3401 equal divisions of the tritave, perfect twelfth, or 3rd harmonic (abbreviated 3401edt or 3401ed3), is a nonoctave tuning system that divides the interval of 3/1 into 3401 equal parts of about 0.559 ¢ each. Each step represents a frequency ratio of 31/3401, or the 3401st root of 3.
3401edt is notable for being the denominator of a convergent to log3(7/3), after 13edt, 35edt, and 153edt, and the last before 108985edt, and therefore has an extremely accurate approximation to 7/3, only about 5 microcents flat. In fact, 3401edt demonstrates 16-strong 7-3 telicity, even stronger than that of 153edt. It also has a very good approximation to 15/13.
