2L 9s⟨3/1⟩ is a 3/1-equivalent (tritave-equivalent) moment of symmetry scale containing 2 large steps and 9 small steps, repeating every interval of 3/1 (1902.0 ¢). Generators that produce this scale range from 864.5 ¢ to 951 ¢, or from 951 ¢ to 1037.4 ¢. The generators of this scale in the hard-of-basic region approximate 5/3. It is a scale of the Arcturus temperament.
