0:39 What’s your background? 1:41 What was the state of research in the history of music theory when you began? 2:52 How did you come to focus on Thoroughbass in your research? 4:30 What was the perception of Thoroughbass in the 70s-90s? 5:36 The different schools of Thoroughbass 7:01 What key differences are there among the French, German or Italian Thoroughbass traditions? 8:57 JS Bach and his views on Thoroughbass’ importance 10:17 When Thoroughbass first appeared on the scene, was the initial criticism of it justified? 12:40 Did Thoroughbass having nothing to say about melody like Mattheson says? 13:44 How should we view Rameau beyond his cartoonish image as the Fundamental Bass guy? 15:49 Did he separate his scientific, theoretical views on music with his practical side? 17:59 Rameau’s pedagogical heuristic to help students simply the total mass of chords into fundamental types 20:03 Fundamental chords being slower to mental analyze than simply reading from the given bass 21:27 Rameau’s practical nature as a musician 22:32 Why were CPE Bach and Kirnberger so hostile to Rameau? 24:56 Did chord invertibility originate with Rameau or earlier? 27:03 Was the rise of lots of new harmonies and chords naturally yield to a need to categorize chords into fundamental types? 29:20 Did Rameau speak of counterpoint in his treatises? 31:17 Rameau trying to reconcile his theories with the Rule of the Octave 33:07 The chord on the 6th scale degree connecting to the 7th scale degree being a problem for Rameau 34:15 Rameau’s influence in Italy 35:44 Were Rameau’s theories appealing because they were considered more scientific than counterpoint? 38:20 Why did you select François-Joseph Fetis as a subject of study? 40:24 Did Fetis teach according to Catel’s methods? 42:13 Fetis vs Berlioz 43:56 Did they have valid opinions in their dispute? 46:31 Fetis’ influence on later theorists and his key contributions 49:02 Some people say thinking in terms of Roman Numerals is vertically oriented but isn’t Thoroughbass practice the same? 51:07 Are Rimsky-Korsakov and Schoenberg correct when they say that the study of Thoroughbass is no longer needed? 53:37 Did Nadia Boulanger bring out modern tonality despite teaching older methods like partimenti and thoroughbass? 55:28 What do you think of your important research being influential for future partimento and thoroughbass enthusiasts? 59:10 Can we apply Thoroughbass to music like jazz and popular music without any issue? 1:01:13 On Letters and Chord Symbols being harder to calculate vs reading figures 1:04:39 What’s the best way to learn Thoroughbass? 1:06:05 Are there any Thoroughbass treatises that you recommend? 1:08:43 Wrapping Up
