In the case of being described in L, the display form of the “clean text data” is also described by the tag.

A plurality of templates, for example, for adults, children, advanced users, beginners, etc., are prepared in advance as the engraving data. When the user selects a desired one from these templates, The copy data of the variation is supplied. At this time, if none of the prepared variations has a user's preference, a template closest to the user's preference is selected and edited to match the user's preference. Should be supplied.

It should be noted that the transcript data is data conforming to XML because it adds a new tag to the musical score logical data or changes the contents of an existing tag.

Next, layer data is supplied (block 35).

In the present embodiment, a general-purpose viewer (for example, a Web browser) and a dedicated viewer are employed as application software for displaying music information. As described above, music information is converted into a general-purpose language XML.
Therefore, the music score information can be displayed on both viewers. The dedicated viewer is provided with a function for writing on the displayed musical score, and the written content is converted into data described in XML, like the musical score information, and displayed on the same screen as layer data. Is done. That is, the written content described in XML can be displayed on the same screen by combining it with music information as layer data. The block 35 performs a process of supplying layer data in order to combine it with music information.

The information supplied as the layer data includes various contents other than the contents written on the dedicated viewer as described above, and the contents will be described later.

Further, a music style sheet is supplied (block 36). The style sheet is the SGML

FIG. 3 is a block diagram showing a flow of processing for generating music information (contents) from the input general-purpose performance data and general-purpose music data. This drawing is an excerpt of a part of the processing in FIG. 2, and therefore, in FIG. 3, the same blocks as those in FIG. 2 are denoted by the same reference numerals.

In FIG. 3, general-purpose performance data input from block 31 (when general-purpose music data is input from block 32, this general-purpose music data is converted to general-purpose performance data as described above). Is subjected to the processing shown in the flowchart of FIG. 4 by the music score creation engine formed by software (block 51), and the content is generated as described in the block 38 of FIG.

FIG. 4 is a flowchart showing the procedure of the music score information creation processing executed by the music score creation engine of the block 51.

In the figure, first, when performance data in the SMF format, which is general-purpose performance data, is input from the block 31, the input performance data in the SMF format is converted to the R data.
The data is temporarily stored in the performance data storage area of the AM 7 (step S1).

Next, the performance data is analyzed, various judgments are made, and the musical score logical data is generated (step S).
2). Here, the analysis and judgment of the performance data is specifically performed as follows.

That is, (1) the pitch of a note is detected from the note number forming the note on / off event, and (2) the time from the note on event to the note off event corresponding to the note on event is calculated. (3) Detecting the playing style from the detection results of the above (1) and (2).

Each of these analysis / judgment techniques is a known technique, and the present invention has no characteristic in the point of the analysis / judgment technique, and is based on the result analyzed and judged in this way. As described above, the feature is that score logical data described in XML is automatically generated.

The musical score logical data generated in this way is branched into two, one proceeds to the processing of step S3, and the other proceeds to the processing of step S4. Since the processes in steps S3 and S4 do not proceed at the same time,
For example, two modes, a mode for shifting to the process of step S3 and a mode for shifting to the process of step S4, are set.
The process may be shifted to any one of the processes according to the user's instruction.

In step S3, the formatted musical score logical data is generated by adding the engraved data supplied in the block 35 to the generated musical score logical data. Here, the engraved data is not pure data, but a filter program provided with various templates (encoded data). By passing the generated musical score logical data through this filter program, the score A new tag is added to the logical data or an existing tag is deformed to generate shaped musical score logical data.

On the other hand, in step S4, link information between the generated musical score logical data and the input performance data in the SMF format is generated. Specifically, as described above,
An ID is assigned to each note-on event of the performance data to make each note-on event a meta-event, and an ID is also assigned to each note-on data (tag) of the generated musical score logical data. Thereby, each note-on event of the performance data and each note-on data of the musical score logical data are associated one-to-one, and thereafter, in synchronization with the music information as the content, an automatic performance by the performance data is performed, It is possible to instruct the start position of the automatic performance based on the performance data from the music side, and to turn over or scroll the displayed music score in accordance with the performance data.

