Perfect Pitch Test: Name 24 Notes, See Your Score

A perfect pitch test plays single notes with no reference note and asks you to name each one. Guessing gets about 1 note in 12 right (8.3%), while many published absolute pitch studies set the bar at 85% of notes named exactly. The test below plays 24 notes from C3 to B5, each more than an octave from the last, with a burst of noise in between, then scores you against both lines and shows which notes you mix up.

How to take the perfect pitch test

1. Lower the volume. Turn the system volume down before Start. The level begins at 10% and stops at 25%, and you only need to hear each note clearly. Headphones in a quiet room give the fairest round.
2. Pick the round length. Keep 24 notes for a standard round, choose 12 for a quick check or 36 for the length of the classic research tests.
3. Choose the tone. Start with Piano-like. Sine is the harder version and works best as a second round.
4. Keep the noise on. One second of noise between notes makes the previous note harder to use as a reference. Silence is there for comparison.
5. Name each note. Press Start. Each note plays once for 1 s; click its name or type the letter, with Shift plus the letter for a sharp. The octave doesn't count, so C3 and C5 are both just C. Press Not sure when you have no idea.
6. Read the result. The score appears after the last note, with your mix-ups, response time and the reference lines. Stop or Escape ends a round early and shows a partial result.

A 24-note round takes about two minutes at a steady pace. There's no time limit per note, but the tool records how fast you answer, because speed is part of the picture. Replay is left out on purpose: the documented tests play each tone once at a fixed pace, and a second listen turns the task into comparison.

The note order is built to block shortcuts. Every block of 12 plays each note name once, the three octaves get equal shares, and two notes in a row are always at least 13 semitones apart and never a semitone apart as note names. That follows the design of the UCSD test as described by Van Hedger and colleagues, where every interval between successive notes was larger than an octave to minimize relative pitch as a cue. The no-neighbors rule comes from a Brazilian conservatory study by Leite and colleagues, whose sequences never had a one-semitone step between consecutive tones, ignoring the octave.

I'd press Not sure instead of guessing. It scores zero, the same as a wrong answer, but a lucky guess adds points that say nothing about your ear and puts false mix-ups into the summary.

Reading your perfect pitch score

The headline number is exact naming: how many notes you named correctly out of the round. Under it sits a weighted score that gives full credit for an exact name and three quarters of a point for a miss by one semitone. That scoring comes from the large online study by Athos and colleagues, and Van Hedger's team used the same scheme for the UCSF test. It rewards an ear that lands next to the note.

Four reference lines sit under the score. Guessing names 1 note in 12 on average, 8.3%. A binomial test sets the point where a score is better than guessing at p < .01. Athos's team labeled anyone above 24.5 of 36 weighted points on pure tones as AP1, their absolute pitch group, which is a weighted score above 68.1%. The strict line is 85% exact, the cutoff used by Deutsch and colleagues in their conservatory study and later by Leite and Van Hedger.

Compare the weighted score with its own baseline. Random answers hit the right note 1 time in 12 and a neighbor 2 times in 12, so guessing alone earns a weighted score of about 20.8%, not 8.3%. The tool also reports mean distance in semitones around the note circle, a measure Van Hedger's team used where 0 means every note was right and 3 is what random guessing produces.

Semitone misses deserve a second look before you call a round a failure. Students at the Shanghai Conservatory who began training by age 5 averaged 83% exact and 90% with semitone errors allowed, and semitone errors in that study leaned sharp. Athos's data showed pitch errors growing with age and tending to be sharp too. Deutsch's team noted that some semitone errors may come from growing up with different scales and tuning systems. A sharp/flat split that leans sharp fits those patterns.

The mix-up list shows which note names you swap most often, and the per-note grid shows each note's exact count. In the Shanghai sample, white-key notes were named more accurately than black-key notes, so a weaker score on the sharps matches what that study found.

Speed matters as well. Vanzella and Schellenberg describe response latency as a critical marker of absolute pitch, with possessors answering much faster than non-possessors, and Athos's result figures flag every tone not named within 3 seconds. That's why the result counts answers inside 3 s. A high score built on slow, effortful answers points to careful reasoning more than to instant recognition.

