101 equal divisions of the tritave, perfect twelfth, or 3rd harmonic (abbreviated 101edt or 101ed3), is a nonoctave tuning system that divides the interval of 3/1 into 101 equal parts of about 18.8 ¢ each. Each step represents a frequency ratio of 3^1/101, or the 101st root of 3. It corresponds to 63.7240edo.
