Maths vs. Music - Tuning and harmony

[bennyboy]

I found a VST synth that allows custom scale tunings, and found a just intonation scale.  I didn't set the scale frequencies myself, but I think they're right because I got the effect I expected. Here are two cadences repeated with a simple saw/square tooth sound, first with just intonation(i.e. all notes tuned to low-integer ratios based on the tonic), and second with equal-tempered tuning (freq. * 2^n/12).  You can really hear the "chorus" effect-- it's almost hard to believe that I didn't add an actual chorus effect, isn't it?

Also, sorry about the big LoL banner, but AF's soundcloud support doesn't currently allow for resizing.