When playing back performance data including a note-on event as a meta-event by a sequencer,
Since the sequencer usually ignores the metadata and regards it as a normal note-on event to which no metadata has been added, no problem occurs.

In the present embodiment, the SMF-format performance data has been described as an example of the input general-purpose performance data based on which the musical score logical data is generated. However, when performance data in another format is input. Uses this performance data as SM
By formatting in the F format, the above processing can be applied as it is.

Further, when performance data in a format other than the SMF format is input as general-purpose performance data, an analysis / judgment method suitable for the format can be selected so that a format other than the SMF format can be selected. The above-described processing can be applied as it is (or without significant change) without converting the performance data to the performance data in the SMF format.

Further, the generated musical score logical data includes
Since all information of the performance data is described as tags,
The original performance data can be easily restored from the musical score logical data. Accordingly, when the musical score logical data is generated from the musical performance data in a format other than the SMF format as described above, the musical performance logical data can easily generate the SMF format performance data.

FIG. 5 is a block diagram showing the flow of processing for displaying music score information from the generated musical score logical data, the supplied sanitized data and the style sheet. The figure shows
Since a part of the process of FIG. 2 is extracted, FIG.
The same blocks as those in FIG. 2 are denoted by the same reference numerals.

As described above, the score logical data generated in the block 33 is shaped by the engraving data supplied in the block 34, and the shaped score logical data is
It is supplied to block 61. Further, a music style sheet is supplied from the block 36 to the block 61.

In block 61, first, the formatted musical score logical data is converted by a converter template called a style sheet.
The data is converted into data described in VML by a function of a ctormarkup language) and displayed as vector graphics data. Here, the VML is one of the standard drafts of a format for displaying vector graphics on the Web. The advantages of this language are that it is a standard, so it is widely supported, and that it is a vector system, so that the image quality does not degrade even when enlarged / reduced display is performed.

The style sheet is like a template for associating each tag in the formatted musical score logical data with a music symbol or music font as drawing information (graphic information).

The style sheet of this embodiment is a style sheet for music, and has a plurality of variations as described above. For example, two types of style sheets for advanced users and beginners are prepared. In the advanced style sheet, if the formatted musical score data is in the form of a trill, it is converted into a trill symbol, while the music score data is converted into a trill symbol. In the style sheet, the music data is converted into music information that is easy to play with actual notes and with a smaller number of actual trills.

FIG. 6 is a diagram showing a display example in which the formatted musical score logical data and the music style sheet are actually displayed on a Web browser.

FIG. 7 is a diagram showing musical score logical data 2 in XML.
It is a figure which shows the description method of a kind, (a) has shown the description method according to a part, (b) has shown the description method according to a bar. The part-by-part description method shown in FIG. 2A describes the score of a certain part from the first bar to the end bar, and then describes another part similarly from the first bar to the end bar. This is repeated for all parts.

The description method for each bar in FIG. 11B describes all parts in the first measure, and then describes all parts in the second measure. This is repeated until the end bar.

As described above, an ID is assigned to each note-on event in the performance data, and information corresponding to the ID is also assigned to each note-on data in the musical score logical data. However, when performing an automatic performance based on performance data, the following various processes can be performed.

That is, (1) a process of changing a musical note of a musical score displayed in synchronization with performance data during an automatic performance from a normal display (changing a color or blinking the musical score); URL is written at the position where the information corresponding to the ID is described, and the URL is accessed in synchronization with the performance. (3) When the score is divided into a plurality of pages and displayed, The process of automatically turning the music score by comparing the event ID of the event with the note ID of the music score being displayed. (4) The process of displaying a specific part in a different color according to the performance. It can be carried out.

FIG. 8 is a flowchart showing the procedure of each of the processes (1) to (3) of the above (1) to (4).

In the figure, first, a note-on event is read from the performance data after a lapse of time indicated by the time information (step S11).

