'''19 equal divisions of the [[18/5]]''' (abbreviated '''19ed18/5'''), when viewed under a regular temperament perspective, is the tuning system that divides the 18/5 interval into 19 equal parts of about 116.7 ¢ each. Each step of 19ed18/5 represents a frequency ratio of (18/5)<sup>1/19</sup>, or the 19th root of 18/5. | |||
19ed18/5 is most notable for the fact that its one step is defined as '''[[secor]]'''. | |||

If considered in its own right, the regular temperament has good approximations for harmonics [[5/1|5]], [[7/1|7]], [[8/1|8]], and [[12/1|12]], all being sharp by roughly the same amount, therefore making the 18/5.5.7.8.12 subgroup the best for this tuning. There, it tempers out [[81/80]], [[126/125]], [[225/224]], [[1728/1715]], [[5103/5000]]. | If considered in its own right, the regular temperament has good approximations for harmonics [[5/1|5]], [[7/1|7]], [[8/1|8]], and [[12/1|12]], all being sharp by roughly the same amount, therefore making the 18/5.5.7.8.12 subgroup the best for this tuning.
