Mensuralnotation, NL: ?, DK: ?, S: ?, FI: mensuraalinuotinnus.
A system of duration notation whose principles were first established
in the mid-13th century, and that (with various changes) remained in use
until about 1600. As such, it is the basis for the notation of rhythms
in Western musical notation.
Franco of Cologne (ca. 1250) is credited with the first systematic
explanation of the notationâs principles, so the notation of this
earliest period is called âFranconianâ. Francoâs system made use of
three note values â long, breve, and semibreve â each of which was
normally equivalent to three of the next lower note value.
Then, in the first half of the 14th century, Philippe de Vitry and
Jehan de Murs added several note values (the minim, semiminim and fusa)
and extended Francoâs principles to govern the relationship between
these values. They also put the duple division of note values on an
equal footing with the earlier (preferred) triple division.

White or void mensural notation
In the 15th century, hollow (or void) notes began to substitute for
the earlier solid black ones, which were then free to assume the
function of red (or colored) notes in the earlier notation. ...