Next, it is determined whether or not the read note-on event is an ID meta-event (step S12).
If it is a normal note-on event to which D is not added, the note-on event is sent to the tone generator 15 (step S13).

Then, it is determined whether or not there are no more note-on events to be read out (step S14). When there is no more note-on event, the present process is terminated. The process returns to step S11.

In step S12, if the read note-on event is an ID meta-event, it is determined whether or not the currently displayed note has a note with the corresponding ID (step S15). If there is no note, a page having a note corresponding to the acquired ID is searched and displayed (step S16). If there is a note with the corresponding ID, step S16 is skipped and step S17 is performed.
Proceed to.

In step S17, note data corresponding to the acquired ID is detected from the musical score logical data, and the corresponding note on the display music is deformed by, for example, changing its display color or blinking. Then, in step S18, it is determined whether a URL or a tag for urging a predetermined operation is inserted at the corresponding ID location.

In step S18, the URL is stored in the corresponding ID location.
Alternatively, when a tag for prompting a predetermined operation is inserted, the corresponding URL is accessed or the inserted predetermined event is activated (step S19), and then the process proceeds to step S14, while the URL is also stored in the corresponding ID location. If no tag for prompting a predetermined operation has been inserted, the process proceeds to step S14 without doing anything.

The processing (3) (step S1)
5, corresponding to S16), the read ID meta-event is the I-value of the last note of the currently displayed musical score.
It may be determined whether or not the score matches D, and if the score matches, the score of the next page may be displayed.

As described above, the musical score information is described in a general-purpose language, that is, XML which is a subset of SGML, so that it can be handled as a document common to other SGML-based languages. Therefore, other SGML, XML
Layer display can be performed simultaneously with a document described in a language conforming to the standard. A plurality of layers can be overlapped.

Therefore, it is possible to create the writing data for the display music score in a separate document and display the data on the display music score as a layer. In this separate document, in addition to the supplementary explanation and the graphic data, a URL and activation of a predetermined event (for example, Java
control information for prompting (a activation). Thus, by clicking a predetermined location on the display music score with a mouse, a predetermined URL can be accessed, an animation can be activated, and various value-added information can be added to the display music score.

Since this language is a common language, the user can easily create layer data.
For example, it can be easily created by a word processor, a drawing application, a homepage creation application, or the like that can output a common format.

Furthermore, if value-added information is inserted into the music information as a tag, an event is started in synchronization with the performance,
If value-added information is inserted into the layer data side in a separate document, it is possible to selectively use an event to start an event.

In order to further increase the added value of the musical score information generated as described above, a dedicated application is prepared and the function is extended.

As the dedicated application, an application having the following functions is prepared.

That is, (1) a function of receiving a MIDI signal from the outside and turning over the music when a predetermined MIDI signal is received; and (2) a function of receiving a MIDI signal from the outside and transposing. When an event (transposition event) is received, a new musical score logical data is generated by calculating the value of the transpose event on the note-on / off pitch data of the musical score logical data, and the musical score is re-formatted with the transcript data. To update the score display by transposing by converting with the style sheet for music and re-displaying the score. (3) Input the usage limit information encrypted in the engraved data and the logical score data as a tag. When printing from a dedicated application, the tag is added to the tag as encryption or watermark data from the print module side. A function that protects the content creator by referring to the number of times of use limit and preventing the music score from being printed beyond this limit. (4) Like a music score input word processor, notes and the like are used as graphic data from the music score display screen A function to change the display screen when the music symbol is input, and also to change the score logical data and the engraved data from the input information.
(5) Function to directly generate performance data from musical score logical data (this function allows musical score logical data to be handled as performance data such as SMF). Yes) etc.

The musical score logical data and the engraving data are in XM format.
L, and the music style sheet is described in a common language that is easy to distribute on the Web, as described in XSL.
Can teach music.

FIG. 9 is a flowchart showing the procedure of the processing performed by the teacher terminal and the student terminal when performing the music lesson via the network.

