Our October program was a double feature. On Sunday, October 09, Tacoma AGO members heard Jonathan Ryan perform Bach’s Clavier-Übung III as part of the Richard D. Moe organ recital series at Pacific Lutheran University. Then, on Monday, Mr. Ryan spoke on the Clavier-Übung as the program of our October meeting in Kilworth Chapel at the University of Puget Sound.
The program was in two parts, the first being a discussion of the four parts of Bach’s Clavier-Übung, setting the historical context with references to contemporary documents and musical examples. Mr. Ryan presented musical arguments to support the theory that the Clavier-Übung part III meets the definition of an organ mass.
The second part of the program focused on performance practice, including tempo, registration, and ornamentation. Mr. Ryan made a point that Bach ‘s use of registration was unusual and controversial in his time, and presented historical references to support unconventional registration.
