PROBLEM TO BE SOLVED: To allow a performance reproduction device to visually display to sound of performance a state of the performance of an instrument such as which finger strikes which key, fingering, and its form. SOLUTION: MIDI(musical instrument digital interface) data of a melody and the corresponding fingering data are prepared. Motion data for plotting expression of performance motions of an instrument are stored in a motion data storage part 4 for each motion pattern of performance motions beforehand, and a motion determination part 15 determines a motion pattern for each sound from the MIDI data and fingering data, and a motion data reading part 17 reads the corresponding motion data. Plotting is performed by computer graphics at a plotting engine part 3 by using this motion data. On the other hand, the MIDI data are delayed by a specified time at a data delaying part 18, and are then converted into speech signal through an speech engine part 2 as a sound source. |
