2. Description of the Related Art It is very difficult for beginners to learn a musical instrument playing method while learning a musical book on which a musical score or the like is being played and actually operating the musical instrument in a stepwise manner. is there. Thus, in recent years, it has become possible to learn a musical instrument playing method by giving a musical instrument playing instruction on a display. In the performance instruction of the musical instrument, for example, a partial image of the musical instrument for which the user wants to learn the performance method is displayed on a predetermined display, and the position of the current operation operation target on the displayed musical instrument is reproduced. Are sequentially instructed in accordance with. That is, fingering indicating which finger should be used to operate the musical instrument is displayed as the music progresses. The user can easily learn the playing method of the musical instrument by following the performance instructions displayed on the display. When such fingering is shown on the display, it is necessary to previously generate fingering information indicating a finger used to operate each note (that is, fingering). Therefore, a device for performing fingering by analyzing a plurality of pitch information representing each pitch of a series of note strings included in performance data and automatically generating fingering information for each note has been proposed. It is conventionally known (for example, Japanese Patent Application Laid-Open No. Hei 7-26175 filed by the present applicant.
0, etc.). Also, if the performance data is composed only of a plurality of pitch information representing each pitch of a series of note strings, a mechanical expressionless performance is reproduced and it is very unnatural, so that a more natural In order to make the performance lively, it is necessary to add, as control data, performance information representing a musical expression unique to each of various musical instruments (that is, musicality) (that is, expression). Therefore, a device for analyzing performance data and automatically giving a facial expression has been conventionally known (for example, Japanese Patent Application Laid-Open No. 10-105173 filed by the present applicant).

[0003]

By the way, in a conventionally known apparatus for automatically performing fingering and facial expression, performance data is transferred from the beginning to the rear of the music (that is, in the forward direction according to the flow of the music). 2) By searching, fingering and expression are given in the order of progress of the song. However, in some cases, it is sometimes more appropriate to perform fingering and facial expression by referring to the performance data in the rear while performing fingering and facial expression. Therefore, in the conventional device, in order to perform appropriate fingering and facial expression, complicated processing such as checking the performance data at the rear and returning to the previous performance data to perform fingering and facial expression is performed. And the processing efficiency is poor. In addition, in the conventional device, especially when fingering is performed on a stringed instrument, fingering is not performed in consideration of the position of a hand to be placed when holding down a string during performance, so that smoothing is performed during performance. There is a problem that it is difficult to perform fingering capable of performing various operations.

[0004] The present invention has been made in view of the above points, and by performing simple processing without performing complicated processing, it is possible to perform fingering and various musical instruments capable of performing continuous operations. It is an object of the present invention to provide a musical performance data processing apparatus and method and a storage medium capable of efficiently performing the musical expression of the musical performance.

[0005]

A performance data processing apparatus according to the present invention comprises: performance data supply means for supplying performance data including at least a plurality of pitch information representing respective pitches of a series of note strings; Information generating means for analyzing a plurality of pitch information included in the supplied performance data and automatically generating predetermined performance related information, wherein the information generating means performs The predetermined performance-related information is generated by searching and analyzing in a direction opposite to the order.

[0006] The information generating means retrieves a plurality of pieces of pitch information respectively representing the pitches of a series of note strings included in at least the performance data in a direction opposite to the performance progression order, and obtains the pitch information obtained by the search. Is generated to generate predetermined performance-related information. That is, in order to generate the predetermined performance-related information, the pitch information included in the performance data is sequentially traced from the last pitch information played during the performance to the first pitch information played during the performance. To search and analyze the searched pitch information. In this way, it is possible to generate predetermined performance-related information that cannot be generated properly unless it is processed while referring to the subsequent performance data only by retrieving the performance data in the reverse order of the performance progress. . That is, it is possible to efficiently generate appropriate performance-related information simply by performing a simple process such as analysis of pitch information according to a backward search of performance data.

In a preferred embodiment of the present invention, the predetermined performance-related information is fingering information indicating a finger to be operated when playing each note using a predetermined musical instrument. Alternatively, the predetermined performance-related information is performance information for adding a musical expression unique to a predetermined musical instrument to a musical tone. In order to generate optimal fingering information and performance information, it is necessary to search and analyze performance data from the reverse direction, so it is possible to generate such information simply by searching for performance data in the reverse direction of the performance progression. What can be done is very advantageous.

Further, the performance data processing apparatus according to the present invention comprises: performance data supply means for supplying performance data including at least a plurality of pieces of pitch information representing respective pitches of a series of note strings; Information generating means for analyzing a plurality of pitch information included in the data to generate fingering information indicating a playing finger of the stringed instrument, wherein the information generating means is arranged in accordance with an area of the playing position in the stringed instrument. The fingering information is generated according to different fingering patterns. According to this, the fingering information is generated according to different fingering patterns according to the performance position area of the stringed instrument, so that the optimal fingering that can perform continuous fingering according to the performance position is performed. Finger information can be generated.

