===Hyposoft=== | |||
Hyposoft tunings correspond to meantone temperaments, characterized by flattening the perfect 5th from just (3/2) to achieve a diatonic major 3rd that approximates 5/4 (386¢). Examples of this include 19edo (step ratio 3:2) and 31edo (step ratio 5:3). | |||

=== Parent and daughter MOS scales === | |||
5L 2s has a parent scale of 2L 3s, meaning 5L 2s contains 2L 3s as a subset. 5L 2s also has two daughter scales that both contain 5L 2s as a subset: either 7L 5s (if the step ratio is less than 2:1) or 5L 7s (if the step ratio is greater than 2:1). A step ratio exactly 2:1 will produce an equalized form of both 7L 5s and 5L 7s, corresponding to 12edo. | |||
