The above link has three tests, to check if you are tone, pitch, or rhythm deaf. Take the tests and let the rest of us know how you do! I took each twice, just to make sure. ;)
Here are my results:
Pitch test: "At 500 Hz, you can reliably differentiate two tones 2.4 Hz apart."
That's rated as 'normal' on the little legend thing, and it puts me in the 58th percentile. I took it twice, because the first time I kinda rushed through it, but I got the same score on the second one.
Tone test: The first time I got 83.3% correct, even though it said "Even excellent musicians rarely get above 80% correct!" The second time, I got 75% correct. I guess that puts me somewhere between the 46th and 79th percentiles. :confused:
Rhythm test: First time 84%, second time 88%. That puts me somewhere between the 84th and 92nd percentiles.
*warning, by the way: the answers are given at the end of the tone and rhythm ones, so if you want to retake them, be sure to look away!*
