The Mensural Scoring-up Tool

Vocal polyphonic music from 1280 to 1600 is written in mensural notation and it is typically presented in a layout with separate parts. In this paper, we introduce the Mensural Scoring-up Tool, a set of scripts designed to automatically transform the separate-parts representation of the music into a score by dealing with the context-dependent nature of the notation through the implementation of the principles of imperfection and alteration, outlined by Franco of Cologne (ca. 1280). This tool exhibits 97% accuracy in a corpus of fourteenth- and fifteenth-century pieces, including both black and white mensural notation. The new encoding generated by the Scoring-up Tool could be useful for digital libraries that have digitized their collections of mensural music documents since the symbolic score could accompany the digital images providing a representation that makes the music accessible to a larger audience—since these symbolic scores can easily allow for a conversion into modern values and for playback—and that facilitates music analysis for the experts.
