8L 7s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 8 large steps and 7 small steps, repeating every octave. 8L 7s is a child scale of 7L 1s, expanding it by 7 tones. Generators that produce this scale range from 1040 ¢ to 1050 ¢, or from 150 ¢ to 160 ¢. This scale is the chromatic scale of Opossum temperament

Under opossum temperament, the tetrad 1/1-6/5-10/7-12/7 (0¢-316¢-617¢-933¢) can be formed by by stacking the dark generator 2, 4, and 6 times above the root. 8L 7s approximates this tetrad from 0¢-300¢-600¢-900¢ to 0¢-320¢-640¢-960¢. Template:Scale tree
