel. If you name 90% or more exactly, across different sounds, your result is consistent with absolute pitch. Guessing gives about 8%.
Perfect Pitch Test
Hear a note, name it. No reference note.

Press Start: you hear a short noise, then a note. Name it on the wheel. Headphones and a quiet room help. If you are not sure, guess.
Your result
Accuracy by note
Most common mix-ups
By sound and register
Sing a named note without hearing any reference. Any octave counts. The test shows how far you land from the note in cents: a measure of long-term pitch memory, which many people have even without perfect pitch.
Press Start and allow the microphone. Your pitch is hidden while you sing, so the test stays fair. Nothing is recorded or uploaded.

What Does Perfect Pitch Mean?
Perfect pitch, also called absolute pitch, is the ability to name a musical note, or to sing one, without any reference note. Someone with absolute pitch hears a car horn and knows it is roughly an F, or sings an A without a tuning fork. Most musicians instead have relative pitch: they recognise the distance between notes, so they can name a note only after hearing a known one.
Absolute pitch is rare. The figure usually quoted for the general Western population is about 1 in 10,000, though it is far more common in musicians who started lessons before about age 6 and in native speakers of tone languages such as Mandarin or Vietnamese. It is a memory for pitch categories, not better hearing: people with absolute pitch do not hear tiny tuning differences better than other trained musicians.
How the Perfect Pitch Test Works
- Choose 10, 20 or 36 notes and a sound: piano, mixed sounds (piano, organ, strings, clarinet-like, plucked string and pure tone) or pure tones only.
- Press Start test. You hear about 1.5 seconds of noise with scattered random tones, then the note.
- Tap the note on the wheel: C at the top, then clockwise through C♯, D and so on to B. Keyboard users can press C D E F G A B, with Shift for sharps, and R to replay.
- After each answer the wheel shows the right note in green and your choice in red (you can turn this off under More options).
- At the end you get your score, a note-by-note grid, your most common mix-ups and your results by sound and register.
The test is built to stop the usual tricks. Every one of the 12 notes appears equally often (in the 20-note test some notes appear twice), the order is shuffled, the same note never comes twice in a row, and neighbouring notes are always more than two semitones apart. The octave is random within three octaves (C3–B5) or five (C2–B6). The masking sound wipes out your memory of the previous note, so relative pitch does not help. All notes use standard tuning, A4 = 440 Hz.
Fair test tip: use headphones, keep all instruments and tuners out of reach, do not hum a reference song, and answer quickly. If you are not sure, guess: the result corrects for guessing.
How to Read Your Result
| Exact score | What it suggests |
|---|---|
| 90–100% | Consistent with absolute pitch, especially with mixed sounds and a fast answer time. |
| 70–89% | Strong note memory. Many people with absolute pitch land here, often with semitone errors or weaker pure-tone scores. |
| 30–69% | Partial pitch memory: clearly better than chance. Common in musicians who know one reference note well, such as their instrument’s open string. |
| Below 30% | The typical result. Chance is 8.3% exact and 25% within a semitone, and most people, including most trained musicians, score here. |
- Exact vs within a semitone: people with absolute pitch most often miss by one semitone (calling C♯ a C). A high within-a-semitone score with a lower exact score is a known pattern.
- Chance of your score by guessing: the result shows how likely it is to get your number of exact answers by pure guessing (a binomial calculation). A tiny probability means your note memory is real, even if it is not perfect.
- By sound: many people with absolute pitch are best on piano and worst on pure tones, which have no timbre clues. Scoring well on mixed sounds is stronger evidence.
- Mix-ups: if most near misses go the same way, your inner reference may sit slightly sharp or flat. A cent is a hundredth of a semitone.
- Answer time: people with absolute pitch usually name notes almost instantly; slow, worked-out answers suggest relative pitch or a remembered reference.
Perfect Pitch vs Relative Pitch
| Absolute (perfect) pitch | Relative pitch | |
|---|---|---|
| What it is | Naming or singing a note with no reference | Hearing the distance (interval) between notes |
| How common | Rare (about 1 in 10,000 people) | Everyone has some; musicians train it |
| Can adults learn it? | Only partly, with a lot of training | Yes, steadily, with practice |
| Useful for | Naming notes and keys instantly | Singing in tune, playing by ear, harmony, transposing |
For making music, relative pitch matters far more, and it can be trained at any age. Start with the ear training guide, which explains a practice order from single notes to intervals and chords.
Sing a Note: Test Your Pitch Memory
The second tab tests the other side of absolute pitch: producing a note. You see a note name, such as E, and sing it in any octave without hearing anything first. The test hides your pitch while you sing, then shows how many cents you were off. Guessing lands about 300 cents (3 semitones) away on average; within 50 cents counts as the right note.
Research on this “latent” pitch memory found that many people without absolute pitch sing familiar songs close to their original key, so do not be surprised if you land nearer than chance. The singing part uses your microphone with the same pitch engine as our pitch detector; the sound is analysed in your browser and never recorded.
Can You Learn Perfect Pitch?
Absolute pitch usually develops in early childhood, which is why it is linked to early music lessons. Adults can improve their note-naming with regular training, and a few studies report adults reaching high scores after weeks of practice, but full absolute pitch across all sounds and octaves is uncommon. A practical approach is to learn one or two reference notes very well, for example A4 or your lowest comfortable note, and build relative pitch from there. How we hear pitch at all is explained in the science of pitch perception.
Frequently Asked Questions
Is this a perfect pitch detector?
It detects whether you have perfect pitch. If you want a tool that detects the pitch of a sound, use the pitch detector linked above, or see note frequencies in the musical note frequency chart.
Can an online test prove I have absolute pitch?
No online test is proof, but a high exact score on 36 notes with mixed sounds and masking noise is strong evidence. Retake it on another day: absolute pitch gives consistent results.
Why do I keep missing by one semitone?
It is the most common error, even for people with absolute pitch. Pure tones and very high or low notes make it more likely. Check the mix-up list to see whether your errors lean sharp or flat.
I play piano. Is that an advantage?
Pianists often score better on piano sounds than on other timbres. That is why the mixed-sounds option exists: absolute pitch should not depend on the instrument.
Is it free? Is anything recorded?
It is free, needs no account and runs on phones and computers. The listening test needs no microphone. Your best score is saved only in your browser.
