Even in such a display screen, the minimum information necessary for visual recognition of the music is always displayed, so that there is almost no trouble in playing while viewing the score.

  Note that the situation in which the additional display data to be additionally displayed on the note overlaps with other display data includes the situation in which the display screen protrudes from or exceeds the frame of the display screen. Further, the additional display data to be additionally displayed on the note is mainly a decoration symbol, but may be, for example, pitch name information, key number, fingering information, or the like. The display position for the note is the adjacent area on the top, bottom, left, and right of the note, and is set according to the type of additional display data. For example, the decoration symbol is “up” and the fingering information is “left”. Further, the type of additional display data to be additionally displayed on the note may be selected and set by the user, or may be determined by default. Furthermore, for example, the type of additional display data to be additionally displayed may be set according to the size of the display screen. When displaying note name information, key number, fingering information, etc. on the score, if the note name information, key number, fingering information, etc. are displayed overlapping notes or other musical symbols The display of the note name information, key number, fingering information, etc. to be performed is omitted. In this case, display importance may be set for each additional display data to be additionally displayed on the note, and priority display may be performed according to the importance.

Next, a flowchart of a score display process executed in the score display apparatus 1 of the present invention is shown in FIG.
The musical score display process shown in FIG. 5 is performed when a musical instrument such as a MIDI keyboard is connected as the external device 15 when an instruction to display a musical score for practicing the musical instrument is given by the input operation unit 16 or when an automatic performance is performed. When it is instructed, the program is activated, and in step S10, any of the music pieces that are stored in the ROM 11 or the external storage device 13 and that is desired to be displayed is selected. In this case, if the music is only performance data in the MIDI format and there is no corresponding score display data, the music is converted into a score display data format based on the performance timing data and performance event data in the performance data. Next, in step S11, the display screen is set such as the resolution of the display screen, the staff type, the number of display columns, the number of display bars per column, and the font size. In step S12, the type of additional display target data (decoration symbol, pitch name information, key number, fingering information, etc.) is selected, and the display position (up / down / right) of the additional display data to be displayed for the note. / Left, etc.), and priorities for displaying additional display data, such as when multiple types of additional display data are displayed at the same display position, are set. In this case, the priority order may be determined by selecting the skill level so that, when practicing a musical instrument, priority is given to the display of decorative symbols at the advanced level, and priority is given to the display of pitch name information at the beginner level. good.

  Further, if there is a change in the display screen setting from the default state in step S11 or a change in the additional display data setting from the default state in step S12, the position assignment of notes changes, etc., so the setting is made in step S13. Make adjustments according to the content. In step S14, a data list to be additionally displayed and a data list not to be additionally displayed are initialized. Since these data lists are stored in a work area secured in the RAM 12, and the data list may be prepared for each type of additional display data, for example, the type name and identification (ID) number of the additional display data. Etc. are recorded. Then, in step S15, displayability determination is performed for each type of additional display data set as a display target, and the type of additional display data determined to be capable of additional display without overlapping is recorded in a data list for additional display. At the same time, the type of additional display data that has been determined not to be additionally displayed without overlapping is recorded in a data list that is not additionally displayed. In step S16, the additional display data is displayed as a score on the display screen in accordance with the score display data other than the type of additional display data recorded in the data list not to be additionally displayed. As described above, by not displaying the additional display data of the type recorded in the data list not to be additionally displayed, it is possible to prevent the additional display data from being displayed overlapping the notes. Further, when a situation occurs in which the display position overlaps in the additional display data of different types recorded in the additional display data list, only one type is displayed according to the importance (priority order), so that a note is displayed. It is possible to prevent the additional display data from being displayed overlapping each other. When the process of step S16 ends, the score display process ends.

  A flowchart of the data list recording process performed in step S15 of the score display process is shown in FIG. When the data list recording process is started, it is determined in step S20 whether or not additional display data of the type currently targeted exists in the score display data. Here, if it is determined that there is additional display data of the target type, the process proceeds to step S21, and in the additional display data of the target type according to the display screen setting information set in step S11. The number of dots in the display area at the display position is calculated. Next, in step S22, it is determined whether or not the additional display data of the target type can be displayed in the display area without overlapping the note. If it is determined that the additional display data of the target type can be displayed without overlapping the note in the display area, the process proceeds to step S23 and the type of additional display data targeted for the data list to be additionally displayed. Record. If it is determined that the additional display data of the target type does not overlap within the display area and cannot be displayed, the process branches to step S24 and the type of the additional display data targeted for the data list not to be additionally displayed is displayed. Record.

In this case, the display area adjacent to the note can be calculated from the size (resolution) of the screen, the number of display stages, the number of display bars per stage, the size of the font, and the like. Depending on the situation, even if the display area adjacent to the note is large, the display area adjacent to the top and bottom of the note may be narrow or vice versa. Furthermore, the situation in which the data to be added to the note is overlapped with other display data includes the situation in which the data sticks out of the frame of the display screen.
By the way, fonts for displaying musical symbols such as musical notes and decoration symbols are prepared, and fingering information and pitch name information are displayed by generally used fonts. Therefore, it is possible to determine whether the display can be performed without overlapping the display area calculated by referring to the target type of font information. Since the number of dots varies depending on the font, the determination as to whether the display can be performed without overlapping in the display area differs depending on the type of the additional display data to be processed.

If it is determined in step S20 that there is no additional display data of the target type in the musical score display data, and if the processing in step S23 or step S24 is completed, the process proceeds to step S25. Thus, it is determined whether or not display possibility determination has been performed for all types of additional display data set as display targets. If it is determined that display of all types of additional display data set as display targets has not been determined, the process returns to step S20, and the display targets remaining in steps S20 to S24 are set. The data list recording process of the type of additional display data is repeated. If it is determined in step S25 that all types of additional display data set as display targets have been displayed, the data list recording process ends and the process returns to step S16.
In the above description, when the additional display data is displayed overlapping with other display data, the additional display data is not displayed. Instead, the font of the additional display data is changed to other display data. It may be displayed in a small font that does not overlap.

  The musical score display process described above is performed for one selected musical piece, and when the musical score display process is completed, the musical score of the selected musical piece is displayed on the display 18. In this case, when one score cannot be displayed on the display screen on which the score is displayed on the display 18, a part of the score is displayed. When a musical instrument connected as the external device 15 is operated to start playing, the musical score displayed according to the tempo of the selected music is scrolled. Therefore, the performer can practice the performance while viewing the score. When the musical instrument is operated, a musical tone based on performance setting information such as timbre information in the music is generated by the sound source 19 at the timing of the musical instrument operation event and emitted from the sound system 20. In the case of automatic performance, the musical score displayed according to the tempo of the selected music is scrolled when the automatic performance is started, and the musical sound based on the performance setting information of the music and the performance information is generated as the music progresses. The sound is generated at 19 and emitted from the sound system 20.

  In the above description, the score display device is provided with a sound source. However, the present invention is not limited to this, and as a score display device having only the function of the score display device, the electronic device is connected to the electronic device including the sound source.
