Original Wikitext content:

In [[Just Intonation]], **5/4** is the frequency ratio between the 5th and 4th harmonics. Measuring about 386.3[[Cent|¢]], it is about 13.7¢ away from [[12edo]]'s major third of 400¢. It has a distinctive "sweet" sound, and has been described as more "laid back" than its 12edo counterpart. Providing a novel consonance after 3, it is the basis for [[5-limit]] harmony. It is distinguished from the [[Pythagorean]] major third of [[81_64|81/64]] by the syntonic comma of [[81_80|81/80]], which measures about 21.5¢. 81/64 and 5/4 are both just intonation "major thirds," 81/64 having a more active and discordant quality, 5/4 sounding more "restful".

In the context of the harmonic series, 5/4 can be heard between the 4th and 5th member of the series, demonstrated here melodically in singing into a resonant udderbot (from the fundamental up to 5 and then noodling between 5 and 4). [[file:5-4.mp3]] Hear it?

5/4 converted to cents (¢): 1200 * log (5/4) / log (2) = 386.314...

When two notes sound a 5/4 together,

5/4 the interval, like all //intervals//, refers to a //relation// between two pitches. We speak of this relation (one pitch beating 5/4 times as fast as the other) after we are able to distinguish it from other relations.

In relation to 12 tone equal, 5/4 is about 13.7¢ flatter than the 4th degree (400¢). 5/4 the interval has been called the //perfect major third// to distinguish it from the other intervals in that neighborhood.
