Take the Distorted Tunes Test

Welcome to the Distorted Tunes Test (DTT). Take the test in a quiet room free of distractions and background noise, because you'll need to be able to hear clearly. You must be alone, because having other people in the room could affect your test responses. We recommend that you do not use headphones/earphones/earbuds or high volume. The test takes about 10 minutes.

You will hear a number of well-known tunes. Some will be played correctly, while others will be played incorrectly (with some wrong notes). Your task is to decide whether the tunes are played correctly or incorrectly.

Here's an example to show you what to expect. Click the link below that says "Play example tune." Listen carefully. If you think the tune was played correctly, click the button labeled "Yes" for the question. If you think the tune was played incorrectly, click the button labeled "No."
