text needs to pass "clearance"

If I may "indulge" listers for just a minute... The following text
for my new piece VIOLAHEXY needs to pass clearance. Is there
anything egregiously wrong with it??

Please keep in mind, it is intended for your ABSOLUTELY uninformed
violist... microtonally speaking, that is.

This is just a little practical question. If I hear nothing, I'll
assume I did "OK"

_________________
VIOLAHEXY, for viola and synthesizer (on audio CD), is written in an
"alternate tuning system," meaning in a system other than our "usual"
system of 12 tempered pitches per octave. The basic scale is created
through combining "hexanies" -- 6-note structures made by simple
multiplication of factors. These hexanies are known as "combination
product sets" or CPSs for short.

In order to play this piece, one need only read traditional notation
and quartertones (see chart at beginning of piece) with numbers near
the note heads which "adjust" the pitches + or - in cents from the
nearest quartertone. By traditional definition, there are 100 cents
per semitone, 50 cents per quartertone, and there will never be more
than 25 cents deviation from the nearest quartertone in this system.

Hexanies create consonant scales. You will see in the accompanying
chart that several of the ratios found in this scale are in small
integer relationships to the fundamental pitch "C" (261 Hz.) You will
find 3/2, the just perfect fifth, 5/4, the just major third, and 7/4,
the just minor seventh. Therefore, the music is related to just
intonation, and can be quite consonant.

THE AUDIO CD:

In order to facilitate an accurate rendering of this composition, I
have included "practice" tracks on the audio CD which also includes
the synthesizer part that will be played during performance.

TRACK 1 is a slow ascending scale in this system -- for practice
purposes only. Note that this scale is "octave equivalent," meaning
each octave has the same pitch classes as octaves above and below it.
Slow practice of this scale will facilitate hearing the system.

TRACK 2 is the piece WITH an electronic PRACTICE viola part (NOT FOR
CONCERT). One may play along with this track for practice in order
to become familiar with the microtonal pitches of the viola part and
with the structure of the piece.

TRACK 3 is the CONCERT track WITHOUT the practice viola part. This
track is to be played IN CONCERT WITH the live viola. Please note
that the viola "cues" from the synthesizer are very simple to
facilitate coordination.

Above all, enjoy! VIOLAHEXY, although in an unusual tuning system,
is expressive, and all the traditional nuances of traditional music
making should be brought to it!
