Meantone family: Difference between revisions

In flattone tunings, the fifth is even flatter than that of [[19edo]]. Here, 9 fourths get to the interval class for 7, resulting in [[7/4]] being a diminished seventh interval (C-Bbb). Other intervals are [[7/6]], a diminished third (C-Ebb), and [[7/5]], a doubly diminshed fifth (C-Gbb). In general, most septimal subminor intervals are diminished and most septimal supermajor intervals are augmented, which makes it quite easy to learn flattone notation. Good tunings for flattone are [[26edo]], [[45edo]] and [[64edo]].
