Call me a heretic, but I'm beginning to wonder if these properties aren't as important as I'd once thought they were. Look at the success of the minor pentatonic in Japan, for example.

Shame on me, but I don't even know what these measure signify. Help, please.

The minor pentatonic scale is MOS and strictly proper, but other Japanese scales are among the most important examples of scales that are not MOS, proper, or distributionally even (John Clough's term for a scale with two step sizes and no more than two specific sizes for each generic interval). Other important examples are the jazz (ascending) melodic minor scale and the various scales containing augmented seconds.

?? I don't think we're talking about the same scale. I mean the one that's approximated in 12TET by 2-1-4-1-4.
