Wizard

Wizard is a half-octave temperament generated by a wide whole tone of about 217 cents which is the semi-octave complement of ~5/4. Six generators minus a semi-octave represents 3/2, and ten generators minus a full octave represents 7/4, tempering out the commas 225/224 and 118098/117649.

Three generator steps may be identified with 16/11, and the generator itself is close in size to 17/15, which if used, would imply the semi-octave represents 17/12~24/17 and that 17/16 is obtained by stacking six generators octave reduced. As such, it is most naturally viewed as a temperament of the 2.3.5.7.11.17 subgroup, where it tempers out 225/224, 289/288, 385/384, and 561/560.

72edo, 94edo, and especially 166edo are among the good tuning options.

The name wizard appeared as early as 2003, presumably given by Gene Ward Smith[1].
