Tone Deaf Test

How this pitch test works

You hear two short tones, one after the other, and decide whether the second tone was Higher or Lower than the first. That is the whole task, repeated for 30 pairs. It takes about three minutes. Headphones help, but good speakers in a quiet room also work. It checks pitch only; for timing, try the rhythm test.

1. Press Start pitch test. The sound fades in from silence, so set a comfortable volume during the first pair.
2. Each tone lasts 0.5 seconds, with a 0.4 second pause between them. The squares marked 1 and 2 light up while each tone plays.
3. Answer with the buttons or with the arrow keys (↑ for higher, ↓ for lower). If you were distracted, press Play again to hear the same pair once more.

The first pair differs by 200 cents, which is two semitones and easy for most people. After two correct answers in a row the difference gets smaller; after one wrong answer it gets bigger. This is called a 2-down/1-up staircase. It steps by a factor of 1.5 at the start and by 1.2 once you have changed direction twice, so it quickly finds your level and then fine-tunes it. The difference never goes below 1 cent or above 400 cents.

Each pair starts on a new base pitch somewhere between 400 and 600 Hz, and the change is split evenly around it. You therefore cannot remember one reference note and compare everything to it. Only the change within the pair helps you.

How to read your result

Your score is your pitch discrimination threshold: roughly the smallest change in pitch you can still hear reliably. It is calculated as the geometric mean of the last six points where the staircase turned around (or, if there were not enough turns, the last six pairs). Lower is better.

A cent is one hundredth of a semitone, and a semitone is the step between two neighbouring piano keys. The result card puts your threshold into one of five plain-language bands:

These bands are our own labels to make the number easier to read. They are not clinical cut-offs, and we do not show a "typical" value or a percentile, because we found no published norm measured with exactly this method on everyday headphones.

What affects your score, and how to improve it

• Practice and training. In a study by Micheyl and colleagues (2006), people without musical training started with thresholds about six times larger than classical musicians. After roughly two hours of practice the gap was still about fourfold, but a group that kept practising reached the musicians' level after 4 to 8 hours. Pitch hearing is trainable.
• Attention. One lapse can push the staircase up. Take the test when you are rested, and guess when unsure: the staircase corrects itself.
• Listening conditions. Background noise, a fan or a laptop speaker that rattles all make small changes harder to hear. Hearing the very highest pitches is a separate matter, which the hearing age test checks.
• Familiarity. A second run is often better simply because you know what to listen for. Your best score and history stay in this browser.

Tone deaf vs perfect pitch: which one does this test measure?

It is not a perfect pitch test. Perfect pitch, or absolute pitch, is the rare ability to name a note without hearing any reference note (Takeuchi & Hulse, 1993). This test measures relative pitch: whether you hear a change between two tones. Most good musicians have excellent relative pitch without absolute pitch, and the roving base pitch here is designed so that absolute pitch gives no advantage. What it does measure, fine pitch discrimination, is the skill that the real form of tone deafness affects, as the next section explains.

What "tone deaf" really means

Many people call themselves tone deaf because they sing out of tune. Singing, however, also depends on voice control and practice. If you want to see what your voice can do, the vocal range test finds your lowest and highest note. The real condition, congenital amusia, was described by Isabelle Peretz and colleagues (2002) as a disorder of fine-grained pitch discrimination: people with amusia struggle to notice pitch changes that others hear easily, and often cannot tell when a melody is out of tune. A large study by Peretz and Vuvan (2017) with about 20,000 participants estimated that around 1.5% of people have it, lower than the older estimate of about 4% (Kalmus & Fry, 1980).

Researchers diagnose amusia with longer, validated tools such as the Montreal Battery of Evaluation of Amusia (Peretz, Champod & Hyde, 2003), not with a three-minute online check. A high threshold here is a reason to repeat the test in better conditions, not a diagnosis. If pitch changes stay hard to hear across several runs, or you notice other changes in your hearing, an audiologist can check your hearing, and a music teacher can tell you how your pitch perception compares in practice.
