Discussion of Alfred Hitchcock's use of music as a plot device, particularly in the 1956 version of The Man Who Knew Too Much, where each of the musical selections serves as commentary in addition to serving the plot. For more in depth analysis of the lyrics to the Storm Cloud Cantata, the Portents Hymn, and Whatever Will Be, see the forthcoming new edition of WRITING WITH HITCHCOCK.
