IMPORTED REVISION FROM WIKISPACES
This is an imported revision from Wikispaces. The revision metadata is included below for reference:

The revision contents are below, presented both in the original Wikispaces Wikitext format, and in HTML exactly as Wikispaces rendered it.
Original Wikitext content:
The 87 equal temperament, often abbreviated 87-tET, 87-EDO, or 87-ET, is the scale derived by dividing the octave into 87 equally-sized steps, where each step represents a frequency ratio of 13.79 cents. It is solid as both a 13-limit (or 15 odd limit) and as a 5-limit system, and of course does well enough in any limit in between. It represents the 13-limit tonality diamond both uniquely and consistently, and is the smallest equal temperament to do so. 87et tempers out 196/195, 325/324, 352/351, 364/363, 385/384, 441/440, 625/624, 676/675, and 1001/1000 as well as the 29-comma, <46 -29|, the misty comma, <26 -12 -3|, the kleisma, 15625/15552, 245/243, 1029/1024, 3136/3125, and 5120/5103. Some 13-limit rank two temperaments supported by 87et are these: tritikleismic 72&87 <<18 15 -6 9 42 ... || rodan 41&87 <<3 17 -1 -13 -22 ... || mystery 29&58 <<0 29 29 29 29 ... || countercata 34&87 <<6 5 -31 32 14 ... || luna 31&87 <<15 -2 -5 22 -23 ... || 87 can serve as a MOS in these: 270&87 <<24 -9 -66 12 27 ... || 494&87 <<51 -1 -133 11 32 ... || 224&87 <<27 8 -67 -1 5 ...|| 87et is a particularly good tuning for [[Gamelismic clan|rodan temperament]]. The 8/7 generator of 17\87 is a remarkable 0.00062 cents sharper than the 13-limit [[POTE tuning|POTE]] generator and is close to the 11-limit POTE generator also. Also, the 32/87 generator for [[Kleismic family|clyde temperament]] is 0.04455 cents sharp of the 7-limit POTE generator. Music: * http://www.archive.org/details/Pianodactyl by [[Gene Ward Smith]]
