Modulated portion displaying apparatus, accidental displaying apparatus, musical score displaying apparatus, and recording medium in which a program for displaying a modulated portion, program for displaying accidentals, and/or program for displaying a musical score is recorded

摘要

A key of each measure is distinguished depending on performance data representing sounds composing a tune. It is judged whether or not the distinguished key coincides with tonality data of the corresponding performance data, whereby it is judged whether or not the performance data is modulated with a key signature omitted. A musical score corresponding to a portion which is not modulated with a key signature omitted is displayed in a normal manner. Meanwhile, a musical score corresponding to a portion which is modulated with a key signature omitted is displayed in a specific displaying manner different from the normal displaying manner, such as in color different from the normal displaying manner, and/or in a reversed displaying manner, whereby a user can confirm the portion which is modulated with a key signature omitted.
