'''6ED6''' is the [[Ed6|equal division of the sixth harmonic]] into six parts of 516.9925 [[cent|cents]] each, corresponding to 2.3211 [[edo]]. It is related to the [[Breedsmic temperaments|harry temperament]], which tempers out 243/242, 441/440, and 4000/3993 in the 11-limit.

This page presents a topic of primarily mathematical interest.

While it is derived from sound mathematical principles, its applications in terms of utility for actual music may be limited, highly contrived, or as yet unknown.

Special properties

6 equal divisions of the 6th harmonic (abbreviated 6ed6) is a nonoctave tuning system that divides the interval of 6/1 into 6 equal parts of about 517 ¢ each. Each step represents a frequency ratio of 61/6, or the 6th root of 6.

Theory

6ed6 corresponds to 2.3211…edo. It is the generator chain for the harry temperament.
