TECHNICAL FIELD OF THE INVENTION
The present invention relates to a musical score display device that displays a musical score including a key signature and a plurality of musical notes on a display, and a computer-readable musical score display program.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, this type of apparatus uses key data representing key signatures and music data including a plurality of note data respectively representing a plurality of notes, and uses key data on a five-line staff displayed on a display in accordance with a musical notation. Issue and multiple notes are displayed.
[0003]
[Problems to be solved by the invention]
However, in the above-mentioned prior art, a person who is not proficient in music, when viewing a musical score (for example, when playing an instrument while watching the musical score), needs to raise or lower the semitone specified by the key signature. There was a problem that it was difficult to look at everything carefully.
[0004]
Summary of the Invention
The present invention has been made to address the above problems, and has as its object to provide a score display device and a computer-readable score display program that make it easy for even a person who is not familiar with music to view a score. Is to do.
[0005]
In order to achieve the object of the present invention, the feature of the present invention is that a key signature and a plurality of notes are generated based on music data including key data representing a key signature and a plurality of note data respectively representing a plurality of notes. In a musical score display device or a computer-readable musical score display program for displaying musical scores including a musical score on a display, semitones should be raised by a semitone based on key signature data and multiple note data from a plurality of notes represented by a plurality of note data. The present invention is configured to sort a note or a note to be lowered by one semitone, and to control the display so as to separately display a note to be raised by one semitone or a note to be lowered by one semitone in a display mode different from other notes. . In this note separation display, for example, the display color or shade of display of the note to be separated is different from other notes, or only the note to be separated is displayed by adding a special mark such as an arrow, It is preferable to add the accidentals “#” and “♭” to only the notes that are displayed separately.
[0006]
According to this, the note to be raised by one semitone or the note to be lowered by one semitone is displayed separately in a display mode different from other notes, so that the user can read notes one by one without being conscious of the key signature, You can correctly recognize the notes written on the score. When playing a musical instrument while looking at a musical score, it is easy to perform with a correct tonality.
[0007]
Further, another feature of the present invention is that, in the score display device or the score display program, when the notes are displayed separately, the key signature represented by the key signature data is displayed when the notes are not displayed separately. The display is controlled to display in a display mode different from the display mode.
[0008]
According to this, it is possible to easily discriminate between when the note is displayed separately and when it is not. In addition, even when the accidental symbols “#” and “♭” are used as distinction display of notes as described above, since the key signature is displayed in a predetermined display mode, the user has no relation to the distinction display of notes. Can be distinguished from the accidentals "#" and "@" displayed on the score in accordance with the original music notation notation, from the accidentals "#" and "@" added to the notes for separate display of the notes.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an electronic apparatus to which a score display apparatus and a score display program according to the present invention are applied. As the electronic device, various devices including an electronic musical instrument, a sequencer, a personal computer, and the like can be considered.
[0010]
The electronic device includes an input operation unit 10, a display 20, and a sound source circuit 30. The input operation unit 10 is for inputting a user's instruction, and includes a plurality of operators operated by the user, and a detection circuit that detects operations of the plurality of operators and is connected to the bus 40. . The display 20 is composed of a liquid crystal display, a cathode ray tube device, or the like, and displays various characters, codes, figures, and the like, including musical scores, in particular. The display mode of the display 20 is controlled by the display control unit 21 connected to the bus 40. The tone generator 30 generates a tone signal in accordance with performance data and other control data input via the bus 40 and supplies the tone signal to the sound system 31. The sound system 31 includes an amplifier, a speaker, and the like, and emits a tone corresponding to the supplied tone signal.
[0011]
The CPU 51, the ROM 52, the RAM 53, the external storage device 60, and the communication interface circuit 70 are also connected to the bus 40. The CPU 51, the ROM 52, and the RAM 53 constitute a microcomputer main body, and control various operations of the electronic device by executing programs.
[0012]
The external storage device 60 includes an external recording medium such as a hard disk HD pre-installed in the electronic device, a flexible disk FD detachable from the electronic device, and a compact disk CD. The external storage device 60 also includes a drive unit that writes and reads data and programs to and from the external recording medium. In particular, in the present embodiment, the music score display program and the music data (automatic performance data) of FIG. 2 are stored in an external recording medium such as the hard disk HD, the flexible disk FD, and the compact disk CD. The song data includes key data representing key signatures, pitch data representing pitches, note length data representing note lengths, rest data representing rests, etc., in accordance with the progress of the song. And display control data for displaying a musical score. The musical score data composed of key signature data, pitch data, note length data, rest data, and the like generally conform to the MIDI standard. However, in the present invention, various types of devices may be used without complying with the MIDI standard. It is also possible to use a specially defined data format.
[0013]
The communication interface circuit 70 is connectable to a nearby external device 71 by cable or wirelessly, and is also connectable to a remote external device 73 via a telephone line, a dedicated line, a communication network 72, or the like. . The communication interface circuit 70 can exchange various programs and various data including the musical score display program and music data by communicating with the external devices 71 and 73.
[0014]
Next, the operation of the embodiment configured as described above will be described. The user executes a program (not shown) and selects music data to be displayed on the display 20 or music data to be edited by operating the input operation unit 10. In this case, usually, the corresponding music data is selected from a plurality of music data stored in the external recording medium of the external storage device 60, read out, and stored in the RAM 53. Alternatively, the music data stored in the external devices 71 and 73 may be downloaded via the communication interface circuit 70.
[0015]
Then, when the user instructs the musical score display by operating the input operation unit 10, or when the music data is changed during the editing work of the user, the CPU 51 starts the execution of the musical score display program of FIG. 2 in step S10. . The musical score display program is usually stored in an external recording medium of the external storage device 60, and is transferred to the RAM 53 when the musical score display program is first executed, and its execution is started. If the score display program is not recorded on the external recording medium, the score display program can be downloaded from the external devices 71 and 73 via the communication interface circuit 70.
[0016]
After the execution of the music score display program, the CPU 51 initializes the display control data if the music data (including the music score data and the display control data) loaded into the RAM 53 is new or has just been read in step S12. I do. In other cases, this initialization process is not performed. Also, with regard to music data for which display control data (that is, display control data area) is not prepared, display control data is prepared corresponding to the musical score data by the process of step S12. The display control data includes note display control data and key signature display control data.
[0017]
The note display control data is provided corresponding to each of a plurality of note data 1 to N in the musical score data. The note display control data indicates whether each note corresponds to a note to be displayed separately (a note that is raised or lowered by a semitone), and When displayed, the display mode is indicated. The note display control data may be provided separately from the note data as shown in FIG. 3A, or may be included in each note data as shown in FIG. 3B. It may be. In FIGS. 3A and 3B, each note display control data represents a note that does not need to be separately displayed by “none”, and the note to be displayed separately is displayed in a separated display mode (in this case, a semitone). ("#"), Which indicates raising. Note that the pitch in the note data of FIG. 3B indicates the note name of the note, and the time indicates the time position where the note appears (eg, the absolute time from the beginning of the song or the beginning of the bar). , The length indicates the note length of the note concerned.
[0018]
The key signature display control data is provided corresponding to each of a plurality of key signature data 1 to M in the musical score data, and each key signature is displayed in a normal display mode or a special display mode. , And when displayed in a special display mode, indicates the display mode. The key signature display control data may also be provided separately from the key signature data as shown in FIG. 4A, or may be provided in each key signature data as shown in FIG. It may be included. In FIGS. 4A and 4B, each key signature display control data indicates that the key signature is normally displayed by “normal”, and the key signature displayed in a special display mode is displayed. (In this case, a special display mode in which the color (including light and shade) is different from other displays). The key in the key data shown in FIG. 4B indicates the key name, and the start time and the end time indicate the start position and the end position of the effective range of the key by the key data in absolute time from the beginning of the music. Is shown.
[0019]
Returning to the description of FIG. 2, in the initial setting of the step S12, all the note display control data are set to “not separately displayed”, and all key signature display control data are set to “normal display”. Set. Next, in step S14, it is determined whether or not the display mode is the sorted display mode, that is, whether or not the execution of the musical score display program has been started in a state where the sorted display of the musical notes is selected.
[0020]
First, a case will be described in which the execution of the musical score display program is started in a state where the user does not select the note separation display. In this case, "No" is determined in step S14, and all the key signature display control data are set to "normal display" and all the note display control data are set to "normal display" by the processing of steps 16 and S18. Do not display separately ". Since the processing of steps S16 and S18 is included in the initialization processing of step S12, when the initialization processing is executed, it is not necessary to execute the processing of steps S16 and S18. .
[0021]
After the processing in steps S16 and S18, the CPU 51 generates score display control data based on the score data and the display control data in step S40, outputs the generated score display control data to the display control unit 21, and in step S50, executes the process of the score display program. Terminate execution. The display control unit 21 controls the display 20 according to the score display control data, and displays the score on the display 20. In this case, all key signature display control data indicates "normal display", and all note display control data indicates "no separate display". The score is displayed according to standard notation as shown in FIG. In this case, everything including the five lines, the key signature, and the musical note is displayed in black.
[0022]
Next, a case where the execution of the musical score display program is started in a state where the user has selected the separated display of notes by operating the input operation unit 10 will be described. In this case, it is determined as "Yes" in step S14, and when the musical score data is sequentially read from the beginning and the key signature data is read, the dashed-dotted line is displayed for the valid section of the key signature represented by the key data. Execute the processing in the frame. That is, in step S20, the key signature display control data corresponding to the read key data is set to a data value indicating that the key represented by the key data is displayed in an unusual special display mode. . In this case, the key control display control data is set to a data value for displaying the key in gray, which is a color lighter than black in the normal display mode.
[0023]
After the process of step S20, note data belonging to the valid section of the key signature is cut out in step S22, and the process of steps S30 to S38 is performed on each of the cut note data (in the two-dot chain line frame in FIG. 2). Is performed). In these processes, each note is a note to be raised by one semitone, a note to be lowered by one semitone, or a raise or lower of a semitone by comparing the key data representing the key signature and the note data respectively representing each note. It is determined whether or not the note is unnecessary, and according to the determination result, the note display control data corresponding to each note is changed to a data value representing “semitone up,” “semitone down,” and “do not display separately.” Each is set.
[0024]
Specifically, if it is a note to be raised by one semitone, "Yes" is determined in step S30, and the display control data for the note is changed to a data value (in this case, the temporary symbol "#"). If it is a note to be lowered by one semitone, "Yes" is determined in step S32, and in step S36, the note display control data is changed to a data value representing "lower semitone" (in this case, a data representing an accidental symbol "@" Value). If the note does not require raising or lowering the semitone, both are determined to be "No" in steps S30 and S32, and in step S38, the note display control data is set to a data value representing "do not separately display".
[0025]
When the processing for all the notes in the section where one key signature is valid is completed in this way, the CPU 51 reads the next key data and executes the processing of the above steps S20 to S38. When the processes in steps S20 to S38 are completed for all key signatures, in step S40, the display 20 is controlled via the display control unit 21 in the same manner as described above, and the score is displayed on the display 20. indicate.
