MODULATION SECTION DISPLAY DEVICE, ACCIDENTAL DISPLAY DEVICE, MODULATION SECTION DISPLAY PROGRAM, AND ACCIDENTAL DISPLAY PROGRAM

摘要

PPROBLEM TO BE SOLVED: To provide a modulation section display device that detects a section which is modulated having key signature notation omitted and indicates it to a user. PSOLUTION: It is judged whether each measure is modulated without a key signature (step SB3) from whether a key signature decision result (step SB2) of the measure decided based upon musical performance data representing respective sounds constituting music matches tonality data in corresponding musical performance data. Then a section which is is not modulated without a key signature is displayed in a normal musical score form (step SB4). A section which is modulated without a key signature is displayed in a special musical score display form in a different display color from the normal display form or in an inverted state (step SB5). Consequently, the section which is modulated having the key signature omitted can be detected and indicated to the user. PCOPYRIGHT: (C)2007,JPO&INPIT
