A system of graphs is used to facilitate a study of the relationship between a motet and a Mass that is based on it using sixteenth-century parody technique. In the graphs, relationships not immediately apparent from looking at the score become clear, such as the borrowing of the entire complex of a motive and the points of imitation that accompany it, or the relationships among points of imitation that enable them to be combined contrapuntally in a particular manner. The motet Salvum me fac by Jacquet of Mantua and the parody Mass of the motet by Palestrina serve as examples in the graphing process.
