Got three minutes?

by Eszter Hargittai on October 27, 2006

Click here for something cool.

in three minutes, the largest dot will travel around the circle once, the next largest dot will travel around the circle twice, the next largest dot three times, and so on.

the dots are arranged to trigger notes on a chromatic scale when they pass the line

Cool indeed. Fave is — very trippy.


John Quiggin 10.27.06 at 3:52 am

It is cool!

Wonderful stuff! Thanks!

The microtones are particularly cool.

For anyone impatient, I’d say it’s worth it just to see all the dots cross the line at the same time.

“Primes Only” strikes my ear as more melifluous than “Non-Primes Only”, which is the opposite of what I would have expected.

Microtones are my favorite. Would love to hear that stereoized and mapped on primes or the Fibonacci series.

what struck me was how dependent the visual and aural elements were on each other for interest, as each is not really that exciting on its own. But total effect is rather novel, and the variations on the theme are clever. I do like good ideas for process music.

Sweet. Thanks.

Rich b — perhaps that’s just because there are more non-primes, so more opportunities for dissonance?


Thompsaj 10.27.06 at 9:59 pm

only one more non-prime than prime, more likely that adjacent tones like 0,1 and 8,9,10 and the tritone at 6 are more dissonant than the comparatively well-spaced prime pitch classes, 2,3,5,7,11.

“3 minutes”
Yeah, right.

With the primes, you simply don’t get any big many-note chords.
