Press the "repeat" button to test your skills. The answer is displayed a moment after each interval is played. Only checked intervals will be repeated.
This Demonstration tests your ability to determine musical intervals by playing random intervals and then showing the solution after a brief delay. The various options let you control difficulty; a low frequency range (around middle C) with a fixed root is easier, whereas a high frequency range using compound intervals allows any two notes on a standard piano. Only checked intervals are included in the test.
