This dataset was created as part of corpus research project in the context of the SIMSSA Project, a SSHRC-Funded Partnership Grant (https://simssa.ca/). Starting with files from the Josquin Research Project, we extracted duos to be able to study two-part counterpoint. The JLSDD (Josquin La Rue Secure Duos Dataset) consists of: 33 secure Josquin duos (Sibelius, Music XML, MIDI, MEI, **kern, and PDF) 44 secure La Rue duos (Sibelius, Music XML, MIDI, MEI, **kern, and PDF) The Sibelius templates used to create the corpus In addition, we have made the following sets available (all discussed in the paper below): Josquin duos (not secure) La Rue duos (not secure) If you use the dataset, please cite the following work: Cumming, Julie E., Cory McKay, Jonathan Stuchbery, and Ichiro Fujinaga. 2018. “Methodologies for Creating Symbolic Corpora of Western Music before 1600.” In Proceedings of the International Society for Music Information Retrieval Conference, 491–98.
