Apparently the prof has given the homework but there is no textbook or material to study yet to go with it. I seem to remember that there is a theory discussion site out there somewhere. Does anyone know about it?Meanwhile - maybe a google search on Counterpoint - analysis, counterpoint - intervals, Do you know the name of the book that hasn't come in yet? Can the prof point you to any resources? Has he given handouts? Your own student notes?
I'd like to know what a cadence was in that period before there were chords. Does anyone know?
