How many correct answers show that I have perfect pitch?

With all 12 notes and 20 questions, getting 17 or more right (85%) within one or two seconds each suggests you very likely have perfect pitch. Guessing gets 1 in 12 (about 8%) right, so 6 or more out of 20 happens by chance less than 1% of the time. This tool shows the odds of reaching your score by chance.

If I am often a semitone off, is that not perfect pitch?

Many people can get within a semitone: they have a memory for pitch but the boundary between neighbouring notes is fuzzy. Some studies give half credit for semitone errors. This tool reports exact and within-a-semitone accuracy separately and shows on which notes, and whether upwards or downwards, you tend to miss.

Can playing clarinet or saxophone shift my perfect pitch?

If you learned notes from transposing-instrument parts, the note you name can differ from the concert pitch. On a B♭ clarinet or trumpet, concert C is written as D (+2 semitones); on an E♭ alto sax it is A (−3); on an F horn it is G (−5). This tool checks whether your errors line up in one of these directions.

Does choosing 440 Hz or 442 Hz change the result?

Hardly at all: the difference is about 8 cents (8% of a semitone). If you usually play at 442 Hz, choose 442 Hz to test with the pitch you are used to. 415 Hz (baroque pitch) is almost a semitone lower, so someone used to 440 Hz will tend to answer a semitone low.

Why do random notes play before each question?

If you know the previous answer, you can work out the next note from the interval (for example, “a third above the last G”) using relative pitch. The random burst wipes that memory so the test measures your ability to judge one note on its own. You can switch it off when you just want to practise casually.

Can adults learn perfect pitch?

Perfect pitch is most common in people who started musical training before about age six, and it is thought to be hard for adults to acquire fully. Adults can still learn to anchor on a familiar note (such as A) and can definitely improve relative pitch (interval recognition). Try the “Intervals (relative pitch)” tab.

How should I practise recognising chords?

Start with just two: the bright major triad and the dark minor triad. Then add diminished (tense) and augmented (floating), and finally sevenths and sus4. Turn on “Also name the root” to make it a perfect pitch test for chords.

Perfect Pitch Test | Free Absolute Pitch Check: Hear One Note and Name It, With Semitone-Error and Transposing-Instrument (B♭, E♭, F) Bias Detection, A=440/442/415 Hz, Chord Quality and Interval (Relative Pitch) Tests

The Perfect Pitch Test is a free check that plays one piano note and asks you which of the 12 notes (C, C♯, D … or Do, Re, Mi …) it was. Choose all 12 notes or white keys only, a 1-, 3- or 5-octave range, a piano, sine or organ tone, and the reference pitch (A4 = 440 Hz, 442 Hz, 415 Hz and more). Before each question it plays a quick burst of random notes to wipe your memory of the previous answer, so the test cannot be solved with relative pitch. At the end you get your exact accuracy and your accuracy within a semitone, the probability of scoring at least that well by pure guessing (binomial), your median response time, accuracy by note and the distribution of your errors from −5 to +6 semitones, with a verdict such as “likely perfect pitch”, “semitone-off type” or “relative pitch type”. If your errors line up at +2 (B♭), −3 (E♭) or −5 (F) semitones, it tells you that you may be naming notes the way a clarinet, trumpet, saxophone or horn part is written. The chord tab trains major, minor, diminished, augmented, sus4 and seventh chords (optionally with the root), the interval tab trains minor seconds to octaves (ascending, descending or harmonic), and the keyboard tab shows the name and frequency of any key.

About Perfect Pitch Test | Free Absolute Pitch Check: Hear One Note and Name It, With Semitone-Error and Transposing-Instrument (B♭, E♭, F) Bias Detection, A=440/442/415 Hz, Chord Quality and Interval (Relative Pitch) Tests

The Perfect Pitch Test is a free tool that plays a single piano note with no reference and asks you to name it on a keyboard. Before each question it plays a burst of random notes to wipe your memory of the previous one, so you cannot work out the answer with relative pitch. At the end it shows your exact accuracy, your accuracy within a semitone, the probability of scoring that well by guessing, your median response time, accuracy by note and the spread of your errors, with a verdict such as “likely perfect pitch”, “semitone-off type” or “relative pitch type”. If your errors line up with how B♭, E♭ or F instruments are written, it flags a transposing-instrument habit. Chord quality (optionally with the root) and interval (relative pitch) tests are included too.

