My tuning scheme involves 33 equal divisions of the pure fourth.
My tuning scheme involves [[33ed4/3|33 equal divisions of the pure fourth]].


1. [log (4/3) * 1200]/(log 2) divided by 33 = 15.092272701048866128954947492807 cents.
1. [log (4/3) * 1200]/(log 2) divided by 33 = 15.092272701048866128954947492807 [[cents]].


2. Carry the comma to the 79th step and you reach 1192.2895433828604241874408519317 cents.
2. Carry the [[comma]] to the 79th step and you reach 1192.2895433828604241874408519317 cents.


3. Complete the octave to 1200 cents and move the 22.802729318188441941514095561079 cent comma between steps 45-46. You do this by key transposing the tuning to the -46th step.

Voila! You now have a circulating temperament which is practically a subset of 159-tET. There are three sizes of fifths by which one can formulate diatonical scales:

Some degrees yield excellent 11 limit results, while others produce adorable 5 limit and sufficiently close 7 limit intervals. I had implemented this tuning on my special Qanun, and also installed Wittner fine-tuners to the strings for accuracy of pitch. Although my hands are still numb from all that tuning, I am very pleased, and so are Qanun performers who were "unfortunate" enough to have met me.
