Template:EDO intro

Using the patent val, the equal temperament tempers out 4000/3969, 10976/10935 and 65625/65536.

The non-patent val 162 257 377] (162c) and its extensions are of considerable interest, as this tempers out 2048/2025. In the 7-limit, 162 257 377 455] tempers out 126/125 and 2048/2025 both, giving a tuning for 7-limit diaschismic. In the 11-limit 162 257 377 455 561] (162ce) tempers out 126/125, 176/175 and 896/891, and so supports 11-limit diaschismic, and in fact has a fifth only 0.01 cents flatter than the POTE tuning. The 13-limit is even closer: 162 257 377 455 561 600] (162cef) tempers out 126/125, 176/175, 196/195, 364/363 giving 13-limit diaschismic, and the fifth of 95\162 is a mere 0.0000383 cents sharp of the 13-limit POTE tuning.
