Abstract

PROBLEM TO BE SOLVED: To make it possible to display beams so as to enable a player to easily view the beams when the interval of the tones at both ends connected by the beams is small by deciding whether the difference between note head display positions is smaller than a prescribed value or not and setting the inclination of the beams horizontal when the difference between the note head display positions is smaller than the prescribed value. SOLUTION: Whether the number of the stems in groups divided to groups, i.e., the number of the tones to be connected by the beams is two pieces or not is judged (S702). If the number of the tones to be connected by the beams is judged to be two pieces, whether the difference between the note head display positions of the two tones within the group is below '1' or not is judged (S704). The difference between the note head display positions is indicated by a absolute value and attains the value of 'positive' or '0'. When the difference between the note head display positions of the two tones in the group is judged to be below '1', the inclination of the beams is set horizontal (S706). The ruggedness of the dots at the time of displaying the beams with a bit map is eliminated and the beams may be so displayed as to be made easily visible by the player.

A keyboard section 18 for inputting performance information by a performance operation in which an operator presses / releases a desired key; a display device 20 for displaying a musical score by a process described later based on flowcharts shown in FIG. A sound source 22 that generates a tone signal based on the information, an amplifier 24 that amplifies the tone signal generated by the tone source 22, and a speaker 26 that emits the tone signal amplified by the amplifier 24 to a space as a tone. It is connected.

Here, a description will be given of a process of emitting a musical tone in the electronic musical instrument into a space (hereinafter, referred to as a "musical tone generating process"). The CPU 10 reads the performance information stored in the RAM 16 and supplies the read performance information to the sound source 22.
2 generates a tone signal based on the supplied performance information. The tone signal thus generated is emitted as a tone to the space via the amplifier 24 and the speaker 26.

Since the above-described tone generation processing is a conventionally known technique, a detailed description thereof will be omitted.

In this electronic musical instrument, the CPU 10 executes the above-described musical tone generation processing,
Display device 2 based on the performance information read from
0 to display a musical score indicated by the performance information (hereinafter, referred to as a musical score).
This is called “score display processing”. ) Is executed.

Hereinafter, the above-described musical score display processing will be described in detail with reference to a flowchart.

FIG. 3 shows a musical score display processing routine which is a main routine of the musical score display processing. In this musical score display processing routine, first, a staff, a staff, a treble clef, A clef such as a clef, a tonality symbol consisting of sharp and flat, and a time signature are displayed (step S302). This step S302
Is a known technique, and a detailed description thereof will be omitted.

Next, a note display processing routine (FIG. 4), which is a subroutine of the musical score display processing routine, is executed (step S304). This note display processing routine is the processing according to the musical score display method according to the present invention.
Processing for displaying the stem, stem, and beam is executed.

When the execution of the musical note display processing routine is completed, the process returns to the musical score display processing routine, displays bar lines (step S306), and terminates the musical score display processing routine. Note that the processing in step S306 is a conventionally known technique, and a detailed description thereof will be omitted.

FIG. 4 shows a musical note display processing routine. In this musical note display processing routine, first,
The performance information is read from the RAM 16 and time information indicating the sounding timing and sounding time in the performance information is quantized (step S402).

Next, referring to the quantized time information, sounds generated at the same timing are grouped as chords (step S404). In the following description, when it is necessary to distinguish the number of sounds pronounced at the same timing, if there are a plurality of sounds pronounced at the same timing, those sounds are referred to as “chords”, If only one sound is generated at the same timing, the sound is referred to as a “single sound”.

Further, single tones and chords connected by beams are grouped (step S406). In this embodiment, it is assumed that notes within one beat constitute a group.

Next, the display position of the notehead is determined (step S408). That is, a vertical position on a staff notation for displaying noteheads is determined in accordance with the pitch of each sound and the tonality of the music. In addition, the vertical position on the staff for displaying this note head is
Hereinafter, it is referred to as “note head display position”.

Here, as shown in FIG. 5, for example, as shown in FIG. 5, when the clef is a treble clef, C on the lower first line is set to "0", and D Is “1”,
E of the first line is “2”, and B between the upper second is “1”.
As in the case of "3", it is defined by the numbers assigned according to the respective positions with respect to the staff and the addition line.

Therefore, when the note head display position is defined as shown in FIG. 5, the note head display position of the sound shown in FIG. 6A is "4", and the sound shown in FIG. The note head display position is “9”, and the note head display position of the sound in FIG.
Becomes

In order to facilitate understanding of the present invention,
In the following description, note head display positions will be described using those defined in FIG.

Next, the direction of the stem is determined (step S410). In this embodiment, the direction of the stem is determined based on whether or not the notehead display position is the third line, that is, “6” or more. If the notehead display position is less than “6”, the notehead is downward and extends downward from the head.

With respect to the direction of the stem in the case of a chord, for example, the average value of all the note head display positions of the constituent sounds of the chord is calculated, and when the average value is "6" or more, the note head is calculated. If the average value is less than “6”, it is determined to be upward extending from the note head.

After determining the stem direction in step S410, a beam display processing routine (FIGS. 7 and 8) is executed as a subroutine of the note display processing routine (step S412). In this beam display processing routine, as will be described later, the inclination of the beam is determined with reference to the note head display position of the sound forming the tuplet, and the beam is displayed at the determined inclination.

When the execution of the beam display processing routine is completed, the process returns to the note display processing routine, and the stem and the stem are displayed (step S414). Here, only stems are displayed for single tones and chords connected by beams, and for other single tones and chords, stems are displayed together with stems. The processing in step S414 is a conventionally known technique, and a detailed description thereof will be omitted.

Then, the sub-routine of the note display processing routine
As a routine, a note head display processing routine (FIGS. 10 and 11) is executed (step S416). In this note head display processing routine, processing for displaying a note head of a chord is performed.

When the execution of the note head display processing routine is completed, the process returns to the note display processing routine to display the note head of a single note (step S418). Then, the note display processing routine is ended, and the process returns to the musical score display processing routine. The processing in step S418 is a conventionally known technique, and a detailed description thereof will be omitted.

Next, the beam display processing routine will be described with reference to FIGS. 7 and 8. For the sake of easy understanding, in the following description, the processing when all the sounds in the group are single sounds will be described. Shall be explained.

In this beam display processing routine,
First, it is determined whether or not the number of stems in the group grouped in step S406, that is, the number of sounds connected by the beam is two (step S702).

If it is determined in step S702 that the number of stems in the group is two, that is, that the number of sounds connected by the beam is two, the number of stems in the group is two.
It is determined whether or not the difference between the note head display positions of the sounds is equal to or less than "1" (step S704). Note that the difference between the note head display positions is represented by an absolute value, and takes a value of “positive” or “0”.

Here, when it is determined that the difference between the note display positions of the two sounds in the group is equal to or less than "1", the beam inclination is set to be horizontal (step S706).

Therefore, when the pitch between the two sounds connected by the beam is small, that is, the difference between the note display positions of the two sounds connected by the beam is equal to or less than "1", the inclination of the beam is set to be horizontal. Therefore, when the beam is displayed in the bit map, the unevenness of the dots is eliminated, and the beam can be displayed so that the player can easily see it.

On the other hand, when it is determined that the difference between the notehead display positions of the two notes in the group exceeds "1", the difference between the notehead display positions of the two notes in the group is "2". Assuming that there is, the beam inclination is set (step S70)
8). In this case, the inclination of the beam is, for example, the inclination of the beam when connecting the stem of the sound (a) and the stem of the sound (b) in FIG.

Therefore, even if the difference between the note head display positions of two sounds connected by a beam is, for example, "5" or "6", and the pitch of the two sounds connected by the beam is extremely large, The inclination of the beam is set to the inclination when the difference between the notehead display positions of two sounds connected by the beam is “2”, and the steepness of the beam is suppressed. The beam can be displayed so that it is easy to see.

When the processing in step S706 or S708 is completed as described above, the vertical display position of the beam (hereinafter, referred to as "vertical display position").
Is determined (step S710).

