Here's the Dave Liebman Master Class I referred to in the post about rhythm that is moving towards talking about "wrong notes". In my first nearly OT comment, I mentioned that if you listen to the notes B and C played together (minor second), they definitely sound dissonant, even jarring. Put a note on each side, E B C G (3 7 1 5) and they make a particularly beautiful inversion of C major 7th. The first pair, E B and the second pair, C G are both fifths, the second most consonant interval in the spectrum.
I'm not sure if Dave L. gets into rhythm in this, but his harmony talk is very good, expressing many thoughts I have lived with way before I saw this. One example is how consonance has evolved from octave, to fifth, to third and then - the Devil's Interval, the tritone (what gives the dominant seventh its distinctive sound). Moving to 11th, 13th and beyond (13b9 and further). In other words, the western notion of consonant harmony follows the physics of the harmonic series. My theory, which I probably heard somewhere like Schillinger, is that complexity is less scary as time moves on. And this is also true of rhythmic complexity, with binary and trinary, etc.
