PROBLEM TO BE SOLVED: To enable performance information including correct time values for a triplet to be created even if a group of notes is not described in a musical score.SOLUTION: A musical score performance device comprises: bar specified time calculation means for calculating a bar specified time from a rhythm of music; bar performance time calculation means for calculating a bar performance time from pronunciation timing and time values of notes and rests in a bar; first comparison means for comparing the calculated bar specified time and the bar performance time; and time value correction means for correcting the pronunciation timing and time values of the notes and the rests on the presumption that there is a group of notes in the bar if the bar specified time does not correspond with the bar performance time. The time value correction means changes a time value of a note to be corrected in a bar to two-thirds to perform a note grouping process, and repeatedly performs a process of comparing the bar specified time and the corrected bar performance time with the changed time value, whereby determining a group of notes of a triplet with a changed time value for each note at the time when the bar specified time corresponds with the corrected bar performance time. |
