12L 19s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 12 large steps and 19 small steps, repeating every octave. 12L 19s is a great-grandchild scale of 5L 2s, expanding it by 24 tones. Generators that produce this scale range from 696.8 ¢ to 700 ¢, or from 500 ¢ to 503.2 ¢. It is associated with sharper meantone temperaments.
