How this test works

This ear game has two parts and an optional third. First, two tones play and you say whether the second was higher or lower. The difference shrinks after two right answers and grows after a mistake, until it settles near the smallest step you can hear. That step, in cents, is your main score. Second, you tap back 5 short click rhythms. Third, you can name 12 single notes. This up-down method was described in 1971.
