How well can you distinguish subtle differences in rhythm?

This test will play a series of two rhythmical phrases and ask you if they are the same or different. Unlike the similar tonedeaf test, however, the differences between the phrases are only rhythmical.

Recent research has emerged suggesting that rhythm perception and pitch perception deficits may be linked. I thought it would be interesting to make a test that would give an objective measure of rhythm perception. There is also a large degree of "rhythm memory" that is also incidentally tested. It is far easier to remember melodies than it is rhythms: give this test a try, you will quickly see how difficult it is!

At the end of the test, you can compare your performance to that of over 7,000 subjects who had previously submitted their scores.

You will need Flash for this test. Please be patient, as it may take a few minutes to load.