Here, when the beam inclination is set to be horizontal in step S706, the shorter one of the two stems has a predetermined length α (for example, a length of one octave in the vertical direction on the staff notation). The vertical display position of the beam is determined so that When the beam inclination is set in step S708 by assuming that the difference between the notehead display positions is “2”, the length of one stem becomes the predetermined length α and the length of the other stem becomes The vertical display position of the beam is determined so that is equal to or longer than a predetermined length α.

Specifically, in the example shown in FIG. 9 (b), the note head display position of the sound (a) is "0".
The notehead display position of the sound (b) is "4" and the difference between the two is "4". In this case, the difference between the notehead display positions is "2" in step S708. As a result, the inclination of the beam is determined. In step S710, the vertical display position of the beam is determined by the inclination of the difference "2" between the note head display positions.
When the two stems face upward as in the example of (b),
As shown in FIG. 9C, the length of the stem of the sound (b) having the larger value of the notehead display position is set to a predetermined length α, and the sound (b) of the sound having the smaller value of the notehead display position is (a). The length of the stem (α
+ Β) to determine the vertical display position of the beam.

In the example shown in FIG. 9D,
The note head display position of the sound (a) is “11”, and
The notehead display position of the sound (b) is “8” and the difference between the two is “3”. In this case, in step S708, the difference between the notehead display positions is “2”. The tilt of the beam will be determined. In step S710, the vertical display position of the beam is determined by the inclination of the difference "2" between the note head display positions.
When the two stems face downward as in the example of (d),
As shown in FIG. 9 (e), the length of the stem of the sound (b) with the smaller value at the notehead display position is set to a predetermined length α, and the sound (a) with the larger value at the notehead display position is set. The length of the stem (α
+ Β) to determine the vertical display position of the beam. When the processing in step S710 is completed, a beam is displayed based on the inclination determined in step S706 or S708 and the vertical display position determined in step S710 (step S71).
2) Return to the note display processing routine. On the other hand, step S
If it is determined in 702 that the number of stems in the group is greater than two, that is, that the number of sounds connected by the beam is three or more, it is determined whether or not the stem is upward ( Step S714).

Here, when it is determined that the stem is upward, the notehead display position of the higher pitched sound at both ends of the beam is the highest sound of the sound other than both ends of the beam. Is determined to be below the notehead display position (step S7).
16).

In step S716, it is determined that the notehead display position of the higher pitch sound at both ends of the beam is equal to or less than the notehead display position of the highest sound other than the both ends of the beam. In this case, the inclination of the beam is set to be horizontal (step S720). That is, when determining the tilt of the beam, for the sound connected by the beam, the display positions of the noteheads of the sounds at both ends thereof are compared with the display positions of the noteheads of other sounds, and according to the result of the comparison. , The tilt of the beam can be set horizontally.

On the other hand, if it is determined that the note head display position of the higher pitch sound at both ends of the beam is not less than the note head display position of the highest sound other than the both ends of the beam. Then, the difference between the note head display positions of the sounds at both ends of the beam is determined (step S718).

If it is determined in step S718 that the difference between the note display positions of the sounds at both ends of the beam is equal to or smaller than "1", the beam inclination is set to be horizontal (step S720).

Accordingly, when the difference between the note head display positions of the sounds at both ends connected by the beam is equal to or less than "1", that is, when the pitch at the sounds at both ends connected by the beam is small, the inclination of the beam is set to be horizontal. Therefore, when the beam is displayed in the bit map, the unevenness of the dots is eliminated, and the beam can be displayed so that the player can easily see it.

If it is determined in step S718 that the difference between the note head display positions of the sounds at both ends of the beam is “4” or more, it is determined that the difference between the note head display positions is “4”. Considering that, the beam inclination is set (step S7)
22).

Therefore, even if the difference between the note head display positions of the sounds at both ends connected by the beam is, for example, "5" or "6", and the pitch of the sounds at both ends connected by the beam is extremely large, The inclination of the beam is set to the inclination when the difference between the note display positions of the sounds at both ends connected by the beam is “4”, and the steepness of the beam is suppressed. The beam can be displayed so that it is easy to see.

