How does syncopation disrupt a listener’s expectations?

Syncopation disrupts a listener’s expectations by displacing the regular accents associated with established metrical patterns. By shifting emphasis away from the expected pulse, syncopation creates a sense of instability that arouses a desire for the reestablishment of metric normality.1

This disruption is typically achieved through several techniques:
* Accenting normally weak beats within a measure.12
* Resting on a beat that is normally accented.1
* Tying a note over into the next measure, which obscures the expected rhythmic flow.1

This technique is fundamental to the characteristic "forward drive" found in many musical styles, including jazz and various forms of folk-dance music. By momentarily breaking the predictable rhythm, syncopation engages the listener and creates a dynamic sense of movement.13
