| If you use two neighboring numbers from Fibonacci Series 1 1 2 3 5 8 13 21... you get the following approximations:

| 1, 1 -> [[7edo]]

| 1, 2 -> [[12edo]]
| |
| 2, 3 -> [[19edo]]
| |
| 3, 5 -> [[31edo]]

| Graham Breed [[http://x31eq.com/meantone.htm|writes]]: //I think of this as the standard melodic meantone because the all these ratios are the same. It has the mellow sound of 1/4 comma, but does still have a character of its own. Some algorithms make this almost exactly the optimum 5-limit tuning. It's fairly good as a 7-limit tuning as well. Almost the optimum (according to me) for diminished sevenths. I toyed with this as a guitar tuning, but rejected it because 4:6:9 chords aren't quite good enough. That is, the poor fifth leads to a sludgy major ninth.//
