Perfect pitch test: do you have perfect pitch?

How to test for perfect pitch

Use headphones or a quiet room, volume up; on an iPhone the silent switch mutes the tones. Tap Start the test. A short hiss plays, then a tone: tap the key of the note you heard. Octaves don't count, any C is a C, and you may play a tone again before you answer. Go with your first thought. Answer within a second or two. People with perfect pitch name a note about that fast; working it out slowly is relative pitch at work. The test doesn't time you, so keep the pace yourself. Don't hum a note you remember and count from it: that is relative pitch, and the test would measure the wrong thing. After twelve tones you hear all of them in a row, see your answer under each note and read the score.

What it tests is perfect pitch, also called absolute pitch: naming a note when no other note comes before it. Relative pitch is the other skill, naming a note from its distance to one you already know. The keys read C to B; if you learned fixed do, Do is C, Re is D and Mi is E. You need the note names for this test. To test perfect pitch without knowing notes, use the tests for non-musicians further down: they work with songs you know.

What your score means

Guessing names about one note in twelve. It gets two or more one go in four, three or more one go in 14, five or more one go in 520, seven or more once in 66,000. So two is luck, and three or four can be on a given day. Five or six rarely is: usually it means one note you carry in memory, a tuning A or a ringtone, that you measure the rest from. Seven or more is past anything guessing does. Research asks for more: Diana Deutsch's test at UC San Diego plays 36 notes over three octaves and counts 85 % or better as perfect pitch; a 2025 training study counted a note as learned once it was named right 90 % of the time. Here 85 % means 11 or 12. Near misses tell you something too: people with perfect pitch mostly miss by a semitone, and they name the white keys faster and more reliably than the black ones (Miyazaki, 1990). Twelve tones is a short sample. Take the test on three different days: that is the 36 notes the research test uses.

Why relative pitch can't carry you through

Each of the twelve notes plays once, in a random order, anywhere from C3 (130.81 Hz) to B5 (987.77 Hz), tuned to A4 = 440 Hz, and each jumps at least a fifth from the one before, so you name the note, not how high it sounds. Every tone has one of four sounds, picked at random, so no note gives itself away by its colour. Before every tone a short hiss clears your ear, and you only see your answers at the end. Many online tests start with three notes (C, D, E) or the seven white keys and tell you right or wrong after each tone. That is good practice, but every answer you are told becomes a reference for the next tone, so the score measures relative pitch as much as absolute.

It's a quick look, not a lab test. Phone speakers colour the sound, and some people with perfect pitch name piano notes far better than plain electronic tones like these, or name only their own instrument's notes, which researchers call timbre-specific absolute pitch. Nobody with perfect pitch hears hertz: they hear the note the way you see a colour, not a wavelength. The numbers for every note are in the note frequency chart.

How rare is perfect pitch?

The number everyone quotes is one person in 10,000. It goes back to Bachem in 1955 and was never measured in a large random sample, so read it as “rare”, not as a count. Among musicians it is much more common: a 2019 review put it at 4 % or more of music students (Carden and Cline). Two things decide most of it, an early start and the language you grew up speaking. Diana Deutsch's team tested conservatory students on 36 notes (Journal of the Acoustical Society of America, 2006), with 85 % correct as the bar:

Mandarin, Cantonese and Vietnamese give a word its meaning by its pitch, and Deutsch reads her results as children who learn such a language early keeping pitch as a label. Genes play a part too: perfect pitch runs in families, and identical twins share it more often than fraternal twins (Theusch and Gitschier, 2011, a small study). Brain scans show a difference too: in musicians with perfect pitch, the planum temporale, a patch of auditory cortex, is more strongly larger on the left than on the right (Schlaug and colleagues, Science, 1995). Their ears are no better than anyone's. An early start and a tone language make it more likely. Neither guarantees it.

Perfect pitch test for non-musicians

The test above needs the note names. Without them, two tests from research work with any song you know from one recording, heard many times in the same version.

1. Sing the start from memory. Without playing anything first, sing the first line and record it on your phone. Then play the recording and listen to both. In Levitin's study (1994), 12 % of 46 students hit the exact pitch on both of their songs; a repeat with 277 people in six labs in Germany and the UK found 4 % (Frieler and colleagues, 2013).
2. Hear when a song is in the wrong key. Have someone play you two versions of a song you know, one shifted a semitone or two (most audio editors change pitch without changing speed), without telling you which is the original. In Schellenberg and Trehub's study (2003), students picked the original TV theme 58 % of the time at one semitone and 70 % at two, where guessing gets 50 %.
3. Remember one tone. Play one note on the tone generator for a minute, then do something else for an hour. Have someone play you twelve tones, about half of them that note and the rest other notes, and say yes or no to each. Guessing gets about six right; ten or more is pitch memory.

