How can tying a note across a bar line create syncopation?

In music, syncopation is defined as the displacement of regular accents within a metrical pattern, which disrupts a listener's expectations and creates a sense of forward momentum.1

Tying a note across a bar line creates syncopation by effectively shifting the emphasis away from the expected downbeat of the new measure. When a note is held over from the end of one measure into the beginning of the next, the natural accent that would typically occur on the first beat of the new measure is suppressed or delayed. By preventing the expected rhythmic "reset" at the bar line, this technique forces the listener to perceive the accent in an unconventional position, thereby fulfilling the definition of syncopation as a temporary displacement of the regular metrical accent.12
