- thanks very much! A while back I wanted to carefully study the math of various historically important tuning systems, mainly these:

• Pythagorean tuning.

• just intonation systems, and especially Ptolemy’s intense diatonic scale.

• meantone temperament, and especially quarter-comma meantone, which was introduced around 1550, and then replaced just intonation, at least for keyboard music.

• a few of the most popular well-tempered scales, which starting becoming popular roughly around 1690.

• the equal-tempered 12-tone scale, which took over around 1900.

But there are actually so many well-tempered scales I doubt I'll get through most of them! These days I've got just intonation on my mind.
