CW,
In the simplest response, rhetoric and affect (affekt) is part of all
of Bach's music. The rhetorical compositional style is the composition
process for Bach's music (and the Baroque style, in general). Affect
is the overall character of a movement or even larger work (suite).
ie. love/hate, joy/anger, hope/doubt. In a practical playing sense,
understanding the dual function of a melodic leap that came about in
the rhetorical style is important to interpreting Bach's unaccompanied
string music. Recognizing when a leap is rhetorical, an expressive
musical gesture, or implying that a new part is entering (implied
polyphony). This function really makes Bach's unaccompanied string
music, self accompanied.
