19L 12s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 19 large steps and 12 small steps, repeating every octave. 19L 12s is a great-grandchild scale of 5L 2s, expanding it by 24 tones. Generators that produce this scale range from 503.2¢ to 505.3¢, or from 694.7¢ to 696.8¢.

It is associated with flatter meantone temperaments.