The present invention can be constructed and implemented not only as a device invention, but also as a method invention. Further, the present invention can be implemented in the form of a program of a processor such as a computer or a DSP, or can be implemented in the form of a storage medium storing such a program.

The performance data processing apparatus according to the present invention automatically analyzes the performance data and automatically generates various information related to fingering and facial expression (that is, fingering information and performance information). First, a process of automatically generating information on fingering based on performance data is described with reference to FIG.
This will be described with reference to FIG. FIG. 2 is a flowchart showing one embodiment of the "fingering process" executed by the CPU 1 in the performance data processing device. However, in this embodiment, a description will be given of a case where fingering is performed on a stringed musical instrument, particularly a stringed musical instrument in which the pitch is determined by pressing a string with a finger. Hereinafter, the processing operation of fingering in this processing will be described with reference to the flowchart of FIG. In the following description, in order to make the description easy to understand, the description will be given by taking an example of fingering when a cello is used as a stringed instrument. The open strings in the case of a cello are "A string", "D string", "G string", and "C string", and the pitches when each string is played in an open state are "A2" and "D2" for convenience. Here, "G1" and "C1" are shown. The number added after the pitch indicates an octave higher or lower octave. For example, “A1”, “A2”, and “A3” indicate the sound of “A” whose pitch is raised by one octave in order. Show.

In step S1, a position of the first priority is set. In other words, fingering is started with the position of the first priority as the first position according to the priorities assigned to the positions in advance when fingering is applied. Here, the “position” will be briefly described. For example, when playing a stringed instrument that determines the pitch by holding down a string, such as a cello, the fingers move around on the fingerboard and play different pitches by pressing the strings at different positions on the fingerboard. Is available. That is, in the case of such a stringed instrument, when the position of the finger (that is, the hand) on the fingerboard is determined, the range of the sound pitch that can be emitted therefrom is determined. The positions of the hands on the fingerboard are generally called a first position, a second position, a third position, and a fourth position in order from the lowest sound. That is, the first position is a position where the forefinger is located at a position where a sound that is a whole tone (that is, two semitones) from the sound played by the open string is made, and the other fingers are located at a position where a sound with a semitone interval is made. The second position is the first position
This is the position shifted from the position to the semitone or two semitone high pitch side. The third position is a position shifted from the first position to the third semitone upper side. The fourth position is a position shifted from the first position to the fifth semitone upper side. However, in this embodiment, a position one semitone below the first position is newly defined as "position 2" and the first position is defined as "position 3" for convenience. Number and redefine to increase by one. In this way, in this embodiment, the position generally called the first position is “position 3”, the position called the second position is “position 4”, the position called the third position is “position 6”, and the fourth position is called “position 6”. The position called the position will be called “position 8”. The priority order is set in advance for each of such positions, and the position to be used for fingering is determined according to the priority.

In the cello, position 3 (ie,
It is generally said that the first position) is the easiest to play and then position 8 (ie the fourth position) is the easiest to play. Therefore, step S
In step 1, based on the priorities assigned to the positions in advance, the position with the highest priority among the priorities is set as the position to be used first when fingering is performed. In order to rank the positions, for example, position 3 (that is, the first position), position 8 (that is, the fourth position), position 4 (that is, the second position), and position 6
(That is, the third position),..., Etc., may be appropriately set by the user. In this embodiment, it is assumed that the position number is associated with the position of the index finger when each finger is not in the extended state (described later) but in the basic state (described below). Also, it goes without saying that the position is not limited to position 2 to position 8, but in general, in the normal range when a cello is used, up to about position 9 is often used. It is efficient and preferable to examine positions 2 to 9. However, if the range of the song is high, it may not be possible to play until position 9, so check the highest tone in the song in advance and set the position necessary for fingering appropriately. You may.

In step S2, a forward fingering check process is performed. That is, fingering is started based on the position set in step S1. As will be described in detail later, in the forward fingering check processing in step S2, the performance data is searched in the order of progress of the music (that is, in the forward direction), and the pitch of the appearing note (that is, pitch information) is determined in step S1. It is determined whether or not the pitch is within the playable range at the position set in step 2. If the pitch is playable, the finger is fingered at the position. For example, if the set position is position 3 and the pitch of the fingering target is “C3”, the note number is set to use the finger number “2” of position 3 in the “A string”. Fingered against. This finger number is a number given to each finger for convenience similarly to the position. The finger number “1” is for the index finger, the finger number “2” is for the middle finger, the finger number “3” is for the ring finger, and the finger number. The number “4” is assigned to each little finger. Therefore, when the pitch of the note to be fingered is “C3”, the finger number “2” of the position 3, that is, “A”
The fingering is determined so as to press the “string” with the middle finger in the first position.

