Information The goal of this study is to determine whether Absolute Pitch (AP) differs systematically for different timbres. Participants should have AP, or suspect that they have AP. The procedure consists of a brief survey and an AP test. All of the information you provide will be kept confidential and will be used in this study only. By filling out this survey, you are providing your consent to participate in the survey and the pitch-naming test.

The AP test is divided into 4 blocks of 24 trials. Each block consists of 24 pitches (A3 to Gb5) presented in random order. Each block has a different timbre or instrumental sound. After you hear a tone, you will have 3 seconds to reply before you are presented with the next tone. You can rest as much as you want between blocks. Click on "next test" when you are ready to start it. The entire procedure takes about 15 minutes.

Your results will be presented once you have finished the fourth block. You will receive 1 point for each correct response, and .75 for each response that is off by a semitone. The maximum score is 24 for each timbre.

The experimenters are Patricia Vanzella (Professor of Music, University of Brasilia) and Glenn Schellenberg (Professor of Psychology, University of Toronto).
