Savart

The savart /səˈvɑːr/ is a unit of measurement for musical pitch intervals ( play ). One savart is equal to one thousandth of a decade (10/1: 3,986.313714 cents): 3.9863 cents. Musically, in just intonation, the interval of a decade is precisely a just major twenty-fourth, or, in other words, three octaves and a just major third. Today the savart has largely been replaced by the cent and the millioctave. The savart is practically the same as the earlier heptameride (eptameride), one seventh of a meride. One tenth of an heptameride is a decameride and a hundredth of an heptameride (thousandth of a decade) is a jot.

If ${\displaystyle {\frac {f_{2}}{f_{1}}}}$ is the ratio of frequencies of a given interval, the corresponding measure in savarts is given by:
