Is there an absolute value as a percent wavelength that is a 'cent'? I understand the stuff about beats but not how to get different tones to beat at the same time based on the degree of wetness (expressed in 'cents') the the tuning varies from dead on. Thanks for the info.

__. There are 100 cents in the interval between one note in a scale and the next. The kicker on this is that the number of Hertz (vibrations per seconds) varies between adjacent notes. So, 1 cent is one percent of the distance between one note and the next but the "true distance" varies based up whether they're low or high notes.

__. Um, this isn't a very good explanation, is it?

There are some sound files illustrating degrees of wetness at the bottom of this web page:

I looked up on the link to listen to the samples.
There isn't a huge difference. It's very interesting anyhow.
