107 equal divisions of the 11th harmonic (abbreviated 107ed11) is a nonoctave tuning system that divides the interval of 11/1 into 107 equal parts of about 38.8 ¢ each. Each step represents a frequency ratio of 11^1/107, or the 107th root of 11.

Theory

107ed11 is related to 31edo, but with the 11/1 rather than the 2/1 being just. The octave is slightly stretched (about 2.7182 ¢, which is almost exactly e cents). Like 31edo, 107ed11 is consistent through the 12-integer-limit.
