Kite's ups and downs notation: Difference between revisions
Added to the explanation of enharmonic intervals. Added a "placement" section about ^B vs. B^. Added to the explanation of sharp-1, sharp-2, etc. Added an explanation of single-ring vs multi-ring. Added the enharmonic intervals for each edo 12-24. |

Sharp-1, flat-2, etc. refer to the number of EDOsteps made by seven 5ths minus four 8ves. All sharp-1 and flat-1 edos can be notated without ups and downs, because the up is exactly equivalent to a sharp or flat. | Sharp-1, flat-2, etc. refer to the number of EDOsteps made by seven 5ths minus four 8ves.

A ring is a circle of 5ths. In multi-ring edos like 14, 15 and 24, a single ring doesn't contain all the edo's notes. In contrast, edos like 12, 19 and 22 are single-ring.

In contrast, edos like 12, 19 and 22 are single-ring. It's possible to notate any single-ring edo with conventional notation if notes are permitted to be out of order (e.g. 22edo could have C Db B# C#). But multi-ring edos absolutely require ups and downs. | ||
