Williamsangst (Williams + angst) is the terrible feeling that John Williams is suddenly standing behind you as you write, peering over your shoulder snickering and clicking his tongue in disapproval. This is a very real anxiety for many composers. Even John Williams is said to experience this phenomenon from time to time.
Charles Bernstein (Film Music And Everything Else!, 2000)
You can describe something which perhaps isn’t there on the actual screen but which, together with the music, starts to exist. It’s interesting – drawing out something which doesn’t exist in the picture alone or in the music alone. Combining the two, a certain meaning, a certain value, something which also determines a certain atmosphere, suddenly begins to exist.
Krzystof Kieslowski (Kieslowski On Kieslowski, 1993)
