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 Today, musical use of the savart has largely been replaced by the cent and the millioctave.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 (play^ⓘ). One tenth of an heptameride is a decameride (play^ⓘ) and a hundredth of an heptameride (thousandth of a decade) is approximately one jot (play^ⓘ).
