microtonal articles

For anyone who might be interested, these are a couple of interesting
microtonal articles that I've come across recently...

<http://sites.netscape.net/ricktagawa/24tet>

This is a (anonymously annotated) version of Charles Ives' essay "Some
Quarter-tone Impressions."

<http://stereosociety.com/body_jrpolymi.html>

This is Johnny Reinhard's excellent microtonal "Raison d'�tre."

BTW, In the Ives essay, the anonymous annotator writes that Ives'
feeling that the basic chords should have four or more notes finds
support in the theories of Joseph Yasser, and that the basic chords of
Yasser's system are hexads... What were these chords again? And what
exactly was their relation to Scriabin's "Mystic Chord," the Chord of
the Pleroma? (I have read Yasser, but it was a long time ago now, and
it was also an inter library loan, so I can't easily access the info
and I also seem to have unfortunately forgotten most of the
particulars.)

thanks,

Whoops. Looking at the URL, I now see that these are probably --
sometimes TD contributor, right? -- Rick Tagawa's commentaries...

In 19-tone equal temperament, the basic hexad is an exceedingly rough
approximation of 8:9:10:11:13:14, constucted from every other note in
the usual 12-out-of-19-tET scale.

Yasser claimed that Scriabin was in some sense reaching for this
hexad with his mystic chord.
