10 equal divisions of 8/3 (abbreviated 10ed8/3) is a nonoctave tuning system that divides the interval of 8/3 into 10 equal parts of about 170 ¢ each. Each step represents a frequency ratio of (8/3)1/10, or the 10th root of 8/3.

Theory

10ed8/3 can be seen as a very compressed version of 7edo. The octave compression results in a more accurate perfect fourth, at the expense of the fifth, which becomes a sharp Mavila fifth.
