You can’t talk about musical modes in the 19th-20th. c. without mentioning Bourgault-Ducoudray. All things ‘mode’ lead back to him. That’s, at least, what I found out studying the reemergence of modes in Western music. I’ll be presenting on analytical methodologies on Dec 3 2021 (Paris, UTC+1) at the Paris Conservatory. All are welcome in person or on Zoom.
