Perfect Pitch Test — do you have absolute pitch? (online note test)
Hear 10 notes with no reference and name each one. Three difficulty levels up to five octaves with mixed timbres and masking noise, A4 = 440 or 442 Hz, average semitone error, personal bests and a shareable challenge with the same notes.

Name the note without a reference. A single wrong answer one semitone away is still a very good sign; most people without absolute pitch spread their answers across the whole octave. Headphones help, especially for the low octaves.
About this tool
This perfect pitch test checks whether you can name a musical note with no reference tone. Press Start and you hear ten notes one at a time; pick each one from the keyboard — white keys only or all twelve. Easy keeps to a single octave with a piano-like tone, Normal spreads over three octaves, and Hard covers five octaves with changing timbres and a burst of noise before every note so you cannot work from the previous one. Each answer tells you the note and its frequency, and at the end you get your score and average semitone error. Switch the reference between A4 = 440 Hz and 442 Hz, keep a personal best, and share a link that plays the same notes to a friend. Everything runs in your browser.
Frequently asked questions
What is perfect pitch, and how rare is it?
Perfect or absolute pitch is the ability to name a note, or sing one on request, without hearing a reference. It is commonly estimated at around 1 in 10,000 people in Western populations, but it is far more common among musicians who began lessons in early childhood, and studies of conservatory students have found much higher rates among speakers of tone languages such as Mandarin. Relative pitch — naming notes from their distance to a known note — is a different and very learnable skill.
Can adults learn perfect pitch?
Mostly it develops in early childhood, usually with music training before about age six, which is why it is often described as having a critical period. Adults who practise note naming do get better, especially on their own instrument's sound, and a few recent training studies have reported adults reaching high accuracy, but that remains the exception. For practical musicianship, strong relative pitch matters more — the interval and chord training on this site builds exactly that.
Why does Hard mode play noise before each note?
To stop relative pitch from doing the work. If you know the previous note was G and the next one sounds a major third higher, you can deduce B without absolute pitch at all. A burst of noise between notes, together with large octave jumps and changing timbres, disrupts that short-term comparison — the same idea used in research tests of absolute pitch. Easy and Normal leave it out, so a high score there may partly reflect good relative pitch.
I am often off by one semitone — what does that mean?
It is a good sign. Semitone errors are the most common mistake even among people with absolute pitch, especially for black-key notes, unfamiliar timbres and very high or low octaves; research has also found that many absolute-pitch possessors name white-key notes faster and more accurately. Guessing would scatter your errors across the octave and average about three semitones. The test only scores the note name, so an answer in the wrong octave is never counted as an error.
Should I use A4 = 440 Hz or 442 Hz?
Use whichever you grew up with. 440 Hz is the international standard and what most pianos, apps and recordings use; many orchestras in Japan and continental Europe tune to 442 Hz or slightly higher. The difference is only about 7.9 cents — far less than a semitone — so it will not change which note you hear, but people with very precise absolute pitch sometimes find one setting sounds "in tune" and the other slightly sharp or flat.
