None of us have tried this yet. You can join us!<br><br>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!<br><br>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!<br><br>Much love,<br>Andrew<br><br>= = = = =<br><br>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:<br><br>88<br>176<br>264<br>352<br>440<br>528<br>616<br>704<br>792<br>880<br>968<br>1056<br>1144<br>1232<br>...<br><br>This is only one of the intriguing things about this tuning. Come tomorrow to find out more!<br></div>
