<P>PROBLEM TO BE SOLVED: To enable intuitive recognition of relation between a music score and a keyboard, and facilitate stepwise learning of an eventual keyboard operation based on the music score. <P>SOLUTION: A CPU performs: generating data of an image of a two-dimensional plane representing a musical tone at a predetermined temporal point and constituted by a first axis of music in its progress direction and a second axis representing the height of pitch, as data of a music-score image, on the basis of musical tone data allowing replaying of a predetermined musical tone; generating data of an image of a two-dimensional plane representing a piano roll at a predetermined temporal point and constituted by a third axis of the music in its progress direction and a fourth axis representing the height of pitch, as data of a piano roll image, on the basis of the musical tone data; and generating, as data of a three-dimensional performance image, data of an image showing a situation of placing the music score image and the piano roll image in a three-dimensional space constituted by a temporal axis, the second axis and the fourth axis, where the temporal axis is constituted by matching the first and third axes. <P>COPYRIGHT: (C)2013,JPO&INPIT |
