[Inactive link:] Gregorian Chant Online. [Ongoing throughout year. Check schedule for class offerings and times.] Reading square notes is easy and fun. Start with the basics of the four line staff and simple neumes, and progress quickly toward being able to sing Mass ordinaries and propers, chant hymns, psalmody…the list goes on. More advanced sessions examine the Gregorian modes, theories of plainsong rhythm, and more. Taught by Arlene Oost-Zinner.