Why sine tones are harder

A sine tone is a single frequency with no overtones. A piano note carries a stack of harmonics and a struck attack. Listeners name piano notes more accurately. Across three published comparisons, the gap has a median of 7 percentage points, with a range of 4 to 30 points:

• Athos's 2,213 online participants averaged 1.55 more weighted points out of 36 on piano tones than on pure tones, about 4.3 percentage points.
• In Vanzella and Schellenberg's study, accuracy was 84% for piano tones and 77% for pure tones, with semitone errors counted as correct.
• Lockhead and Byrd found listeners who scored 99% on piano tones dropped to 69% on pure tones when octave errors were not counted, and to 58% when they were, as summarized in Diana Deutsch's review chapter on absolute pitch.

The same chapter reports Miyazaki's 1989 result with seven AP possessors: piano tones were named best, pianolike tones less well and pure tones worst. The Piano-like option in this tool is a synthesized tone built from six harmonics with a fast attack and decay, not a recorded piano, so a score on it isn't the same as a score on a real instrument. I'd take the first round on Piano-like and the second on Sine. If the exact score holds on Sine, timbre isn't carrying it.

How common perfect pitch is

Perfect pitch is rare in the general population, with estimates for North America and Europe at less than 1 in 10,000, according to Deutsch's review. Music students are a different population. Direct tests at conservatories and music schools found these shares; treat them as estimates, since cutoffs and samples differ.

Across the three samples from Brazil, Poland and the US, the median is 7%, with a range of 4–14%. Across the three from Japan, Beijing and Taiwan, the median is 60%, with a range of 30–72%. The US and Beijing figures count only students who began training at 4 or 5, the earliest-starting group Deutsch's team reported, so both medians lean high. The Brazilian figures come from Leite's study, which found 4% at the strict threshold and 18% when a looser one was added. Both Japanese and Polish figures come from Miyazaki's cross-country comparison, which used a stricter 95% cutoff. Deutsch's team framed its Eastman and Beijing comparison as nontone-language versus tone-language speakers.

Age at first training keeps showing up. Among Eastman students, 14% of those who started at 4–5 met the criterion, 6% of those who started at 6–7, and none who started at 8 or later. A survey of more than 600 musicians by Baharloo and colleagues found 40% self-reported AP among those who started by age 4 and 3% among those who started at 9 or later. Self-report runs high, and Deutsch warns that such percentages are likely exaggerated.

Online numbers need the same caution. Athos's web test found 44% of its 2,213 volunteers above the AP1 line, but those volunteers chose to take a pitch test, and Deutsch's review calls the self-selected results problematic to interpret.

Family and genes play a part without settling the question. Baharloo's respondents with AP were four times more likely to report another possessor in the family. In a twin study by Theusch and Gitschier, the concordance rate was 78.6% for 14 identical pairs and 45.2% for 31 fraternal pairs, and the authors concluded that absolute pitch isn't inherited in a simple single-gene pattern.

Perfect pitch vs relative pitch

Absolute pitch is naming a note with no reference. Relative pitch works from the distance between notes. Vanzella and Schellenberg describe it as the skill that lets you recognize a familiar tune played at a new pitch level and catch a performer's wrong note. With relative pitch, one known note is enough to find the rest by interval.

That's the reason this test has no reference note, wide jumps and noise between trials. Each of those removes a foothold for interval thinking. The protection isn't complete. Van Hedger's team noted that their 1 s of noise may not have fully erased the previous note, and this tool uses the same length.

To practice relative pitch instead, play A4 at 440 Hz in the online tone generator as your reference and sing other notes up or down from it by interval. The pitch detector shows which note you sang and how many cents off it lands. The musical note frequency chart lists every note's frequency if you want to see where C3 and B5 sit.

Can adults learn perfect pitch?

A minority of adults in recent training studies reached the accuracy used to define absolute pitch. Older attempts at adult training produced negative or unconvincing results, according to Deutsch's review. The same review describes Brady's 1970 self-training: about 60 hours with practice tapes, ending at 65% exact and 97% with semitone errors allowed.

