Kite's thoughts on the arrows of ups and down notation

In N-edo, "arrow" means 1\N, and is thus a synonym for edostep (but see the exceptions and extensions below).

"Arrow" refers to the up-arrows and down-arrows (^ and v) used in ups and downs notation to raise or lower by one edostep. Just as "bar" (the vertical line that separates measures) has come to mean "measure", the name of the notation symbol now means that which the symbol indicates. Thus in 22edo, 5/4 is one arrow lower than 9/7, and two arrows lower than 4/3.

When applied to sharp-1 edos like 19edo, "arrow" is somewhat counter-intuitive, because 19edo doesn't use ups and downs. Nevertheless, by analogy with other edos, in a 19edo context "arrow" means 1\19.

In some very large edos (e.g. 205edo#Notation), an up or down may indicate multiple edosteps, and one edostep may be indicated by a lift or a drop (written / or \). In such edos, "arrow" refers to multiple edosteps and "slant" refers to a single edostep.

In pergen notations, the terms arrows and slants are used similarly. Thus one arrow in Triyo equals a tempered 81/80.

This use of the term "arrow" was coined by Kite Giedraitis.