It is assumed that each of the teacher terminal and the student terminal is constituted by hardware similar to the hardware of FIG. 1, and both terminals are connected to a LAN (local area network).
k).

The network is not limited to the LAN, but may be the Internet.

In FIG. 9, the teacher terminal includes model performance data, musical score logic data, transcript data,
A music style sheet and layer data are created and transferred to the student terminal (or download server) (step S21).

In the present embodiment, the model performance data is transferred (or downloaded) together with the other teaching material data. However, the present invention is not limited to this. Then, it may be transmitted in real time as streaming information.

On the other hand, the student terminal receives the teaching material data (or downloads it from the server) (step S).
31), the musical score logical data, the engraving data, the music style sheet, and the layer data in the teaching material data are converted to obtain music information with a layer (for example, with comments and a curriculum). Model performance data (step S3)
2).

Then, the result of the practice is returned to the teacher terminal (or the download server) (step S33).
Here, as the result of the practice, performance information on the actual performance of the students themselves and layer data as a message to the teacher are created.

As with the model performance data, the student may directly perform the performance data, assign an ID to the performance data, and transmit the data as streaming information in real time.

On the other hand, the teacher terminal receives the training result (or downloads it from the server), evaluates it,
After creating the teaching material for the next step (step S22), the process returns to step S21, and the above processing is repeated.

In the present embodiment, as described above, the displayed musical note is made different from the normal display in synchronization with the performance data during automatic performance.
Automatic performance may be started from a note at a position indicated by the user on the displayed musical score. This can be achieved by the following method.

A pointing cursor for designating a position on the display music is displayed by, for example, the layer data, and the position designated by the user using the pointing cursor is displayed on the display music (display screen of the display device 9). Detect as upper coordinates. Here, it is assumed that the display music is displayed on the display device 9 by supplying the display music to the display device 9 in the format of bitmap data, for example.
The coordinates are detected based on the total bitmap data for one screen. When a note is displayed at the coordinates, that is, the coordinates of the position indicated by the pointing cursor, the note is highlighted, and a note event in the performance data corresponding to the note ID is displayed. By detecting and supplying the performance data after the note event to the tone generator circuit 15,
Automatic performance starts from the note at the position designated by the user.

Further, in the present embodiment, the musical score display graphic information is generated based on the input general-purpose performance data (when general-purpose music data is input, converted into general-purpose performance data). And generates musical performance information. The generated musical score display graphic information is displayed on the display device 9.
To display the music score, and the generated musical performance information is
The musical tone is generated by supplying it to the tone generator circuit 15. However, the present invention is not limited to this, and the musical score display graphic information and the musical tone performance information itself, or the information on which it is based, may be input from different supply sources. For example, the musical performance information is supplied from a music CD, and the musical score display graphic information is
When the music CD is a CD extra, the music data is supplied from a storage area different from the storage area of the musical sound data. When the music CD is a normal CD, another recording medium or the communication network is used. The data is supplied from the server computer 102 via the server 101. The music CD is reproduced by the CD-ROM drive 12 to generate musical tone performance information (in this case, the musical tone data itself), and supplies the musical tone performance information to the tone generator circuit 15. Is supplied to the display device 9 as it is to display the music score. Of course, if the music score display graphic information other than that described in XML is supplied, the supplied music score display graphic information is converted to XML.
Is supplied to the display device 9 after being converted to the one described in the above. When the musical score display graphic information is supplied from the same CD, that is, a CD extra, the musical score display graphic information corresponding to the input musical sound performance information may be input. When supplied from another recording medium or the server computer 101, information relating to the input musical performance information, for example, the title of the music, the name of the performer, the performance date and time, etc., is read from the CD, and the musical score display corresponding to the read information Graphic information is retrieved and input from a target recording medium or the server computer 101. In addition, the reproduction of the music and the synchronization with the displayed music are performed based on the reproduction time of the music. Since the reproduction time of the music is recorded on the CD, it is read and used.

