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.