1In “Single-note test (perfect pitch)”, choose the notes (all 12 or white keys only), the range, the tone, the reference pitch (440 Hz, 442 Hz …) and the number of questions
2Put on headphones, check the volume and press “Start the test”
3Answer the last note that plays after the random burst on the on-screen keyboard (or the A W S E D F T G Y H U J keys on a computer). The octave does not matter
4Check the answer and press “Next question” (Enter). Press the space bar to hear the note again
5When you finish, check your accuracy, semitone errors, odds by chance, response time, accuracy by note and the verdict, then copy the result
6Use “Chord recognition” to train major, minor and other chord qualities (and roots), and “Intervals (relative pitch)” to train the distance between two notes

Great for

Find out whether you really have perfect pitch, perhaps from piano lessons as a child
See on which notes, and in which direction, your “almost right but a semitone off” answers happen
Check whether playing clarinet, trumpet, saxophone or horn has left you hearing notes at written rather than concert pitch
Compare whether an ear trained on 442 Hz in a band or orchestra still scores at 440 Hz
Practise chord and interval recognition before music school entrance exams or choir rehearsals
Play a note-guessing game with children using white keys only and one octave
Track accuracy on black keys and weak notes over time to see whether practice is working

Good to know

Perfect pitch (absolute pitch) is the ability to name the pitch of a note without hearing a reference note first. Judging a note from its distance to a reference is called relative pitch, and that is what most people use.
This test plays a burst of random fast notes before each question to wipe your memory of the previous note. Otherwise you could work out the next note from its interval to the last answer using relative pitch. Keep the memory-wiping burst on for a more accurate measurement.
Research often treats 85–90% or more correct when naming one of 12 notes as having absolute pitch, and some studies give half credit for semitone errors. This tool shows both your exact accuracy and your accuracy within a semitone.
“Odds of scoring this well by chance” is the probability of getting at least your score by guessing at random among 12 notes (7 for white keys only), using the binomial distribution. The smaller it is, the more clearly you are hearing the pitch rather than guessing.
People with perfect pitch usually answer most notes within one or two seconds. Long response times suggest you may be counting up from a reference note (such as A) in your head.
If your errors all go the same way, it may be a reading habit. +2 semitones matches B♭ instruments (clarinet, trumpet, tenor sax), −3 semitones matches E♭ instruments (alto sax) and −5 semitones matches F instruments (horn).
Most pianos are tuned to A4 = 440 Hz, Japanese orchestras and wind bands often use 442 Hz, and baroque period instruments use 415 Hz (about a semitone lower). The difference between 440 and 442 Hz is about 8 cents (8% of a semitone), which normally does not change your answers.
Black keys (sharps and flats) and very high or low notes tend to be harder even for people with perfect pitch. Piano-like tones are easier to identify; pure sine waves with no overtones are harder.

How It WorksHow to Test for Perfect Pitch: How Many Correct Answers Mean You Have It, Semitone Errors and Relative Pitch“When I hear a piano note I feel like I know what it is — is that perfect pitch?” Most online note-guessing quizzes can't tell you, because you can work out each note from the previous one, or score well on a white-keys-only quiz by luck. This guide explains the conditions a real perfect pitch test needs, how many of 20 notes you must name before chance can't explain it (a table calculated with the binomial distribution), the 85–90% threshold used in research, why people end up a semitone off or struggle with black keys, the whole-tone, minor-third and fourth errors that clarinet, saxophone and horn players show, the difference between 440 Hz, 442 Hz and 415 Hz, and what adults can realistically train.
