Flattertone tunings are even flatter than that of [[26edo]]. Here, 17 fourths get to the interval class for 7, so that [[7/4]] is a double-augmented sixth (C-Ax). [[26edo]] and [[33edo]] are the two primary flattertone tunings. Any flatter than this, the meantone mapping for 5/4 is too inaccurate (it becomes more of a [[16/13]] or [[27/22]]), and [[deeptone]] temperament's mapping is more logical. | Flattertone tunings are even flatter than that of [[26edo]].