The music performance information is not limited to music data supplied from a music CD, but may be audio data having time information such as audio stream data. Further, instead of or in addition to the musical score display graphic information, a comment on the musical performance information to be reproduced and information such as the reproduction time thereof may be displayed.

Further, in this embodiment, the musical score display is close to the actual musical score as shown in FIG. 6, but the present invention is not limited to this. Is also good.

FIG. 10 is a diagram showing an example of a musical score display in which a note and a piano roll are simultaneously displayed to assist the user in playing. FIG. 10 (a) shows a simultaneous display of normal notes and a piano roll. (B) shows a state where the piano roll pr0 is highlighted (in the illustrated example, inverted) when the note n0 is instructed.

Conventionally, the note and the piano roll are displayed separately, but in the present embodiment, the piano roll is superimposed and displayed at the position of the note. This allows
The user can check at a glance how much the musical tone of each note should be generated, and the performance can be performed more easily.

The length of the piano roll is determined by detecting (or calculating) the time information from the key-on event to the key-off event corresponding to the note, and based on the detection result. , Based on the layer data.

[0140] Instead of the piano roll, the intonation level may be displayed. Here, the intonation level refers to the inflection level when one note is played, and does not mean the inflection level over a bar or a phrase. The intonation level is determined based on the velocity data during the key-on event corresponding to the note, and the display is changed in the same manner as the piano roll, by changing the length of the bar in accordance with the duration of sound generation and by changing the piano roll. Unlike the above, the width of the bar is changed according to the intonation level.
The intonation level is determined by preparing a map of the intonation level corresponding to each note value and each velocity data of the note in advance, and searching this map according to the note value and velocity data of the target note. What should I do? If the intonation level is stored as a difference value between adjacent intonation levels, the storage capacity of the map can be reduced.

Since the performance data in the SMF format does not include a rest event, the conventional apparatus for displaying a musical score based on the performance data in the SMF format does not handle the rest as an event. For this reason, rests could not be edited directly. In the present embodiment, a rest event is generated by analyzing performance data in the SMF format, and the rest event can be directly edited.

The rest event is generated as follows. That is, in the target performance data, whether or not the sounding continuation time from the first note-on event to the corresponding note-off event sequentially from the first note-on event to the corresponding note-off event coincides with the present time of the note-on event located immediately after that. Is checked, if they overlap, it is determined that a rest event is not included between the adjacent notes (note events), and if they do not overlap, the note length corresponding to the mute time is determined. It is determined that a rest event is included.

FIG. 11 is a diagram showing a display example of the generated rest event and an editing example thereof. FIG. 11 (a) shows the generated rest event together with the notes existing across the rest event. (B) shows an example in which the note length of a note existing before and after the rest event is changed (edited) without changing the note length of the rest event in (a). , (C) shows an example in which the note length of the rest event of (a) and the note immediately after it are changed (edited).

In FIG. 11 (a), chords n1 and n
The sound duration of each of the constituent sounds of No. 2 is the same as in FIG.
Piano rolls n11 to n13 and n21 to n23 are displayed, and a time interval between the end of the piano roll n12 and the tip of the piano roll n21 is displayed as an interval i indicating a mute duration.

The automatic performance proceeds, and the automatic performance proceeds to the chord n
When the chord n1 is shifted to 1, the chord n1 is highlighted and the last tone of the constituent tones of the chord n1 ends (piano roll n1).
At the end of 2), the generated rest r is highlighted, and when the silencing duration of the interval i has elapsed, the next chord n2 is highlighted.

In the state where the automatic performance is not performed, the interval i is changed without changing the length of the interval i by using a pointing cursor (not shown) as shown in FIG.
Is moved in the direction of the chord n2 by the length of the chord n2, the length of the piano rolls n11 to n13 is changed to be longer by the length of the arrow a1, and the length of the piano rolls n21 to n23 is shortened by the length of the arrow a1. Be changed. At the same time, the note lengths of chords n1 and n2 are changed to chords n1 'and n2', respectively, and displayed.