Both show pitch memory, and most people have some. It is the raw material of perfect pitch, not the thing itself: perfect pitch puts a name on the note.

How do you know if you have untrained perfect pitch?

The signs people report before they ever take a test: a song they know sounds wrong when it is played in another key, or slightly fast; they start songs from memory in the original key; a doorbell, a microwave beep or the dial tone has a note to them. If that is you, learn the twelve note names on a keyboard, which takes an evening, and take the test above on three days. Naming notes well above chance before anyone trained you is a strong sign.

With an instrument you can test without a screen. On a piano, guitar or violin, someone plays random keys, frets or strings, plays a few other notes in between, and tells you nothing until the end. Name 36 notes that way: 31 or more right is the 85 % the research uses. Naming every note of a chord with no reference is the harder version.

Perfect pitch singing test

The other half of perfect pitch is singing a note on demand with no reference, which some researchers call aural recall. To test it: before you hear any music that day, pick a note, sing it and hold it on the note reader. It shows the note you are singing and how many cents off you are, live, and holds the last steady note when you stop. Do it on five days, a different note each day. Landing on the note you meant every time, with no pitch pipe and no song in your head, is rare. Being close on one note you sing a lot is common: singers often carry the first note of a favourite song.

Can you learn perfect pitch as an adult?

For some adults, partly, as of 2026. In a study at the University of Chicago (Van Hedger, Heald and Nusbaum, PLOS ONE, 2019), six adults trained about 32 hours over eight weeks. Two afterwards named notes as fast and as accurately as people with perfect pitch, and the better of them passed every test the researchers gave. Retested about four months later, both had kept it. The other four improved a little. In 2025 a team led by Yetta Wong at the University of Surrey (Psychonomic Bulletin and Review) trained 12 adult musicians online for eight weeks, a little over 21 hours: on average they could name seven of the twelve notes at 90 % or better at the end, and two named all twelve, fast and accurately. On the test of all twelve notes at the end, they named 32 % correctly in the sound they had trained, up from 14 %, and less in a sound they hadn't trained.

So it can be done, it takes weeks of daily practice, and most learners end with a handful of reliable notes. The studies' training shares a pattern: start with a few notes in one sound, train speed as well as accuracy, add notes as each one holds, then change instruments and octaves. Short daily sessions beat long weekly ones.

Is perfect pitch related to autism?

Perfect pitch is not a form of autism, and most people with it are not autistic. The two do meet more often than chance: perfect pitch is more common among autistic people (Pamela Heaton's studies, from 1998 on), and musicians with perfect pitch score a little higher on a questionnaire of autistic traits, on the parts about imagination and switching attention, while staying well below the clinical range (Dohn and colleagues, 2012, 16 musicians with perfect pitch against 18 without). Estimates of how many autistic people have it run from a few percent to 30 % (the top figure is Oliver Sacks's, 2007). The studies are small and use different tests, so none of those figures holds up.

Perfect pitch vs relative pitch: a relative pitch test

Most great musicians don't have perfect pitch. What they use is relative pitch: hearing how far apart two notes are, so that once one is given, the rest follow. A relative pitch test plays you a reference note, then another, and asks how far apart they are: that is what interval ear training does, starting with the octave, the fifth and the major third and adding one interval at a time, up and down. Relative pitch is what lets you play by ear, harmonise and transpose, and anyone can train it. The musical ear test scores pitch, intervals, melody and rhythm. Perfect pitch has a cost some of its owners mention: a song moved into another key can sound wrong to them, and a baroque ensemble tuned to A = 415 Hz sounds a semitone off. Spotting a wrong note in a familiar tune, which the NIDCD's Distorted Tunes Test asks, is pitch perception, not perfect pitch. Almost everyone can do it, and the tone-deaf test checks it: five-note melodies played twice, where sometimes one note moves.

Famous musicians with perfect pitch

Mozart is the best-known early case, and a well-documented one. The Salzburg court trumpeter Andreas Schachtner wrote in a letter of 1792 that the boy Mozart told him his violin was tuned “half a quarter tone” lower than Mozart's own. Charlie Puth has shown it on camera, naming notes on Jimmy Kimmel Live. Most of the names on lists online were never tested; the claim comes from interviews or from people who worked with them. Did Michael Jackson have perfect pitch? Nobody ever tested him. The claim rests on stories from people who worked with him. Plenty of the best-known musicians have never claimed it.

Then make something of it

Whatever you scored, the twelve tones you heard go into Brumm as a melody, in time inside a club track with a beat and a bass. Hum your own line there and it becomes an instrument. No account, no upload.
