Digital Musicology is a vibrant and quickly growing discipline that addresses traditional and novel music-related research questions with digital and computational means (Honing, 2006;Huron, 1999;Urberg, 2017). Research questions and methods often overlap with or draw on those from diverse disciplines such as music theory and analysis, composition history, mathematics, cognitive psychology, linguistics, anthropology, or computer science (Volk & Honingh, 2012;Wiggins, 2012). Corpus research, i.e., the computational study of representative collections of texts (in the case of linguistics) or notated music (in musicology), plays a prominent role in this trans-disciplinary quest to "make sense of music" through scientific models (London, 2013;Moss, 2019;Shanahan, 2022). ms3 makes scores (symbolic representations of music) operational for computational approaches by representing their contents as sets of tabular files.
