6L 25s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 6 large steps and 25 small steps, repeating every octave. 6L 25s is related to 6L 1s, expanding it by 24 tones. Generators that produce this scale range from 193.5 ¢ to 200 ¢, or from 1000 ¢ to 1006.5 ¢.

Soft-of-basic tunings are associated with hemiwurschmidt temperament, being its 31-note MOS, while hyposoft and hypohard tunings are associated with sharp didacus extensions, namely roulette and mediantone.