Three recent studies trained 62 adults in total, and a median of 15% of trainees reached AP-level scores, with a range of 14–33%:

• In Van Hedger's eight-week study, 2 of 6 adults passed the UCSD test at 94.44% and 97.22%, and the best learner kept the skill for at least four months. Both had scored better before training than the third-best participant did after it.
• Wong and colleagues trained 43 adults for 12 to 40 hours; 6 of them (14%) named all 12 pitches at 90% or better.
• In a second study by Wong's group, 2 of 13 adults learned all 12 pitches after 20 hours, with accuracy and response time comparable to natural possessors.

The trainees were volunteers and the criteria differ, so the share isn't a forecast for any one person. I'd treat training as a way to find out whether you're in the minority that responds. The successful learners in Van Hedger's study already scored well before training, so a first score clearly above the guessing line is the better reason to spend the hours.

Tone deafness and the NIH tunes test

An NIH page sits among the top results for this search, and it measures something else. The NIDCD Distorted Tunes Test plays familiar melodies and asks you to pick out the ones with wrong notes. It's an online version of a standardized test, and it's for people 16 or older. The NIDCD puts the share of the US population with pitch perception problems at 2 to 5 percent and notes that tone deafness isn't necessarily linked to a hearing disorder.

Each test answers its own question. A guessing-level score here is the normal result for most people and says nothing about tune perception. The Distorted Tunes Test is the one built for that question, and the result on this page is a screening score, not a diagnosis.

Limits of an online perfect pitch test

Your setup shapes the score. Laptop speakers thin out low notes and a noisy room masks quiet ones. If one side of your headphones sounds weaker, run the headphone test first. Keep the level moderate: you need to hear each note clearly, not loudly, and if 10% already sounds loud, turn the system volume down further.

Chance never drops to zero. Guessing lands 8.3% of notes on average, and a short round swings more, which is why the 12-note round needs 5 exact before the result counts as better than guessing. I wouldn't judge from one 12-note round; a 36-note round gives a steadier number. The tones are synthesized in equal temperament with A4 at 440 Hz, the same A4 as Deutsch's test. The research tests also ran at a fixed pace, 4 to 4.25 s between note onsets, while this one waits for your answer.

My verdict: treat a score at or above 85% exact on both tones as a strong sign of absolute pitch, and a score between the guessing line and the AP lines as a sign of some pitch memory or relative-pitch help. A browser round is a screen. A lab test with fixed timing and controlled sound is the way to confirm it.

Perfect pitch test FAQ

How do I know if I have perfect pitch?

Name single notes with no reference note and no chance to compare them with the previous one. Many studies use 85% named exactly as the cutoff, so 21 of 24 or 31 of 36 in this test meets that line. A result that holds across several rounds and on the sine tone is more convincing than one good round.

Can I check for perfect pitch without knowing note names?

Not with this test, because it asks you to name each note. Pitch memory without names is common, though. Schellenberg and Trehub's 2003 study found that unselected college students picked the original pitch of familiar TV soundtracks over copies shifted by one or two semitones, while listeners given unfamiliar recordings could not. That's pitch memory, not the note naming that defines perfect pitch.

What percentage of people have perfect pitch?

Estimates for the general population in North America and Europe are below 1 in 10,000. Among music students the share is much higher: a median of 7% across three samples from Brazil, Poland and the US, and 60% across three from Japan, Beijing and Taiwan. The US and Beijing figures cover students who began training at 4 or 5, and all of these are estimates from different tests and cutoffs.

What is a good score on a perfect pitch test?

A score at or above 85% exact meets the strict research line. A weighted score above 68.1%, with three quarters of a point for semitone misses, meets the line Athos and colleagues used for pure tones. Guessing averages 8.3% exact, and on 24 notes, 7 exact is the point where a score beats guessing at p < .01.

Do octave errors count in a perfect pitch test?

Not in this test. You name the note, not the octave, so a C3 answered as C counts as exact. Van Hedger's team scored errors the same way, around the 12-note circle where C3 and C5 are the same note.

Can you learn perfect pitch as an adult?

Some adults can. Across three recent training studies with 62 adults, a median of 15% reached AP-level accuracy by each study's own criterion after 12 to 40 hours of training or an eight-week program. In Van Hedger's study, the two who succeeded already scored well before training.

Why can't I replay the note?

Research tests play each note once at a fixed pace. A replay gives you time to hum the note and work it out from a tune or a note you remember, which is relative pitch at work. Leaving it out keeps the score closer to what published thresholds measure.
