(um, not that kind of BASIC...)
If any of you wish to re-visit or begin your knowledge of basic Gregorian chant, I will have a 30 minute session before Tuesday rehearsals for several weeks. That means you would need to arrive by 6:30 PM. The sessions will run from 6:30 PM - 7 PM. [...]
If you want to do this, please let me know so that I can prepare accordingly. I only need to hear from you if you plan on being present for the short chant session.