In step S3, the forward fingering check processing in step S2 is performed to move the fingering from the beginning to the end of a section to be fingered (hereinafter, a predetermined section of a song to be fingered is called a "phrase"). It is determined whether or not fingering has been performed. When the fingering has been assigned to the end of the phrase, that is, when all the notes existing in the phrase have been fingered (YES in step S3), the process proceeds to step S4.
On the other hand, when the fingering cannot be performed until the end of the phrase, that is, when the fingering can be performed only to a halfway note in the phrase (NO in step S3), the reverse fingering check process (step S5). )I do. That is, fingering is started based on the position set in step S1. As will be described in detail later, step S
In the reverse fingering check process of No. 5, the performance data is searched in the opposite direction (ie, in the reverse direction) to the progression of the music, and the pitch of the appearing note (ie, pitch information) is set to the position set in step S1. It is determined whether or not the pitch is within a playable range. If the pitch is playable, the finger is fingered at the position. As a result of the reverse fingering check processing, it is determined whether fingering has been applied to all the notes from the end to the beginning of the phrase as in the forward fingering check processing (step S6). When the fingering can be assigned to all the notes from the end to the beginning of the phrase by performing the reverse fingering check process (YES in step S6), the process proceeds to step S4.
On the other hand, even when the reverse fingering check process is performed, if fingering can be performed only to a note in the middle of the phrase (NO in step S6), forward fingering is performed for all positions. It is determined whether the check process and the reverse fingering check process have been performed (step S7). If the above processing is not performed in all positions (NO in step S7), the position used for fingering is reset to the position of the next priority (step S9), and the processing in step S2 is performed. Return to
That is, in order to perform fingering again for all the notes over the entire phrase using the new position, the above-described processing is repeatedly performed using the position of the priority following the already processed position. If the above processing has already been performed for all positions (step S7
YES), a fingering at a position where fingering can be performed farthest (that is, continuously for many notes) is selected, and the phrase is divided at that position as shown in FIG. In order to perform fingering on the notes in the section, the remaining phrases not fingered out of the divided phrases are reset to the target section to be newly fingered (step S8). Then, the process returns to step S1, and the processes from step S1 to step S9 are repeatedly performed.

Here, the phrase division performed in step S8 will be briefly described with reference to FIG. FIG.
FIG. 4 is a conceptual diagram for explaining a method of determining a phrase division position when dividing a phrase. The upper part of FIG. 3 shows the case where the pitch of the note is checked from the beginning of the phrase and fingering is performed (that is, in the case of the forward fingering check processing), and the lower part of FIG. 3 shows the pitch of the note from the end of the phrase. Is checked and fingering is performed (that is, the case of the reverse fingering check process). In these figures, the shaded portions indicate the phrase ranges in which the fingering can be continuously performed. In the above step S8, the fingering at the position where the fingering can be performed to the farthest note is selected, the phrase is divided at that position, and the fingering is newly added to the notes included in the remaining portion. I do. In the example shown in FIG. 3, fingering is performed to the farthest note in the case of checking from the beginning shown in the upper part, as compared with the case of checking from the end shown in the lower part. Therefore, in this case, the phrase is divided into a hatched area and a non-hatched area when checked from the beginning. Then, the range not shaded is reset as a phrase to be newly fingered, and the fingering process is repeatedly performed so that fingering is performed for the entire new phrase. In step S8, if there are a plurality of fingerings at the position where the fingering can be performed to the farthest position, the fingering at any one position may be selected based on a predetermined condition. . For example, following the priority of the position, giving priority to fingering that does not use extensive forms, giving priority to fingering that does not use little fingers,
Selection is made using conditions such as

Returning to FIG. 2, when fingering is performed on all the notes in the phrase (YE in step S3)
S), the fingering at the set position is determined (step S4), and the fingering attaching process ends. In other words, when fingering with a small amount of position movement (ie, no significant position change from the beginning to the end of the phrase) with respect to all pitches existing in the phrase can be performed, the fingering is determined. I do. In this way, by combining phrases that have been fingered with a small amount of position movement, it is possible to perform fingering for an entire song.
As described above, in the performance data processing device according to the present invention, on the condition that the position movement is as small as possible,
Efficient fingering (that is, fingering) can be determined. In other words, for each phrase, the number of notes that do not need to be moved as many as possible from the first note is determined to be the one with the smallest number of position movements, and thereafter, the number of position movements from the next note that needs to be moved to the next position is minimized. Look for things. In this way, it is possible to obtain the fingering with the minimum number of position movements through one song. In the fingering processing described above, when searching for the one with the smallest number of position movements, not only the forward direction according to the progress of the song but also the note in both the reverse direction opposite to the progress of the song is searched, so that it is efficient. The fingering can be performed.

Next, the forward fingering check process (see step S2) and the backward fingering check process (see step S5) executed in the above-mentioned fingering attaching process will be described with reference to FIG. Figure 4 shows the forward (or reverse) direction
It is the flowchart which showed one Example of fingering check processing. Hereinafter, the processing operation in the processing will be described with reference to the flowchart of FIG. The forward fingering check process and the reverse fingering check process are performed when the fingering process is performed from the beginning to the end of the phrase (in the case of the forward fingering check process: This is only the difference between the processing from the end of the phrase to the beginning and the processing from the end of the phrase to the beginning (in the case of the reverse fingering check processing: hereinafter, simply referred to as reverse processing). And the reverse fingering check process will be described using the same flowchart.

In step S11, the note to be fingered is set to the note at the beginning of the phrase (for forward processing) or the last note of the phrase (for reverse processing). That is, the performance data for the phrase is searched for in the forward or reverse direction, and the note detected first among the individual notes constituting the music according to the performance data is set as the note to be fingered. In step S12, at the set position (step S1 or step S9 in FIG. 2).
Reference), it is determined whether or not fingering can be performed on a note set as a fingering target. That is, it is determined whether or not any of the fingers in the basic state of the set position is located at a predetermined position on the fingerboard to be pressed in order to sound the pitch of the detected note. When it is determined that fingering is possible at the set position (YES in step S12), the fingering of the musical note is determined as the fingering (step S13), and the process goes to step S14. On the other hand, when it is determined that fingering is not possible at the set position (NO in step S12), it is determined whether fingering with extended fingering is possible (step S17).
That is, when fingering cannot be performed on the note using the basic state at the set position, can the fingering be performed on the note using the expanded state at the set position? Determine whether or not. The basic state and the extended state indicate the shape of the left hand in the low position (that is, the first position to the fourth position), and those in which the fingers are arranged at equal intervals are referred to as a “basic state” (that is, a basic form) and a forefinger. An object having a wide space between the middle finger and the middle finger is called an "extended state" (that is, an extended form). As a method of changing from the basic state to the extended state, a method of extending only the index finger at the middle finger, the third finger, and the little finger (hereinafter, referred to as “ascending extension”), and a method of changing the middle finger, the third finger at the same position as the ascending finger And a method of moving the little finger (hereinafter, this is referred to as “downward extension”). Then, for example, when the set position is position 3, the pitch range that can be played when the “A string” is pressed using the basic form is “B2”, “C3”, “C3♯”, “D”.
3 ". The range of pitches that can be played when the “A string” is depressed using the extended form is “B2”, “C3”, “C3”.
“A3♯” in addition to “♯” and “D3” (when ascending is expanded)
And “D3 $” (when extended downward).

In this embodiment, the reach of each finger is basically fixed at one semitone, except that the index finger can be extended by one semitone (ie, two semitones). Of course, the present invention is not limited to this, and it may be configured such that the reach of each finger is made different according to each position. For example, in a cello, the higher the position (ie, the closer to the piece side), the narrower the interval between positions on the fingerboard at which different sounds can be emitted for each semitone, and therefore, the higher the position, the more distant sound ( In other words, each finger reaches a position on the fingerboard at which a pitch can be emitted. Therefore, the reach of each finger is made different depending on each position. In such a case, an extended range table in which the range of the finger that can be extended for each position is set is stored in the external storage device 9 or the like in advance, and in the above-described step S17, extended fingering is performed based on the extended range table. It may be determined whether fingering is possible. An example of such an extended range table is shown in FIG. FIG. 5 is a conceptual diagram showing one embodiment of the extended range table.

The extended range table is a table in which a range that each finger can reach, an extended range, and the like are set for each position.
“Position” represents a position number when the position a semitone below the first position is redefined as position 2 and the first position as position 3 for convenience as described above. The “range that each finger can reach” represents a range in which the index finger, the middle finger, the ring finger, and the little finger can reach in the basic form (that is, a range in which the strings can be pressed by each finger). The “extended range” represents an allowable range in which the strings can be held down when the index finger is further extended from the “range that each finger can reach” (that is, in the extended form). In this embodiment, for example, in the positions 2 to 6, since the “range of reach of each finger” is “1”, the index finger, the middle finger, the ring finger and the little finger can be arranged at intervals of one semitone as a basic form. In positions 7 to 11, the “reaching range of each finger” is “2”, so that the index finger,
The middle finger, ring finger, and little finger can be arranged at intervals of one semitone or two semitones. In addition, since the “extended range” is “1” in each position, for example, in positions 2 to 6, not only the index finger can hold a string of one semitone but also the “extended range” of each finger. It is also possible to extend the basic form by two semitones (that is, the whole tone) and hold down the string (that is, “1” in “range of reach of each finger” and “1” in “extended range”). To increase the reach of the index finger by “2”.
(1 + 1) "for a semitone). FIG.
The example shown in Fig. 1 shows the relationship between the position and the reach of the finger. However, in the case of a cello, when the position is increased, parts other than between the index finger and the middle finger may be expanded. At position 7 and above, the thumb may be used instead of using the little finger. In such a case, the distance between the thumb and index finger is quite flexible,
If fingering is not possible, fingering may be performed so as to leave it to the thumb. In the above-described embodiment, such a case is omitted and simplified for the sake of simplicity.

Returning to FIG. 4, when it is determined in step S17 that fingering with extended fingering is possible (YES in step S17), each finger is measured at the extended position (described later). ) Set to move (step S1)
8) Go to step S13. In this step S18, the currently set position is increased by one when the extended fingering is the ascending extension so that the currently set position is increased by one when the extended fingering is the descending extension. Go down and reset your position.
For example, when the fingering is performed in the forward processing or the backward processing in the downward extension of the position 3, the position used for the fingering is reset from the position 3 to the position 4, and the processing is continued. When the fingering is performed in the forward processing or the backward processing in the ascending extension of the position 3, the position used for the fingering is reset from the position 3 to the position 2, and the processing is continued. In this way, in the forward fingering check process and the backward fingering check process, it is determined whether or not fingering with extended fingering is possible. By fingering (refer to step S17), fingering is performed so that a performance using the length measurement technique can be performed. For example,
When the first string (that is, the A string) of the cello is pressed using the position 3 (that is, the first position), the position of the index finger is located at the position where the pitch of B is emitted, but the finger of B is being fingered. Move the finger other than the index finger to change the position to position 4. In other words, the position of the other finger is raised by a semitone while holding down the "A string" with the index finger, thereby changing the position 3 to the expanded form. If the index finger is returned from the extended form to the basic form while another finger other than the index finger is moving at the next note, the position can be shifted by a semitone while the fingering is continued. In the state where such fingering is continued, that is, when the extended form and the basic form between the adjacent positions are repeatedly performed, the finger can move while moving on the fingerboard like a measuring insect, so that this embodiment is performed. Such a playing technique in which a finger moves on a fingerboard like a measuring insect is called "a measuring insect playing technique (abbreviated as a measuring technique)". When fingering is performed so as to perform such a measure, it is possible to perform a performance with fingering having a small position shift. That is, continuous fingering can be performed, which enables smooth fingering without any kind of position movement in which all fingers must be moved at the same time.

On the other hand, if it is determined in step S17 that fingering cannot be performed even with the use of extended fingering (NO in step S17), fingering failure is determined (step S19), and fingering can be performed. The position up to the played note is stored (step S20), and the check processing ends. In this case, continuous fingering by the same position,
Alternatively, since the continuous fingering by the measuring movement can be performed only up to the note to be fingered, the position up to the note at which the continuous fingering can be performed is stored. The stored position up to the note to which the fingering can be applied is used when it is determined whether or not the fingering has been applied to the end of the phrase in the above-described fingering processing (steps S3 and S in FIG. 2).
6), and is used as a phrase division position when a phrase is divided (see step S8 in FIG. 2). In this way, even if continuous fingering cannot be applied to the entire song, the entire song can be composed of a plurality of phrases that have been continuously fingered. In other words, it is possible to perform fingering with less position movement.

When fingering can be performed in the basic form or the extended form at the set position (step S1).
2 or YES at step S17), the fingering is determined as the fingering to be attached to the note to be fingered (step S13). Then, it is determined whether fingering has been completed up to the last or leading note of the phrase (step S14). That is, it is determined whether or not fingering has been performed on all the notes included in the phrase. If fingering has not been completed up to the last or first note of the phrase (NO in step S14), in this case, fingering has not been performed on all the notes included in the phrase, and thus fingering has been performed. The target note is set to the next note (step S16), and the process returns to step S12. That is, a note to be fingered is newly set, the above-described processing is repeated, and fingering is sequentially performed on the note. If the fingering is completed up to the last or leading note of the phrase (YES in step S14), in this case, the fingering has been performed on all the notes included in the phrase. (Step S15), and the process ends.

A specific example of fingering performed by the fingering processing and the forward (or reverse) fingering check processing (see FIGS. 2 and 4) will be described with reference to FIG. FIG. 6 is a diagram showing a specific example of the fingering result when the fingering process and the forward (or reverse) fingering check process are performed, and FIG. 6A illustrates fingering from the forward direction. FIG. 6B shows a case where fingering is performed in the reverse direction (ie, a reverse fingering check process). In this embodiment, in order to make the explanation easy to understand, “A♯ → C → B → C
A description will be given of fingering of a cello when a phrase progressing in the order of “♯ → C → E” can be played using only the first string (that is, “A string”). That is, here, the fingering of the cello will be described using a phrase that can be played using only the "A string" of the cello. FIG. 6 shows the position of each finger at each position on the fingerboard. The upper part of the figure shows the pitch of the note to be fingered, and the left side of the figure shows the numbers P2 to P8 indicating the positions on the fingerboard. (For example, P2 represents position 2), and the position determined as fingering is shown in the lower part of the figure. Numerals 1 to 4 in the figure indicate finger numbers for each position determined as fingering, and circles in the figure indicate “A「 → C →
For convenience, the position of the “A string” which must be pressed by the user to produce each sound of “B → C♯ → C → E” is shown. In the following description, position 3, position 8, position 4
It is assumed that the priorities are set in descending order.

When the fingering process is started, the first priority position 3 is set and the process proceeds to the forward fingering check process (see steps S1 and S2 in FIG. 2). In the forward fingering check process, the leading "A $" of the phrase is set as the note to be fingered (see step S11 in FIG. 4).
When fingering is performed for the leading "A $", fingering cannot be performed in the basic form (P3) of position 3 set according to the priority order, and therefore fingering is performed in ascending extension (P3U) of position 3. (Step S1 in FIG. 4)
2 and S17 and S13). That is, the fingering information added to the pitch information “A $” in the performance data is “A
Strings, “ascending position 3”, and “finger number 1”. Next, the note to be fingered is set to the next note, that is, “C” immediately following “A♯” (steps S14 and S1 in FIG. 4).
6). The fingering for "C" is performed by taking a measure when fingering for "A @" (step S18 in FIG. 4).
Is performed at position 2 since the above is performed. Since fingering can be performed on the "C" in the basic form P2 of the position 2, it is added to the pitch information "C" immediately following the pitch information "A $" in the performance data. The fingering information is “A string”, “Position 2”, and “Finger number 3”. Thus, "C" after "A $"
Fingering can be performed continuously using the basic form (P2) of the position 2 for all of “B”, “C♯”, and “C”. That is, “A string”, “Position 2”, “Finger number 2” for pitch information “B”, “A string”, “Position 2”, “Finger number 4” for pitch information “C「 ”, "A string""position2""finger number 3" for high information "C"
Are generated as fingering information. By the way, FIG.
As shown in (A), for the last phrase "E" at the end of the last phrase, not only the basic form of position 2 (P2) but also the sounding of "E" even if the descending extension (P2L) of position 2 is used. Your finger never reaches the position where you can. That is, fingering cannot be performed on the “E” by using the position 2 and fingering cannot be performed by moving the scale. Therefore, the position of the note that could be fingered as a fingering failure was stored (step S in FIG. 4).
19 and S20), and the forward fingering check process ends. As described above, fingering information for performing fingering as shown in FIG. 6A is generated and temporarily stored in a memory or the like.

Returning to the fingering attaching process, since the fingering could not be attached to the end of the phrase in the forward fingering checking process, the reverse fingering checking process is performed next (steps S3 and S5 in FIG. 2). reference). In the reverse fingering check process, the last "E" of the phrase is set as the note to be fingered (see step S11 in FIG. 4). When fingering is performed for the last “E”, fingering cannot be performed with the basic form (P3) of position 3 and the extended form (P3U and P3L) of position 3 set according to the priority order. The reverse fingering check process is terminated without generating fingering information for the pitch information "E" in the performance data, and the process returns to the fingering attaching process. In this way, if the fingering cannot be applied to the end of the phrase despite the forward fingering check process and the reverse fingering check process, the next priority position 8 is set and the above process is performed. This is repeated (see steps S7 and S9 in FIG. 2).

When the forward fingering check processing is performed at position 8, fingering cannot be performed on "A $" at the beginning of the phrase. Fingering can only be given to "E". Therefore, also in this case, the position 4 of the next priority is set and the above processing is repeated. When the forward fingering check processing is performed at the position 4, since the fingering cannot be applied to "A $" at the beginning of the phrase, the backward processing is performed. When fingering is performed on the last "E" of the phrase in the reverse fingering check processing, fingering cannot be performed with the basic form (P4) of position 4 set according to the priority order, so that the descending extension of position 4 ( P4
In L), fingering is performed (see steps S12, S17, and S13 in FIG. 4). That is, the fingering information added to the pitch information “E” in the performance data is “A string”, “position 4 descending”, and “finger number 4”. Next, the note to be fingered is set to the next note, that is, “C” immediately before “E” (see steps S14 and S16 in FIG. 4). The fingering for "C" is performed at position 5 because the fingering movement for "E" has been performed (see step S18 in FIG. 4). Since fingering can be performed on the “C” by the ascending extension (P5U) of the position 5, the pitch information “C” immediately before the pitch information “E” in the performance data is added. The fingering information is “A string”, “ascending position 5”, and “finger number 1”. The fingering for “C♯” immediately before “C” is
Position 4 has been taken since the scale movement (see step S18 in FIG. 4) has been performed at the time of fingering for “C♯”.
Done in Since fingering can be performed on the “C” in the basic form of position 4 (P4), the fingering information added to the pitch information “C♯” in the performance data is “A string”. "Position 4" and "finger number 2". Fingering for “B” immediately before “C♯” is performed at position 4. Since fingering can be performed on the “B” in the ascending extension (P4U) of the position 4, the fingering information added to the pitch information “B” in the performance data is “A string”. ”“ Position 4 ascending ”“ Finger number 1 ”
Becomes The fingering for “C” immediately before “B” is
This is performed at position 3 because the measuring movement (see step S18 in FIG. 4) has been performed. Since fingering can be performed on the “C” in the basic form of position 3 (P3), the fingering information added to the pitch information “C♯” in the performance data is “A string”. ”“ Position 3 ”
"Finger number 2" is obtained. The fingering for “A $” immediately before the “C” is performed by measuring (see step S18 in FIG. 4).
Is performed at position 3 since the operation is not performed. Ascending extension of position 3 (P3
Since the fingering can be performed in U), the fingering information added to the pitch information “A $” in the performance data is “A string”, “ascending position 3”, and “finger number 1”. . In this way, when fingering is started in the direction opposite to the order of progression of the phrase using the position 4, "A の"
All of "C", "B", "C $", "C", and "E" can be continuously fingered. Therefore, in this case, FIG.
The fingering is determined as shown in (B) (see steps S6 and S4 in FIG. 2). As described above, continuous fingering can be easily determined only by performing a simple process such as performing a search not only in the forward direction but also in the reverse direction.

