Other Tuning Systems
(other than LucyTuning)

Many tuning arrangements have been used in various cultures over the centuries. New systems are still being devised and experimented with, and all may be considered to fall into one or more of the categories below:

Pythagorean Tuning - (from cumulative steps of 3/2 and 4/3)

12tET breaks the octave into twelve equal semitones. Many integers other than 12 have been used in the last two centuries principally experimentally, and in the West.
Equal Temperaments some of which may also be considered as specific meantone tunings and mapped as Large and small intervals

Meantone tunings - (spirals of fourths and fifths)
Just Intonation - (small whole number frequency ratios)
