7/1/13: The Shepard Tone

This blew my freakin' mind.


When multiple octaves are played at once, our brain likes to focus on just one of them, usually the lowest one, as a sort of "base tone."  This makes notes easier to process, as even the most simple notes can have multiple tones that would provide an abundance of distracting information.

Here's the crazy part.

Since the brain is hard wired to look for patterns and continuity, it unconsciously (or consciously, however you want to look at it) perceives the next octave in the series.  So as you continuously replay the video, the notes seem to get higher and higher, even though you're listening to the same thing, and those notes were there all along.

Shit's bananas.

Suant:  Spread equally/evenly over a surface.

The suant icing was layered on top of the cake, like freshly laid cement, but more appetizing.
