I’ll be reading this blog with relish! I just finished working my way through all five volumes in preparation for my comprehensive exams. I definitely felt like I had scaled a tremendous summit when I finished the last page! Good luck to you!
I wish this blog had existed when I was slogging my way through the Taruskin! Best of luck to both of you; I hope you find it as rewarding as I did.
One tip: it helps a lot as far as retention goes if you study the rep. as you go through the books. Sometimes I feel that as musicologists we draw too sharp of a distinction between “repertoire time” and “narrative time.”
