[UC-ODDMUSIC] 88-cent equal temperament choir meets tomorrow at 1:00!

[Andrew Heathwaite]

The group that met tonight for the Microtonal Design UnConference Meet and Greet 
has an interest in singing together in a tuning called 88-cent equal 
temperament, towards generating pieces and performing them this week.  None of 
us have tried this yet.  You can join us!

We're meeting from 1:00 to 2:30 tomorrow (Wednesday 4/20) at the Family Room of 
the IMC, then from 10 am to noon the next day (Thursday 4/21) at "the Mansion" 
(606 Ohio St, Urbana).  We're likely to meet again after that and perform on 
Thursday night for the Performatorium (7:30 to 9:30) and/or the Oddmusic 
Instrument Expo (Saturday 4/23, 2 to 5).  I mention all that to give you a good 
idea of the commitment involved, if you don't already know.  We're in the throes 
of an UnConference, after all!

If you'd like to join us and you weren't in the group that met tonight (it's 
entry level -- like I said, none of us have done this before) then please email 
me.  We'd love to have you!

Much love,
Andrew

88-cent equal temperament (or 88cET) is a tuning system derived by stacking an 
interval of 88 cents (that's exactly 88% of a 12-equal half step).  The tuning 
thus generated contains no octaves!  The octave is 1200 cents.  See how 88cET 
misses the octave:

88
176
264
352
440
528
616
704
792
880
968
1056
1144
1232
...

This is only one of the intriguing things about this tuning.  Come tomorrow to 
find out more!