[0026]
In this case, since the note display control data relating to the note to be raised by one semitone is set to a data value representing the accidental sign "#", the left side of the corresponding note on the musical score, as shown in FIG. , An accidental symbol “#” is displayed. Since the note display control data relating to the note to be lowered by one semitone is set to a data value representing the accidental symbol "♭", the musical note is displayed with the accidental symbol "♭" added to the left side of the corresponding note. The accidentals "#" and "@" for discriminative display of these notes are displayed in black. Since the note display control data relating to notes that do not require raising or lowering a semitone is set to a data value representing “do not display separately”, the corresponding note on the musical score has, as shown in FIG. Only notes are displayed without the addition of accidentals "#" and "@". Also, the key signature display control data relating to the key signature is set to a data value representing a gray color, so that the key signature is displayed in five lines, musical notes, and other display colors (black) as shown in FIG. It is displayed in a different gray color from.
[0027]
As can be understood from the above description of operation, according to the above embodiment, the note to be raised by one semitone or the note to be lowered by one semitone is displayed separately in a display mode different from other notes. Just by reading one by one, the notes written on the score can be correctly recognized. When playing a musical instrument while looking at a musical score, it is easy to perform with a correct tonality. If the user wants to display the score on the display device 20 without specifying the sorted display mode, the process of the above-described steps S14 to S18 causes the display of the score based on the original music data in accordance with the original notation. You can easily put it back. This is because, in the above embodiment, even when notes are displayed separately, the score data is maintained without being changed, and the notes are displayed separately only by changing the display control data.
[0028]
Also, in the above embodiment, the key signature when the notes are displayed separately is displayed in a display mode different from that when the notes are not displayed separately, so that when the notes are displayed separately. , When it is not, you can easily distinguish. In addition, since the key signature is displayed even when the notes are displayed separately, the user can use the accidental symbol “#” displayed on the score according to the original music notation irrespective of the separated display of the notes. , “♭” can be distinguished from accidentals “#” and “♭” added to the note for discriminative display of the note. In addition, the key signature when the musical notes are displayed separately is made inconspicuous gray, as in the above-described embodiment, so that the key is not disturbed when the score is viewed.
[0029]
As mentioned above, although one Embodiment of this invention was described, in implementing this invention, it is not limited to the said Embodiment, A various deformation | transformation is possible unless it deviates from the objective of this invention.
[0030]
For example, in the above-described embodiment, the notes to be raised or lowered by a semitone are displayed separately using the accidentals “#” and “♭”. However, instead of this, the note to be raised and lowered by a semitone may be distinguished from the other notes by making the display color different. For example, as shown in FIG. 5C, a note to be raised by one semitone is displayed in red, a note to be lowered by one semitone is displayed in blue, and other notes are displayed in a color different from red and blue, such as black. Good. In addition to special symbols and color coding, notes can also be sorted and displayed in various ways, such as by adding and displaying special symbols (for example, arrows and triangle marks). Further, regarding the position where the symbol is added, it is also possible to add the symbol at an appropriate position different for each note in consideration of, for example, the space at the top, bottom, right or display, in addition to the left side.
[0031]
In the above embodiment, when notes are displayed separately, the tone of the key signature is made different from when notes are not displayed separately and other display contents. However, instead of this, various changes are possible, such as changing the color of the key signature. The display of the key signature and the distinction display of the musical notes may be made different depending on the type of the key signature.
[0032]
In the above embodiment, each time the musical score display program is executed, the musical note display control data and the key signature display control data of the entire music piece are reviewed. However, instead of this, note display control data and key signature display control data may be reviewed only for a portion (difference) that has changed from the previous music data. Alternatively, the change status of the music data may be checked at intervals of a relatively long time, and the musical note display control data and the key signature display control data may be reviewed only for the changed portion (difference). According to this, the processing load of the score display program can be reduced, and this is particularly effective when the score display program is executed at the time of editing music data.
[0033]
Furthermore, in the above-described embodiment, when the user selects to display notes separately, the notes are displayed separately for the music data of all key signatures. However, instead of this, the type of the key signature in which the notes are displayed separately is predetermined by the user and stored, or the user can appropriately select the key signature, and the key signature is displayed separately from the key signature in which the notes are displayed separately. The key signature that is not displayed may be distinguished by the user.
