Claim Text:
1. An apparatus, comprising: a storage configured to store score data indicating a musical score of a musical performance, the stored score data including full score data and N part score data items stored separately from the full score data, the full score data being a union of the N part score data items that lacks information that separates the N part score data items from each other, wherein N is a natural number greater than 1, and an N-th part score data item among the N part score data items includes a first note having a length of time that differs from the length of time of the first note in the full score data and a second note having a generation time that differs from the generation time of the second note in the full score data, a display device configured to display an image of a full score indicated by the full score data; and computer-executable instructions including instructions, that when executed by a computer, cause the apparatus to: select codomain data items of the N part score data items included in the full score data; and estimate mappings, which correlate time positions of the data in the full score data with time positions of the data in part score data items among the N part score data items, having a maximum probability that data items, obtained by applying the mappings to the N part score data items as domains, will be codomain data items of N parts, thereby identifying the N part score data items in the full score data such that when the second note in the full score data is indicated in a state that the image of the full score is being displayed by the display device, the apparatus is caused to transmit, to an external apparatus, information indicating the second note of the N-th part score data item corresponding to the second note in the full score data.
