• Over the last few years, OMR has been developed and studied. New perspectives have been provided that include handwritten music. Nonetheless, most of the research produced focuses on neumatic, mensural and cultured music. Barely any examples of non-canonical and modern music can be found. This paper is a statement of intention of a larger research project, which will end in the presentation of a thesis. This thesis project provides an idea of how to include a musical genre such as Jazz in OMR studies, until now rejected, by adapting existing tools and procedures, and by examining the ways to carry it out and what the best approaches are. It will result in not only plain transcription but also in the analysis offered by a music that has not been studied in this way and so intensively.
