In arrangement, anticipation is a technique of melodic or rhythmic alteration which changes a note that occurs on the beat to be played early resulting in syncopation – so, basically, a controlled 'rushed' or anticipated note or beat. The most common anticipations occur one-half beat early (an eighth note anticipation), a quarter-of-a-beat early (a sixteenth note anticipation), or one-third of a beat early (a triplet anticipation). When the anticipation occurs in the melody, it is a melodic anticipation. Anticipations are sometimes also called pushed notes, pushed beats, or simply pushes.