When the interval i is changed to be longer by the length of the arrow a2 as shown in (c) using the above pointing cursor, the piano rolls n21 to n23 are changed.
Is shortened by the length of the arrow a2. At the same time, the note lengths of the rest r and the chord n2 are changed to the note lengths of the rests r 'and n2', respectively, and displayed.

As described above, the rest event is generated, so that the performance can be performed more easily, and the rest event itself and events in the vicinity thereof can be easily edited.

By indicating the displayed rest with a pointing cursor, the automatic performance may be started from the rest position. Since the rest is generated as an event, it can be easily realized by applying the above-described method.

In the present embodiment, the musical score is displayed according to the display capability of the display device 9. That is, when there are more musical scores to be displayed than one screen of the display device 9, the musical score is displayed as long as it can be displayed on one screen, and the part that cannot be displayed is the next page and subsequent pages. However, since this cannot meet various needs of the user, the display mode may be changed according to the needs of the user. Specifically, the following display mode is adopted. That is, (1) print space priority display, (2) musical viewability priority display, and (3) playability priority display.

The print space priority display of (1) refers to a display mode in which the number of printed pages (and thus the displayed pages) is minimized, and is a display mode useful for displaying (printing) a score. Specifically, the print space is compressed by detecting the number of notes for each bar and changing the length of the bar break according to the number of bars. This is because if the length of bar breaks is fixed regardless of the number of notes, measures with fewer notes have more blank space (parts with no notes) than measures with more notes, so this is reduced. This is because the user is unlikely to feel uncomfortable.

(2) Musical visibility priority display means that a musically integrated part is placed on the same page (or in the same column).
This is a display mode in which music is preferentially displayed, and is a useful display mode when creating music. More specifically, a symbol or a phrase mark indicating a unit of music is detected, and the position of a page break (or line break) is determined accordingly. If, for example, a phrase break is used as a musical unit, a well-known method is used.
The position of the phrase delimiter may be automatically detected from the performance data, and a page break (or line break) may be performed at this position.

The performance priority display (3) refers to a display mode in which the user is most likely to perform the performance, and is a display mode useful for a part score, a piano score, or the like. More specifically, the position where the rest is present is detected from the performance data, and the display position of the music score is adjusted so that the position becomes the position where the page should be turned. It should be noted that the position to be turned may be set to every even page or every odd page,
The performance priority part may be set.

In a conventional apparatus for displaying a musical score, FIG.
As shown in the music score shown in (a), assuming that four notes (four quarter notes) are displayed in one measure, the one measure section is divided into equal intervals, and even if tuplets are included, When displayed in a divided section, the display interval of each note forming a tuplet is narrowed and it is hard to see. Therefore, as shown in the music score shown in FIG. To change. As a method of changing the display interval, for example, a method of defining a parameter called spacing information for adjusting the display interval according to the type of a note and determining the display interval based on the parameter is known. And the conventional spacing information is
In other words, the conventional spacing information had to be defined for each bar because it was defined to indicate the coordinates within the corresponding bar, so in order to use the spacing information, it was necessary to define each bar. Had to be troublesome.

In order to cope with this, in the present embodiment, the spacing data is defined as follows, and the display interval is adjusted using the spacing data.

FIG. 12 is a diagram showing an example of how to define spacing data and an example of a display result obtained by adjusting a display interval using the defined spacing data.
(A) shows a case where the spacing data is an initial value,
(B) shows a case where the spacing data has a meaningful predetermined value (other than the initial value).

As shown in (a) and (b), the spacing data is defined by a set of (count value, coordinate value). Specifically, in the case of (a), (0, 1
0), (480, 30), (960, 50), (134)
0, 70), (1820, 90), and in the case of (b), (0, 10), (480, 45), (96)
0,65), (1340,75), (1820,90)
It is defined as Here, the count value means time information (sound continuation time) in the performance data in the SMF format, and “480” corresponds to a note length of a quarter note. The coordinates indicate relative coordinates within one measure.

