Syncopation [Abbreviations] sync
Displacement of either the normal beat or the normal accent. "Normal" is the regularly recurring groups of 2 or 3 beats, the first of each group being emphasized, as in waltz (123; 123) or foxtrot (1234; 1234). If the listener or dancer feels any irregularity, that is syncopation -- e.g., use of eighth notes or rests, or emphasis on the 2-count, or a foxtrot measure danced QSQ. Most common, it is stepping or acting between two beats of music, on an & count, such as 1, 2/&, 3; (in waltz) or S, -, Q/&, Q; (in foxtrot). Syncopation is any kind of emphasis on a part of the measure not expected to be emphasized.