When continuous fingering can be performed by performing the reverse fingering check process, it is necessary to convert a part of the fingering information generated in the reverse fingering check process. That is, ascending extension and descending extension performed in the backward fingering check process correspond to descending extension and ascending extension in different positions in fingering from the forward direction, The fingering information about the descending extension must be converted. For example, in the above-described specific example, in the reverse fingering check process, when the fingering is performed in the ascending extension when the transition from “E” to “C” is performed, and when the transition from “C「 ”to“ B ”is performed. Also has fingering with ascending extension. Therefore, when the fingering information is converted so as to correspond to the fingering from the forward direction, the fingering information added to “C” is “A string”, “position 4 descending”, “finger number 1”. The fingering information given to “B” is “A string”, “downward in position 3”, and “finger number 1”. As described above, when fingering is performed by “upward extension” and “downward extension” in the reverse fingering check process, the generated fingering information must be converted.

Next, expression will be described. If the performance data is composed only of the pitch information of a series of note strings, a mechanical expressionless performance will be reproduced and it is very unnatural, so in order to make the performance more natural and vivid It is better to add, as control data, performance information representing a musical expression unique to each musical instrument (that is, musicality) (that is, expression). For example, a hammering-on or pulling-off playing technique is known for stringed instruments such as a guitar, and by using this hammering-on or pulling-off playing technique in an ordinary manner, it is possible to create a guitar-like expression. Can be. The performance data processing device according to the present invention can not only generate fingering information by the fingering processing as described above, but also generate information related to expression adding a musical expression to a musical tone. Therefore, an expression adding process for adding a musical expression to a musical tone will be described with reference to FIG. FIG. 7 is a flowchart showing an embodiment of the facial expression attaching process. Hereinafter, the operation of the facial expression processing will be described with reference to FIG.

In step S31, the performance data is divided into phrases. As a method of dividing the phrase in this case, the phrase may be divided using the following rules. For example, if there is a silent part, it is set as a section break. If there is a note longer than a pre-specified note value, it is set as a section break. If sounds of the same pitch continue, the section is delimited. However, in such a case, the first note of the same pitch is included in the section (that is, if notes of the same pitch are consecutive, the last note of the same pitch is the next note). At the beginning of the section). If the interval between consecutive notes is four or more semitones apart, it is defined as a section break. In this case, 4
The interval up to the note before the semitone is included in the section. Of course, other methods may be used. For example, the fingering evaluation described above is performed in advance, and as a result, a portion evaluated as having a different performance string may be used as a phrase delimiter. In step S32, the first phrase is selected from the divided phrases. In step S33, the last two notes in the selected phrase are paired. In step S34, expression data is assigned to each pair. For example, hammering-on, pulling-off, etc. in the case of a guitar are given to notes forming a pair. In step S35, it is determined whether or not there are two or more notes before the pair to which the expression data is added. If there are two or more notes (YES in step S35), the two preceding notes are paired (step S36), and the process returns to step S34. On the other hand, if there are no two or more notes before (step S3
(NO in 5), it is determined whether or not the processing has been completed up to the last phrase (step S37). When the processing is completed up to the last phrase (YES in step S37), the processing is ended. If the processing has not been completed up to the last phrase (NO in step S37), the next phrase is selected (step S38), and the process returns to step S33.