In (b), □ (0,10) and □ (4
80, 45), a quadruple is displayed. That is, the spacing data is defined so that the interval at which the quadruplets are displayed is longer than the interval at which other notes are displayed. And the spacing data is
As can be seen from the illustrated example, since it is a discrete value, it is necessary to determine the intermediate value by interpolation. In the illustrated example, linear interpolation is adopted as the interpolation method.
The interpolation method may be changed according to the type of the note.

As for the spacing data, various combinations of data are created in advance, stored as table data, and the user can select from the table data. This eliminates the need for the user to create the spacing data from scratch. . If the spacing data desired by the user does not exist in the table data, the data closest to the user's preference may be selected and edited.

Also, unlike the conventional spacing information, the spacing data is defined as general-purpose data irrespective of the measure to be applied.
Two spacing data can be applied. Of course, the spacing data may be applied to only one predetermined bar.

As described above, since the spacing data is patterned and can be shared over a plurality of measures, it is possible to save the time and effort of creating the spacing data and to reduce the data capacity. . Further, as a result of applying and displaying certain spacing data, when the result does not match the user's preference, another spacing data can be applied immediately, and the operability of the user is improved.

Next, a method of automatically generating a part of the musical score logical data from the performance data in the SMF format will be described.

Some meta-events included in the performance data in the SMF format indicate the type of musical instrument to be used in each part. By detecting and analyzing this meta-event, the musical instrument to be displayed on the musical score is displayed. You can know the type of. On the other hand, for each type of musical instrument, a template containing a clef to be used, the number of display steps, transposition information, notation information (for example, note heads, display when a musical part is protruded, etc.), a musical instrument organization list, and the like Have prepared. And
Depending on the type of instrument obtained by analyzing the meta-event of the input performance data, one of the templates is selected, and a part of the musical score logical data is selected based on the information described in the template. Generate automatically. For example, determination of the order of arrangement of each part displayed on the display music score, display of the name of the instrument to be played in each part, selection of a clef suitable for the instrument, and the like.

FIG. 13 is a diagram showing an example of a display when a part of the score logical data automatically generated in this manner is actually displayed. As shown in the figure, a musical instrument name is displayed in each part, and a clef and a key signature (by transposition) corresponding to the musical instrument name are displayed. The arrangement of the parts is also determined according to a predetermined rule, that is, a rule corresponding to the musical instrument composition automatically recognized based on the type of the detected musical instrument and the selected template.

In the above example, each part is played by one type of musical instrument from the beginning to the end of the musical piece. FIG. 14 shows an example of a musical piece of such a type that is displayed when a part that requires switching of musical instruments is displayed in a musical score.

[0166] In the figure, (a) shows MIDI in the middle of music.
(B) shows a case where the musical instrument is changed from “Alto Saxophone (A.Sax)” to “Tenner Saxophone (T.Sax)” by the “program change” of the message;
Shows an example of a display separately displayed for each instrument when the sax part is as shown in (a), and (c) shows each instrument in one row when the sax part is as shown in (a). 13 shows an example of a display in which a holding display is performed.

Also in this case, as described with reference to FIG.
A part of the musical score logical data is generated based on the selected template. However, in this case, it is necessary to prepare two types of templates, one for performing separate display and the other for performing holding display, and select one of them according to a user's instruction. .

Further, as the number of parts to be displayed on the musical score increases, the management of each part becomes more troublesome. Therefore, a method for facilitating the management is desired. FIG.
FIG. 6 is a diagram for explaining a method of easily managing a large number of parts. The method for managing a large number of parts is not limited to a device for generating and displaying music score information described in a general-purpose language based on general-purpose performance data. It can also be applied to things.

In FIG. 15A, the entire instrument is set as a root, and the entire instrument is divided into a plurality of categories. For example, woodwind instruments (Wood), brass instruments (B
ras), stringed instruments, percussion instruments (both not shown), and the like. Those in these categories are set as the lower layers of the root.
