Wouldn't that be a great name for a band?

My super-cool drum teacher Frank used this term today: aural illusion. It was in reference to poly-rhythms blending together and creating a new sound that neither drum makes on its own but two (or more) drums can make together. If I were a poet, this is what I would write about. It is so beautiful. Or maybe that would be like dancing about architecture. dunno. All I can say is that it makes my head spin and I love it. So when I got home, I looked up aural illusion and found this interesting stuff about "Shephard's tones".

Check it out:

If you play it slowly (twelve tones in a continuous loop), you will hear each tone as one higher than the previous one even though there are only 12 tones. That is the staircase effect. If you play it faster, the effect disappears. You might like this if you are one of those people who downloaded the video of the 6/8 washing machine and listen to it on the sly. You know who you are! ; )

Enjoy and keep listening for those aural illusions!
