8L 11s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 8 large steps and 11 small steps, repeating every octave. 8L 11s is a grandchild scale of 3L 5s, expanding it by 11 tones. Generators that produce this scale range from 442.1 ¢ to 450 ¢, or from 750 ¢ to 757.9 ¢. This scale is primarily associated with sensi and variants thereof, especially the more accurate sensipent extensions such as sensible and sendai.
