80et provides the [[optimal patent val]] for 5-limit [[diaschismic]], for 13-limit [[srutal]], and for 7-, 11- and 13-limit [[bidia]]. It is a good tuning for various temperaments in [[canou family]], especially in higher limits. | 80et provides the [[optimal patent val]] for 5-limit [[diaschismic]], for 13-limit [[srutal]], and for 7-, 11- and 13-limit [[bidia]].

80et supports a profusion of 19-limit (and lower) rank two temperaments which have mostly not been explored. We might mention: | |||
31&80 <<7 6 15 27 -24 -23 -20 ... || | |||
72&80 <<24 30 40 24 32 24 0 ... || | |||

58&80 <<6 -10 12 -14 -32 6 40 ... || | |||
41&80 <<7 26 25 -3 -24 -33 20 ... || | |||
In each case, the numbers joined by an ampersand represent 19-limit [[patent val]]s (meaning obtained by rounding to the nearest integer) and the first and most important part of the wedgie is given. | |||
