Repeating a motif four times has a reason, such as arriving with more determination to a point, thus increasing the drama. That is why the student has to identify the structure and decide how far she goes, how to prepare, which notes should be emphasized, and what is the harmonic sense of what is being played. It is not enough to play bar to bar. It is necessary to study the piece in detail. It is also interesting to project the sound to the audience to get their attention.
