Septimal meantone example?
The introduction has "On the other hand, 7-limit meantone (i.e. 5-limit meantone with C–A♯ seen as 7/4) has codimension 2; since 2.3.5.7 is a 4-dimensional JI subgroup, you need two commas (81/80 and 225/224)." Shouldn't that be Harrison's comma instead of 225/224? Lucius Chiaraviglio (talk) 16:45, 28 March 2025 (UTC)
