What Comes Next?

This chapter discusses the notion of musical expectancy. Musical expectancy is defined as a process whereby an emotion is aroused in a listener because a specific feature of the music violates, delays, or confirms the listener's expectations about the continuation of the music. Every time the listener hears a piece of music, he or she has such expectations, based on music he or she has heard before. For example, the sequential progression of E-F# may set up the expectation that the music will continue with G#. In other words, some notes seem to imply other notes; and if these musical implications are not realized — if the listener's expectations are thwarted — an affective response might be induced.
