You don't need to read music to take this test, only to know the seven letter names of the notes. If they are new to you, start with White keys only, where there are fewer answers to choose from. Most people, musicians included, score around chance: fewer than one right answer in the 12-note mode. That is completely normal and says nothing about how musical you are.
Trained musicians should know one catch. After each answer the test shows the right note, so a good ear can work out the next note from the interval between the two. That is relative pitch, a valuable skill but a different one. For a strict check of absolute pitch, use All 12 notes, skip the test sound right before you start (it is a middle C), pause for 10 to 15 seconds or hum an unrelated tune between notes, and retake the test on another day.
People with absolute pitch score high from the very first note, every time. Not sure which skill you are using? The guide to perfect pitch vs relative pitch explains the difference and how to train each. If naming notes feels impossible, try the tone deaf test, which needs no note names, or browse the other free voice tests.
