10 equal divisions of the tritave, perfect twelfth, or 3rd harmonic (abbreviated 10edt or 10ed3), is a nonoctave tuning system that divides the interval of 3/1 into 10 equal parts of about 190 ¢ each. Each step represents a frequency ratio of 31/10, or the 10th root of 3.
Theory
10edt has very accurate 5-limit harmony for such a small number of steps per tritave, most notably the 5/4 inherited from 5edt. 10edt introduces some new harmonic properties though — such as the 571 cent tritone, which can function as 7/5. We can use this to readily construct chords such as 4:5:7:12, although the 7/4, being 18 cents flat, does considerable damage to the consonance of this chord.
10edt also splits the major third in half, categorizing this tuning as a fringe variety of "meantone" temperament.
One step of 10edt can serve as the generator for pocus temperament, a merge of sensamagic and 2.3.5.7.13 catakleismic, which tempers out 169/168, 225/224, and 245/243 in the 2.3.5.7.13 subgroup.
