15L 1s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 15 large steps and 1 small step, repeating every octave. 15L 1s is related to 1L 9s, expanding it by 6 tones. Generators that produce this scale range from 75¢ to 80¢, or from 1120¢ to 1125¢. Scales of this form are always proper because there is only one small step. It is notable for corresponding to valentine[16].
