:: Hello, I am not familiar with English mathematics terminology, [[Fifthspan]] is an example counting "spans", not measuring the size of span. You know, "multiple-span bridge" has one or more pier and spans the river bank and the pier, and spans further. They are easy to distinguish in writing; the span of 9/8 is 203.9 cents, and ~9/8 is +2 span of ~3/2. (This is an example of duality between tuning space and interval space?) So, is it particular technical term? --[[User:Dummy index|Dummy index]] ([[User talk:Dummy index|talk]]) 14:11, 23 December 2021 (UTC)

::: (Maybe fifthspan doesn't mean fifth-size span. Linear span...? If so, why do we need to define the linear subspace of rank-2 temperament, its dimension is already reduced? Or does "span" always mean "use this set of vectors as the basis?") --[[User:Dummy index|Dummy index]] ([[User talk:Dummy index|talk]]) 15:13, 24 December 2021 (UTC)

::: Ah, span (v.) and subtend (v.) are used interchangeably on [[Constant structure]], and [[Glossary #S]], fifthspan may be "The number of fifths an interval subtends" (as one action of spanning). --[[User:Dummy index|Dummy index]] ([[User talk:Dummy index|talk]]) 13:49, 12 December 2024 (UTC)
