________________________________________________________________________ Date: Mon, 15 Dec 1997. Subject: series of improving equal temperaments In each series below, each term represents the number of notes in the simplest equal temperament that improves upon the accuracy of the previous one. Tunings in parentheses are the second-best for up to that many notes. I don't go beyond 200TET. Accuracy is defined with respect to JI in the indicated odd limit; equal temperaments not consistent within the given limit are excluded. 3-limit: 1 2 3 5 7 12 (17) (24) 29 41 53 (65) (94) (106) 200 5-limit: 3 (4) 5 7 (8) (9) (10) 12 (15) 19 (22) 31 34 (46) 53 (65) (87) 118 (137) (152) 171 7-limit: 4 (5) 6 9 10 12 15 (16) 19 22 (26) 27 31 (37) (41) (53) (62) 68 72 99 (103) (130) 140 171 9-limit: 5 12 19 22 27 31 41 (46) 53 (58) 72 (77) (94) 99 (118) (130) 171 11-limit: 22 (26) (29) 31 41 (46) 58 72 (80) (87) (94) (111) 118 (130) 152 (159) (176) (183) (198) 13-limit: 26 29 41 46 58 72 (80) 87 111 130 (149) (159) 166 183 190 198 15-limit: 29 41 58 72 (80) 87 (94) 111 121 130 (149) (159) 183 190 17-limit: 58 72 (80) 94 111 121 149 159 183 19-limit: 80 94 111 121 21-limit: 94 111 23-limit: 94 ________________________________________________________________________
