Beschreibung:
Discusses orchestration as a substantial, not accidental factor in musical structure (whereas the latter is the common opinion especially as regards music from before 1750). Usually instrumentation and orchestration in the late Baroque era have been thought to depend on other factors such as semantics (in vocal music) or varying local performance conditions. In fact, Bach's use of instruments, while not strictly autonomous, is based on independent choice, as an analysis of diverse works, e.g., Bach's arrangements of his own works and the Brandenburg concertos, makes clear.
