1759 equal divisions of the octave (abbreviated 1759edo or 1759ed2), also called 1759-tone equal temperament (1759tet) or 1759 equal temperament (1759et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 1759 equal parts of about 0.682 ¢ each. Each step represents a frequency ratio of 21/1759, or the 1759th root of 2.
Theory
1759edo is consistent to the 23-odd-limit, tempering out 3025/3024, 2500/2499, 5985/5984, 4225/4224, 6175/6174, 3520/3519, 14875/14872 and 256000/255879. It supports etampesic. Essentially tempered chords in 1759et include vicetertismic chords.
