Pitch Perception Test
Two notes play, and you say which one is higher. This free tone-deaf test starts with an easy gap and narrows it each time you are right, until it finds the smallest pitch difference you can reliably hear. It reports that gap and what it means for your ear. Turn your sound on. Nothing is uploaded and there is no sign-up.
Find out whether you are tone deaf and how fine your pitch perception is. Two tones play in turn, and you choose which is higher. Each correct answer shrinks the gap between them, closing in on the smallest difference you can tell apart, measured in hertz. True tone deafness, or amusia, is rare, and most people who worry about it can actually hear pitch well. This test gives you a clear number rather than a guess, right in your browser.

How to use it
- 1
Turn your sound on
The test is all tones, so you need audio. A quiet room or headphones makes the close calls easier.
- 2
Higher or lower?
Two notes play one after the other. Choose whether the second is higher or lower than the first. Replay them if you need to.
- 3
Close in on your limit
Each correct answer narrows the gap. When you can no longer tell them apart, the test reports the smallest difference you could hear.

Frequently asked questions
- What does it mean to be tone deaf?
- True tone deafness, called amusia, means real difficulty telling musical pitches apart, and it affects only a small share of people. Many who call themselves tone deaf actually hear pitch fine and simply have not trained their singing. This test measures your pitch discrimination directly.
- What is a good pitch difference to detect?
- People with good pitch perception can often tell notes apart when they differ by only a few hertz near the middle of the range. Reliably catching gaps under about 10 to 20 hertz is a strong result. Only struggling with large, obvious gaps would point to real difficulty.
- Do I need headphones?
- They help, especially for the close calls near your limit, because they cut out room noise and play the tones cleanly. Decent speakers work too, as long as the volume is comfortable and steady.
- Why does the gap keep shrinking?
- Starting easy and narrowing after each correct answer lets the test home in on your actual threshold rather than a single lucky guess. The point where you can no longer tell the notes apart is the number that matters.
