Perfect pitch test can you name a note out of nowhere?

How does this perfect pitch test work?

The test plays 12 random notes between C3 and B5, three octaves in the middle of the piano, with a piano-like sound. Before each note you hear a short burst of noise. You pick one of the 12 note names (C, C♯, D and so on up to B), and at the end you get two scores: exact answers, and answers within a semitone.

Only the note name counts, not the octave. If the test plays C3 and you answer C, that is correct. In absolute pitch the question is whether you recognise the pitch class, the "C-ness" of a C, wherever it sits on the keyboard.

Use headphones or decent speakers, in a quiet room, at a comfortable volume. A phone speaker plays the lowest notes of the range thinly, and that makes them harder to judge. The WHO advises keeping device volume at no more than 60 % of maximum, which is plenty for this test.

Why is there noise before each note?

The burst of noise is there to stop you from using relative pitch. Without it, you could hear the first note, guess it, and then work out every later note from the interval to the one before. A good musician with relative pitch would score far above chance that way without having absolute pitch at all.

Noise has no pitch of its own, so it gives you nothing to measure the next note against, and it pushes the previous note out of your immediate attention. Each note then has to be named on its own, which is what absolute pitch means.

The notes are also random, so there is no pattern to learn from one round to the next. If you take the test several times, each round is a fresh draw from the same 36 notes.

What does my perfect pitch test score mean?

Your exact score is the number of notes you named correctly out of 12. With 12 possible answers, pure guessing gives a 1 in 12 chance on every note, so the average guesser gets 1 right. The within-a-semitone score also counts the neighbouring notes, so guessing gets about 3 in 12 of those.

The table shows how often pure guessing reaches a given score. It is the plain binomial probability for 12 tries with a 1 in 12 chance each.

The result labels on this page are our own rule of thumb, not a published cut-off: 0 to 3 exact answers is what most people score, 4 to 8 is better than chance, and 9 to 12 looks like perfect pitch. In research, the bar is set higher and the test is longer: in the Deutsch conservatory study, students heard 36 notes and needed 85 % correct to count as having absolute pitch.

A single round of 12 notes is short. If you scored in the middle band, take it two or three more times and look at the total. A real ability shows up again and again; a lucky round does not.

What is perfect pitch (absolute pitch)?

Perfect pitch, called absolute pitch in research, is the ability to name a note you hear without any reference note. Someone with absolute pitch hears a car horn or a single piano key and can say "that is an F♯" the way most people would name a colour.

It is a skill of memory and naming, not of sharper ears. Two neighbouring piano keys differ by about 6 % in frequency, or 100 cents. Ordinary listeners can tell apart tones far closer than that: above 1,000 Hz the just-noticeable difference is about 0.6 %, roughly 10 cents. So almost everyone can hear that two notes are different. What people with absolute pitch have is a fixed internal label for each of the 12 notes.

The notes in this test run from C3 at about 130.8 Hz to B5 at about 987.8 Hz, tuned to the international standard of A = 440 Hz (ISO 16). Each step up is a ratio of 2^(1/12), so twelve steps double the frequency and land on the same note name an octave higher.

How rare is perfect pitch? The 1 in 10,000 figure

Nobody knows how common perfect pitch is in the general population. The famous "1 in 10,000" figure is an estimate, not the result of a survey. Diana Deutsch, writing in Acoustics Today in 2006, described "an estimated overall prevalence of less than one in ten thousand", citing a 1988 paper by Profita and Bidder; the figure is often traced back further, to a 1955 paper by Bachem, and Wikipedia notes that it "may not be accurate".

Among musicians the picture is very different. A 2019 review by Jane Carden and Tony Cline in Psychology of Music concluded that the assumed extreme rarity of absolute pitch "is not supported by empirical evidence", and that studies indicate at least 4 % among music students. That is 400 times the old estimate.

Musicians are of course not a random sample: they have trained their ears for years, and many began young, which, as the next section shows, matters a great deal. So the honest summary is this: perfect pitch is uncommon, it is clearly more common among musicians than the old figure suggests, and its rate in the whole population has not been measured.

