44ed6 divides the perfect nineteenth (6:1 ratio) into 44 equal tones of 70.499 cents each. It is closely related to 17edo and 27edt, and like them is an excellent no-fives tuning in the 13 odd limit. It also has good matches for the 23rd and 25th harmonics. Like 27edt, its octaves are slightly flat, albeit less so. The octave of 44ed6 is 1198.48 cents: about a cent and a half flat. The third harmonic (tritave) is sharp by the same amount, while the 7th, 11th, and 13th harmonics are all sharp by 15, 8, and 0.9 cents, respectively.
