607 equal divisions of the octave (abbreviated 607edo or 607ed2), also called 607-tone equal temperament (607tet) or 607 equal temperament (607et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 607 equal parts of about 1.98 ¢ each. Each step represents a frequency ratio of 21/607, or the 607th root of 2.

Theory

607edo is consistent to the 9-odd-limit. Using the patent val, the equal temperament tempers out 32805/32768, 420175/419904 and 244140625/243045684 in the 7-limit; 3025/3024, 6250/6237, 32805/32768 and 420175/419904 in the 11-limit. It supports countertertiaschis. Essentially tempered chords available in 607et include baladismic chords and xenismic chords.