Why do some people have perfect pitch? Early training and tone languages

Two things are strongly linked to perfect pitch: starting music early and speaking a tone language such as Mandarin. In a 2006 study, Deutsch and colleagues tested 88 Mandarin-speaking students at a conservatory in Beijing and 115 students at the Eastman School of Music in the United States who did not speak a tone language. Everyone in the classes was tested, so the results were not skewed by volunteers who thought they had the gift.

The students heard 36 piano notes and needed 85 % correct to pass. The difference between the groups was large, and in both groups the earlier the training began, the more common absolute pitch was.

The percentages are Deutsch's own reading of the paper's figure, given in her 2006 Acoustics Today article. The authors saw the results as evidence for a speech-related critical period: in a tone language, the pitch of a syllable changes its meaning, so children learn early to attach labels to pitch.

A 2009 follow-up at an American conservatory sharpened the point. Among students of East Asian background, those who spoke a tone language very fluently scored much higher, while East Asian students who were not fluent scored like other students who spoke no tone language. Ancestry alone did not explain it, and early training helped independently of language.

Absolute pitch vs relative pitch: what is the difference?

Absolute pitch is naming a note on its own; relative pitch is recognising the distance between notes. With relative pitch you hear two notes and know they are a fifth apart, or you are given a starting note and can find the rest of the tune from it. It is what most musicians rely on, and it can be trained.

The two are not rivals. Dooley and Deutsch (2011) compared 18 musicians with absolute pitch and 18 without, matched for training, on naming intervals: those with absolute pitch were also better at it. For a working musician, good relative pitch is the more useful skill, because transposing, singing in a choir and playing by ear all depend on intervals, not on fixed labels.

How can I test my relative pitch?

A relative pitch test always gives you a reference: it plays one note, then another, and asks for the interval, or it names the first note and asks you to name the second. This test deliberately removes the reference, so it measures absolute pitch only.

You can check your relative pitch with the tools on this site. The note frequency chart plays any piano key, so you can play a C, then the E or G above it, and practise naming the intervals. The tone deaf test measures something more basic: the smallest pitch step, in cents, at which you can still tell whether a second tone is higher or lower than the first.

Pitch discrimination improves with practice. In a 2006 study by Micheyl and colleagues, untrained listeners at first needed pitch differences more than six times larger than classical musicians to tell two tones apart, still about four times larger after 2 hours of practice, and they needed 4 to 8 hours of training to match the musicians.

Can you learn perfect pitch as an adult?

The research described on this page links perfect pitch to childhood: to music lessons that began at 4 to 7 years and to growing up with a tone language. It does not show that adults can acquire it, and it does not settle the question either way. Be wary of courses that promise perfect pitch in a few weeks; the studies here give no basis for such a promise.

What adults can clearly improve is relative pitch and fine pitch discrimination, as the Micheyl study shows, and those skills cover most of what musicians actually need. If you enjoy this test, retake it now and then and keep a record of your scores; it is a fair way to see whether anything changes, without any promise about where it leads.

Perfect pitch test for non-musicians: what to expect

A non-musician can take this test, but it needs one thing first: the names of the 12 notes. The test asks you to name what you hear, so if you do not know which sound is called D and which is called A, you will score at chance level whatever your ears are like.

If you want to try properly, spend a few minutes with the note frequency chart, playing the keys from C to B and listening to each one, then come back. Expect a score near 1; that is what most people get, musicians included. A low score says nothing about your musicality. Absolute pitch is a specific kind of note memory, and many excellent musicians do not have it.

A low score is also not a sign of tone deafness. True tone deafness, congenital amusia, affects about 1.5 % of people according to a study of about 20,000 participants (Peretz and Vuvan, 2017), and most people who sing out of tune hear pitch normally: in a 2007 study, the 10 to 15 % who sang a semitone or more off discriminated pitch as well as good singers. If that is your worry, the tone deaf test is the right place to start.
