Musical Expectancy

• Questions about the process of expectancy generation and realization

• The factors underlying the formation of musical expectations. What processes give rise to the formation of expectancies, and influence the content of these expectations

• The subsequent implications of expectancy realization on musical processing, including basic responses to music, guiding of attention, memory for music, and so on.

The Implication-Realization Model

(Narmour, 1990, 1992)

• Registral Direction – small intervals imply melodic continuation in the same direction, whereas large intervals imply a reversal of direction

• Intervallic difference – small intervals imply similarly sized intervals whereas large intervals imply smaller intervals

• Registral Return – refers to cases in which the second tone of a realized interval reverse pitch direction, thus producing approximate symmetry in patterns

• Proximity – there is a general preference for small realized intervals

• Closure – closure occurs when a melody changes direction or when a relatively smaller realized interval follows a larger implicative interval
