89edf is similar to [[Carlos Gamma]] in that it includes a just perfect fifth and an incredibly precise approximation of the major and minor thirds, and is next in line in the sequence {[[1edf|1]], [[2edf|2]], [[5edf|5]], [[7edf|7]], [[9edf|9]], [[11edf|11]], [[20edf|20]], 89, 109, 129, 149} of divisions of the perfect fifth to approximate [[5/4]] with increasing accuracy. | 89edf is similar to [[Carlos Gamma]] in that it includes a just perfect fifth and an incredibly precise approximation of the major and minor thirds, and is next in line in the sequence {[[1edf|1]], [[2edf|2]], [[5edf|5]], [[7edf|7]], [[9edf|9]], [[11edf|11]], [[20edf|20]], 89, 109, 129, 149} of divisions of the perfect fifth to approximate [[5/4]] with increasing accuracy. | ||