Further, when it is determined in step S718 that the difference between the note head display positions of the sounds at both ends of the beam is neither "1" nor less than "4", the difference between the note head display positions is determined. The inclination of the beam is set accordingly (step S724).

On the other hand, if it is determined in step S714 that the stem is downward, the note head display position of the lower pitch sound at both ends of the beam is set to the lowest position of the sound other than both ends of the beam. It is determined whether or not the sound is at or above the note head display position of the sound (step S726).

In step S726, it is determined that the notehead display position of the lower pitch sound at both ends of the beam is equal to or greater than the notehead display position of the lowest sound other than the ends of the beam. In this case, the inclination of the beam is set to be horizontal (step S730). That is, when determining the tilt of the beam, for the sound connected by the beam, the display positions of the noteheads of the sounds at both ends thereof are compared with the display positions of the noteheads of other sounds, and according to the result of the comparison. , The tilt of the beam can be set horizontally.

On the other hand, if it is determined that the notehead display position of the lower pitch sound at both ends of the beam is not greater than the notehead display position of the lowest sound other than the ends of the beam. Then, the difference between the note display positions of the sounds at both ends of the beam is determined (step S728).

If it is determined in step S728 that the difference between the note display positions of the sounds at both ends of the beam is equal to or less than "1", the beam inclination is set to be horizontal (step S730).

Accordingly, if the difference between the note head display positions of the sounds at both ends connected by the beam is less than or equal to "1", that is, if the pitch of the sounds at both ends connected by the beam is small, the inclination of the beam is set to be horizontal. Therefore, when the beam is displayed in the bit map, the unevenness of the dots is eliminated, and the beam can be displayed so that the player can easily see it.

If it is determined in step S728 that the difference between the note head display positions of the sounds at both ends of the beam is "4" or more, it is determined that the difference between the note head display positions is "4". Considering that, the beam inclination is set (step S7)
32).

Therefore, even if the difference between the note head display positions of the sounds at both ends connected by the beam is, for example, “5” or “6”, and the pitch of the sounds at both ends connected by the beam is extremely large, The inclination of the beam is set to the inclination when the difference between the note display positions of the sounds at both ends connected by the beam is “4”, and the steepness of the beam is suppressed. The beam can be displayed so that it is easy to see.

Further, in step S728, when it is determined that the difference between the note head display positions of the sounds at both ends of the beam is neither "1" nor less than "4", the difference between the note head display positions is determined. The inclination of the beam is set accordingly (step S734).

As described above, steps S720, S722, S724, S730,
When the processing in step S732 or step S734 is completed, the vertical display position of the beam is determined (step S736).

Here, in determining the vertical display position of the beam, the vertical display position of the beam is determined so that the shortest stem of the stems in the group has a predetermined length α.

Specifically, in the example shown in FIG. 9F, regarding the sounds (a) to (2) in the group,
The note head display position of the note (a) is "2", the note head display position of the note (b) is "4", and the note head display position of the note (c) is "5". , (D) is “4”, so in the beam display processing routine, the process proceeds to “step S702 → step S714 → step S716 → step S720” and proceeds to step S72.
At 0, the tilt of the beam is set horizontal. With this beam tilt, if the length of the stem of the higher (2) sound at both ends in the group is connected to the beam with the predetermined length α,
The length of the stem of the sound of (c) becomes equal to or less than the predetermined length α, and becomes the shortest in the group. Accordingly, as shown in FIG. 9 (g), the length of the shortest stem of the sound (c) is a predetermined length α.
The vertical display position of the beam is determined by extending the stems of the sounds (a), (b) and (d) so that