As described above, the notes in the phrase are sequentially shifted from the end of the phrase, that is, two times in the direction opposite to the progression of the music.
A pair is formed by combining them one by one, and expression data is given to the pair. Then, the above processing is repeated until the assignment of the expression data is completed for all the divided phrases. By doing so, it is possible to efficiently express expressions that can express guitar-likeness even if sufficient musicality is not obtained, by processing from the reverse direction of the song's progression order become. In the case where expression data is given to a pair of two sounds in this way, the phrase delimiter position (that is, the last pair in the phrase)
It is preferable that the expression data is added to the phrase, and it is better that there is no single note at the break position of the phrase. In the case of the forward processing, it is necessary to confirm that there is no single note at the phrase delimiter position (for example, the number of notes in the phrase is an even number). By forming a pair at a time, the above-described confirmation processing can be omitted. In the above embodiment, all the notes in the phrase are sequentially combined to form a pair and the expression data is added. However, the expression data is added to all the pairs formed by sequentially combining all the notes in such a phrase. The expression data may be added only to the pair that satisfies the predetermined rule, instead of the expression data. Alternatively, a pair to be provided may be selected at random according to a provision ratio set by the user or set in advance.

The fingering process described above (see FIG. 2)
The fingering may be applied to the entire song, or the entire song may be divided into a plurality of phrases in advance, and the fingering may be applied to each phrase. Since it is rare that a single song can be fingered at one position, it is efficient and preferable to divide the song into a plurality of phrases in advance and perform fingering for each phrase. In such a case, any method of dividing the phrase may be used. For example, there are various types of methods such as manual division in which division is performed at an appropriate position based on a user's specification, automatic division in which division is performed at an appropriate position according to a predetermined algorithm, and the like. May be something. Further, in the fingering processing (see FIG. 2) described above, fingering is performed with priority given to continuation of the same position. However, fingering may be given priority with continuation of identical strings. When fingering is to be performed with priority given to the same string, the string to be selected may be limited to perform fingering processing. Although the fingering of a cello is shown as an example in the above-described embodiment, it goes without saying that the present invention may be applied to other musical instruments.
For example, in the case of a guitar, there are standard fingering by chords, so by referring to a table showing the standard fingering for each chord, it is possible to realize fingering more like a guitar. Become.

In the above-described embodiment, fingering is performed by using different fingers for consecutive notes. However, if the continuity of the position is interrupted, this portion is used. May cause a large position shift. Therefore, when the continuity of the position is broken, it may be determined whether or not fingering is possible by shifting the finger. When fingering consecutive notes with the same finger, that is, if it is possible to shift the position while holding down the finger, fingering can be applied so as not to cause large position movement Become.

When the performance data processing apparatus is applied to an electronic musical instrument, the electronic musical instrument is not limited to a keyboard instrument, but may be a string instrument, a wind instrument, or a percussion instrument. The sound source device, the performance data processing device, and the like are not limited to those built in one electronic musical instrument main body, but each device may be separately configured and connected to each other using communication means such as a MIDI interface or various networks. It goes without saying that the present invention can be similarly applied to the configured one. Further, the configuration may be a configuration of a personal computer and application software. In this case, the processing program may be supplied from a storage medium such as a magnetic disk, an optical disk, or a semiconductor memory, or may be supplied via a network. Further, the present invention may be applied to an automatic performance device such as a karaoke device or an automatic performance piano, a game device, a portable communication terminal such as a mobile phone, or the like. When applied to a portable communication terminal, not only when the specified function is completed only with the terminal, but also a part of the function is provided on the server side, and the specified function is realized as the whole system consisting of the terminal and the server You may make it.

Note that the format of performance data to be automatically added when fingering information or facial expression information is automatically given is “event + absolute time” in which the event occurrence time is represented by the absolute time in a song or bar. In the event format, the event occurrence time is represented by the time from the previous event in the "event + relative time" format, and the performance data is represented by the pitch and note length of the note or the rest and rest length "Pitch (rest) + note length" format, a "solid system" format in which a memory area is secured for each minimum resolution of performance and events are stored in a memory area corresponding to the time when a performance event occurs And any other form. The processing method of the generated performance data at the time of automatic performance is a method of changing the processing cycle according to the set tempo, and the processing cycle is constant, and the method of counting the timing data in the performance data in one processing is determined by the tempo. Any method may be used, such as a method of changing according to the conditions. When performance data for a plurality of channels exists, a format in which data of a plurality of channels are mixed may be used, or a format in which data of each channel is separated for each track may be used.

[0043]

According to the present invention, it is possible to perform a continuous operation by performing a simple operation such as processing performance data not only in the forward direction but also in the reverse direction. Musical expressions unique to each instrument can be automatically created, so fingering information that can be played smoothly according to the flow of the song and performance information that applies a unique musical expression to each instrument The effect that data can be efficiently assigned can be obtained. Especially when fingering a stringed instrument whose pitch varies depending on the position where the string is held down, fingering is performed while taking into account the position of the hand to be placed when holding down the string. Therefore, an effect is obtained that continuous fingering that allows smooth operation during performance can be performed.
