Perfect Pitch Test

Hear a note, name it. No reference notes and no hints. Find out if you have absolute pitch, or use the note player to hear any note on the piano.

You’ll hear a random note. Name it on the keyboard, with no reference note. Between notes, a short burst of random tones erases your memory of the last one.

How the perfect pitch test works

  1. Choose your settings. 24 notes give a reliable score. One octave uses notes from middle C up. Five octaves spreads notes from C2 to B6 and is harder. Pure tone removes the piano’s sound color, which is the strictest test.
  2. Listen and click the note you heard on the keyboard, or use your computer keyboard (A = C, W = C♯, S = D, E = D♯, D = E, F = F, T = F♯, G = G, Y = G♯, H = A, U = A♯, J = B). You can replay the note before answering.
  3. See the answer instantly. The correct key turns green, and your answer red if it was wrong.
  4. Between notes, you hear a short burst of random tones. This “pitch eraser” stops you from working out each note from the previous one. That would test relative pitch instead.

  1. Your progress and running score.
  2. Feedback: the right answer, and how far off you were in semitones.
  3. The correct note is green and your answer is red. Every note is equally likely, and each appears equally often.
  4. The next note starts automatically after a moment. Press Next note or Enter to go straight on. Before you answer, a Replay note button lets you hear the note again.

What is perfect pitch?

Perfect pitch, or absolute pitch, is the ability to name or sing a musical note without hearing a reference note first. Someone with perfect pitch hears a car horn and knows it’s an F, the way most people see a color and know it’s red.

It’s rare. Estimates suggest fewer than 1 in 1,000 people in North America and Europe have it. It’s far more common among professional musicians who started lessons in early childhood, and among speakers of tonal languages such as Mandarin, Cantonese and Vietnamese, where pitch changes the meaning of words.

Perfect pitch vs. relative pitch

Perfect pitch isn’t a measure of musical talent. Many great composers and performers don’t have it, and it can even be a nuisance: people with absolute pitch can find transposed music or out-of-tune recordings uncomfortable.

Can you learn perfect pitch?

The honest answer: true absolute pitch is very hard to acquire as an adult. Most people who have it started music before about age 6, which points to a critical period in development. Some adults improve their note-naming a lot with daily practice, and a few reach high accuracy, but most don’t reach the near-instant, effortless naming of people who developed it as children.

What you can build at any age is strong pitch memory: anchoring one or two reference notes, like the A of an orchestra tuning or the lowest string of your guitar, and recalling them reliably. Combined with good relative pitch, that gets you most of the practical benefit.

What does a C note sound like?

Press play to hear each C on the piano as a pure tone. Each C is exactly double the frequency of the one below it, one octave higher. The Note player tab above plays any note with a piano sound.

NoteFrequencyWhere you hear itListen
C132.70 HzThe lowest C on a piano, felt as much as heard
C265.41 HzLow C of the cello (open string)
C3130.81 HzLow C of the viola; a typical male speaking pitch
C4261.63 HzMiddle C, in the center of the piano keyboard
C5523.25 HzTenor high C; the C above middle C
C61046.50 HzSoprano high C
C72093.00 HzNear the top of the flute and piccolo range
C84186.01 HzHighest note on a standard 88-key piano

Middle C (C4) = 261.63 Hz in standard concert tuning (A4 = 440 Hz). It sits in the middle of the piano, just left of the two black keys near the keyboard’s center, and is the note between the treble and bass staves in sheet music. On a guitar, it’s the 1st fret of the B string. Very low notes like C1 may be inaudible on phone or laptop speakers.

Tips for a fair result

  • Don’t hum or sing a reference before the test, and don’t look at an instrument. That turns it into a relative pitch test.
  • Answer quickly. People with absolute pitch name notes in about a second. Long deliberation usually means you’re working it out some other way.
  • Take the test twice on different days. Pitch memory varies with tiredness.
  • Check the per-note chart. Many people with partial absolute pitch do best on white keys, or on the note their instrument tunes to.

Frequently asked questions

How accurate is an online perfect pitch test?

Very good at telling whether you have absolute pitch, because naming notes without a reference is exactly what defines it. Your speakers can’t make a note sound like a different note, so equipment doesn’t matter much. Take at least 24 notes for a reliable score. A single lucky or unlucky round of 12 can swing the result by 10–15%.

What score means I have perfect pitch?

Research studies usually classify people who name 85–90% or more of notes correctly (ignoring octave errors) as absolute pitch possessors. Random guessing scores about 8% (1 in 12). Scores in between often reflect partial pitch memory, which is common in experienced musicians.

Why does the test play random tones between notes?

To stop you using relative pitch. If you know the last note was G, you can work out the next one by its interval, which tests your ear for intervals, not absolute pitch. The burst of random tones erases that short-term reference, a technique used in research tests of absolute pitch.

Can perfect pitch be learned as an adult?

Mostly not, in the strict sense. Absolute pitch develops almost only in people who start musical training in early childhood, typically before age 6. Some adults improve a lot with intensive training: a 2019 study found a few adults reached high accuracy after weeks of practice. But most adults improve their pitch memory without reaching true absolute pitch. Relative pitch, by contrast, can be learned by anyone and is more useful for most musicians.

Is the piano or the pure tone harder?

Pure tones are harder for most people, including many with absolute pitch. Absolute pitch is often tied to timbre: people recognize notes fastest on their own instrument, usually piano. A sine tone has no timbre cues, so it’s the strictest test.

What frequency is the C note?

Middle C (C4) is 261.63 Hz in standard tuning, where the A above it is 440 Hz. Every octave doubles the frequency, so C5 is 523.25 Hz and C3 is 130.81 Hz. See the table above for every C on the piano.

Why do I keep confusing notes a semitone apart?

Semitone errors are the most common mistake, even among people with absolute pitch. Notes a semitone apart differ by only about 6% in frequency. Black-key notes (C♯, E♭, F♯, A♭, B♭) are also named less accurately and more slowly than white-key notes by most people, probably because they come up less often in early music lessons.
