The Theory of Musical Contours was initially developed by Robert Morris, Elizabeth Marvin and Michael Friedmann as a support for the study of musical contours. Since the 1980s, dozens of authors have used it as a basis for their studies. In Brazil, this theory has been used both as a support for Analysis and for Musical Composition. In this work we present the approaches, applications of this theory in studies carried out in Brazil and its peculiarities. We identified the role of postgraduate students in the use of this theory and the tendency to apply it in the area of Musical Composition.
