19L 8s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 19 large steps and 8 small steps, repeating every octave. 19L 8s is a great-grandchild scale of 3L 5s, expanding it by 19 tones. Generators that produce this scale range from 755.6 ¢ to 757.9 ¢, or from 442.1 ¢ to 444.4 ¢. This scale is primarily associated with sensi and variants thereof, especially the more accurate sensipent extensions such as sensible and sendai.
