Temperaments & Tuning, Part VI

(con't from Part V)
The problem organ tuners have in their travels, no matter where they go, is that pesky little mathematical anomaly called the Pythagorean comma [see blog, Temperaments and Tuning, Part II].
It's small (24 Cents) ... not quite a quarter semitone ... but it's too big to fit inside the Circle when intervals are tuned pure, so the tuners have to figure out where to hide it ... where to dump it ... how to divide it and squeeze it in ... somewhere ... among all those pure intervals.
They find a place to do that, when they make their turn here.
