MEANTONE PURE MINOR 3rd
This temperament is built with fifths narrowed by 1/3 of syntonic comma. The wolf fifth on G# is very
large and completely unusable. The nine minor thirds based on C, G, D, A, E, B, F#, C#, G# are pure.
The eight major thirds based on Eb, Bb, F, C, G, D, A, E, are narrower, with respect to the pure, by 1/3 of
syntonic comma. Again in this temperament the chromatic scale has a particular character.

on G#. Eight third majors are usable and reduced by 1/7 of syntonic comma.
