'''[[Ed5|Division of the 5th harmonic]] into 17 equal parts''' (17ED5) is a good [[hyperpyth]] tuning. The step size is about 163.9008 cents, corresponding to 7.3215 [[EDO]].

A hyperpyth tuning, 17ED5 offers a good compromise between 13/5 and 17/5, but the 9/5 of 983 cents is a little bit flat. However, in hyperpyth, 21/5 isn't necessarily represented, at least not as well. In 17ED5, the 21/5 is represented about as well as the 9/5 is, although that's not too good. Luckily, 27, 29, and 39 do a fair job of it. Nevertheless it's the simplest equal hyperpyth after 5ed5, and quite consonant. I imagine it to be the traditional tonality of the tiny creatures living on subatomic particles.

But wait, an interesting pattern emerges:
But wait, an interesting pattern emerges:


22ED5 focuses on 9/5
[[22ed5|22ED5]] focuses on 9/5


27ED5 focuses on 13/5
[[27ed5|27ED5]] focuses on 13/5


29ED5 focuses on 17/5
[[29ed5|29ED5]] focuses on 17/5


(and 34=17*2)
(and 34=17*2)
Line 15: Line 16:
so: 22+27+29=78=39*2
so: 22+27+29=78=39*2


and behold, of the lot, 39ED5 offers the best balance between those intervals.
