Syncopation is a vital characteristic of the rhythms of many different types of music from around the world -- pop, jazz, African, Carribean, Latin American...
If you clicked Move left just once on this group, what you should now hear is a syncopated rhythm. Before you moved those notes, all the notes in this rhythm were 'on the beat'. Syncopation is basically playing 'off the beat'.
See if you can hear the different expressive feel that the syncopation creates in the music: the syncopated rhythm has quite a different sound, or feel, from the non-syncopated one.
