The estampie is similar in form to the
lai, consisting of a succession of repeated notes. Each
puncta has a pair of lines that repeat the same melody, in the form: :
aa, bb, cc, etc.. The two statements of the melody in each punctus differ only in their endings, described as
apertum ("open") and
clausum ("closed") by Grocheio, who believed that six
puncta were standard for the stantipes (his term for the estampie), though he was aware of stantipes with seven
puncta. The structure can therefore be diagrammed as: :
a+x, a+y; b+w, b+z; etc.. In an instrumental estampie, the open and closed endings of the puncta are the same each time, so that the end of the
punctum serves as the refrain, in the form:
a+x, a+y; b+x, b+y, c+x, c+y, etc. He further states that this difficulty captivates the attention of both the players and listeners because of these complications. According to Grocheio, the vocal estampie begins with a refrain, which is repeated at the end of each stanza, with text and melody independent of the stanza. However, surviving songs do not include a section labeled as a refrain, so some scholars suggest that a convention must have existed for choosing lines to use as a refrain. Scholar Elizabeth Eva Leach wrote about a poetic form of estampie through the discussion of Douce 308. In a chapter titled "The Estampies of Douce 308" from Leach's book
Music and Instruments of the Middle Ages, there is a heavy discussion about how the poetic forms of estampies differ from both instrumental and vocal forms. These poetic estampies were devoid of musical notation making the form reliant on syllabic stress and enjambment to make it recognizable. == History ==
