Many medieval dances were cast in two sections -- dance and after dance.
There was usually a slow-moving section in duple time followed by a faster
section in triple time. Sometimes the section in triple time was
based on the same melody as the first or duple section. Because of
the improvisatory nature of these dances, very few have come to us in notation.
The dance form most commonly notated in the 13th and 14th centuries
was the estampie. It is similar to the vocal sequence
and consists of a number of sections called puncti, which were repeated.
Its form is AA BB CC.
