A computer-implemented score displaying method performed on an apparatus, the apparatus including a display and an input portion, the method comprising: extracting a first plurality of consecutive areas starting from an extraction start point, from among a score being sectioned into areas based on a timeline of the score; displaying the first plurality of areas of the score extracted by the extracting on the display along the timeline of the score; executing, in response to a turn-over instruction on one area among the first plurality of areas of the score displayed on the display via the input portion, a process including: shifting the extraction start point by one area to a forward direction or a backward direction along the timeline of the score; extracting a second plurality of consecutive areas of the score starting from the shifted extraction start point; and displaying the extracted second plurality of consecutive areas on the display, characterized in that, in order to display the extracted second plurality of consecutive areas, when the extraction start point is shifted to the forward direction, the first plurality of consecutive areas except the, along the timeline, backmost area thereof are gradually moved on the display in the backward direction, such that the backmost area of the first plurality of consecutive areas hides behind the backmost area of the second plurality of consecutive areas and newly displaying the, along the timeline, foremost area of the second plurality of consecutive areas at the display position where the foremost area of the first plurality of consecutive areas was arranged before shifting the extraction start point, and, when the extraction start point is shifted to the backward direction, the first plurality of consecutive areas except the, along the timeline, foremost area thereof are gradually moved on the display in the forward direction, such that the foremost area of the first plurality of consecutive areas hides behind the foremost area of the second plurality of consecutive areas and newly displaying the, along the timeline, backmost area of the second plurality of consecutive areas at the display position where the backmost area of the first plurality of consecutive areas was arranged before shifting the extraction start point. extracting a first plurality of consecutive areas starting from an extraction start point, from among a score being sectioned into areas based on a timeline of the score; displaying the first plurality of areas of the score extracted by the extracting on the display along the timeline of the score; executing, in response to a turn-over instruction on one area among the first plurality of areas of the score displayed on the display via the input portion, a process including: shifting the extraction start point by one area to a forward direction or a backward direction along the timeline of the score; extracting a second plurality of consecutive areas of the score starting from the shifted extraction start point; and displaying the extracted second plurality of consecutive areas on the display, shifting the extraction start point by one area to a forward direction or a backward direction along the timeline of the score; extracting a second plurality of consecutive areas of the score starting from the shifted extraction start point; and displaying the extracted second plurality of consecutive areas on the display, characterized in that, in order to display the extracted second plurality of consecutive areas, when the extraction start point is shifted to the forward direction, the first plurality of consecutive areas except the, along the timeline, backmost area thereof are gradually moved on the display in the backward direction, such that the backmost area of the first plurality of consecutive areas hides behind the backmost area of the second plurality of consecutive areas and newly displaying the, along the timeline, foremost area of the second plurality of consecutive areas at the display position where the foremost area of the first plurality of consecutive areas was arranged before shifting the extraction start point, and, when the extraction start point is shifted to the backward direction, the first plurality of consecutive areas except the, along the timeline, foremost area thereof are gradually moved on the display in the forward direction, such that the foremost area of the first plurality of consecutive areas hides behind the foremost area of the second plurality of consecutive areas and newly displaying the, along the timeline, backmost area of the second plurality of consecutive areas at the display position where the backmost area of the first plurality of consecutive areas was arranged before shifting the extraction start point.
