124 equal divisions of the tritave, perfect twelfth, or 3rd harmonic (abbreviated 124edt or 124ed3), is a nonoctave tuning system that divides the interval of 3/1 into 124 equal parts of about 15.3⁠ ⁠¢ each. Each step represents a frequency ratio of 3^1/124, or the 124th root of 3.

Theory

This tuning is enfactored in the 7-limit. Using the patent val, it tempers out 128/125 in the 5-limit; 126/125 and 64/63 in the 7-limit; 120/119 in the 17-limit; 96/95 in the 19-limit; 92/91 in the 23-limit; 116/115 in the 29-limit; 112/111 in the 37-limit; and 106/105 in the 53-limit.
