Frequency ratio '''7/4''', measuring approximately 968.8 [[cent]]s, named '''harmonic seventh''' or '''natural seventh''', represents the interval between the 4th and 7th harmonics in the [[harmonic series]]. It is also called a '''septimal minor seventh''' or '''subminor seventh''' – the word "septimal" referring to the presence of a 7 as the highest [[prime]] in the ratio, and the word "subminor" referring to the harmonic seventh's narrowness compared with a traditional minor seventh (such as [[9/5]] or [[16/9]], [[12edo]]'s 1000-cent interval, or a minor seventh found in a meantone system). While many microtonalists see 7/4 as being strictly a type of seventh, [[User:Aura|Aura]] is one of perhaps only a handful of microtonalists at most to [[User:Aura/Aura's Ideas on Functional Harmony #Interstep Functions|offer a counterargument]].
