I guess I'll repeat my reply here:I have the book, and while it is an admirable attempt, sometimes the analyses leave a little bit to be desired. The main problem is that it tries to force a bunch of roman numerals on every vertical simultaneity, slice by slice, without regard for the overall context and actual horizontal motion.
[...]In the library of New York´s Juillard School in 2013 I found this excellent Bach book:It has Roman numerial analysis below - and modern JAZZ CHORDS simultaneouslyexactly above the academic numerials in the Bach piano score.[...]There is a twin-book, without analyses, but with lot of spaces to pencil in your own harmonizations, alternative voice-leading, modulations and your own personal chords. Then you can compare your own every day maturing thinking - with Bach.This book has often 4 - 5 different versions of Bach´s own harmonizations for the same hymn melody - so you quickly learn there is no absolute right, just creativity.
Good morning, 8_octaves, and thank you for your activity and your questions:You are right, the books spiral bound and are not used in most libraries.In New York´s Juilliard Scool in 2013 I met the anlyzed book in the Bach project´s handlibrary. I got it as present when the project finished in the Bach studio.Yes, the exercise book was developed later: At least I got my own last year.Important here, is that the author of both books is gentle master Chris Czarnecki, who works from his studio in N.Y. My personal contact with Chris was through his website which is here: https://bachchoraleharmony.com/ Chris is highly gifted as a theorist, but not so practical with self-publishing, he is a gentle, rather shy, scholar.Yes, I feel, that I am promoting the books, as a teacher, they do really work.Perhaps a forum like here, is not the right place, for which I deeply apologize.Friendly greetings from a sunny Stockholm,Marika