In the example shown in FIG. 9 (h), regarding the sounds (a) to (2) in the group, the note head display position of the sound (a) is “2”, and The note head display position of the sound is “4”, and the note head display position of the sound (c) is “4”.
Since the notehead display position of the sound (d) is “5”, in the beam display processing routine, “step S
702 → step S714 → step S716 → step S718 → step S724 ”and step S7
At 24, the inclination of the beam is determined according to the difference “3” between the notehead display position “2” of the sound (a) and the notehead display position “5” of the sound (d) in FIG. The inclination is set as shown by the broken line above. If the length of the stems of the sounds (a) and (d) at both ends in the group are connected by a beam with a predetermined length α by the inclination of the beam, the length of the stem of the sound (b) becomes a predetermined length. It is shorter than the length α, and becomes the shortest in the group. Accordingly, as shown in FIG. 9 (i), the stems of the sounds (a), (c) and (d) are extended so that the length of the shortest stem of the sound (b) becomes a predetermined length α. In this way, the vertical display position of the beam is determined.

When the processing of step S736 is completed, steps S720, S722, S72
4. The inclination determined in step S730, step S732 or step S734, and step S73.
The beam is displayed based on the vertical display position determined in step 6 (step S738), and the process returns to the note display routine.

The beam display processing routine described above relates to the processing when all the sounds in the group are single tones, as described above, and the processing when the sounds in the group include chords. Is omitted. However, if the sound in the group contains a chord, it is determined whether the stem of the chord in the group is upward or downward, and if the stem is upward, the highest of each chord in the group is determined. The beam display processing routine described above is executed for the sound, and when the stem is directed downward, the beam display processing routine described above is executed for the lowest tone of each chord in the group, so that the beam display processing routine described above is left as it is. Can be used.

Next, a notehead display processing routine will be described with reference to FIGS. As described above, in this notehead display processing routine, processing for displaying a notehead of a chord is executed. First, it is determined whether the stem of the chord to be processed is upward or downward. (Step S1002).

If it is determined that the stem is downward, "1" is set to a variable i used in this notehead display processing routine (step S1004).

Then, among the sounds constituting the chord (hereinafter, referred to as “chord constituent sounds”), the note head display position of the i-th sound from the treble side is obtained (step S 1006). The note head display position of the (i + 1) th sound is obtained (step S1008). Next, step S1006
It is determined whether or not the difference between the note display positions of the two sounds acquired in step S1008 and step S1008 is “1” (step S1010).

If it is determined that the difference between the note display positions of the two sounds is "1", the note head of the i-th sound from the treble side is displayed on the right side of the stem (step S1). S10
12) Further, the notehead of the (i + 1) th note from the treble side is displayed on the left side of the stem (step S1014), and then the variable i is incremented by "2" (step S1).
016).

On the other hand, when it is determined that the difference between the note head display positions of the two sounds is not "1", the note head of the i-th sound from the treble side is displayed on the right side of the stem (step S101).
8) Then, the variable i is incremented by "1" (step S1020).

Step S1016 or step S1
When the process of step 020 is completed, it is determined whether or not the (i + 1) th sound from the treble side exists in the chord to be processed (step S1022).

Here, if it is determined that the (i + 1) th sound from the treble side is present in the chord to be processed, the process returns to step S1006 and repeats the processing from step S1006.

On the other hand, if it is determined that the (i + 1) th sound from the treble side does not exist in the chord to be processed, it is determined whether or not the i-th sound from the treble side exists in the chord to be processed. Is determined (step S1024).

If it is determined that the i-th note from the treble side exists in the chord to be processed, the notehead of the i-th note from the treble side is displayed on the right side of the stem (step S1). S1026), and returns to the note display processing routine.

On the other hand, if it is determined that the i-th sound from the high note side does not exist in the chord to be processed, the process directly returns to the note display routine.

If it is determined in step S1002 that the stem is upward, the variable i used in this notehead display processing routine is set to "1" (step S1028).

Then, the note head display position of the i-th note from the low note side of the chord constituent tones is obtained (step S103).
0), and obtains the note head display position of the (i + 1) th sound from the lower note side (step S1032).

Next, step S1030 and step S1

36) Further, the notehead of the (i + 1) th note from the bass side is displayed on the right side of the stem (step S1038), and then the variable i is incremented by "2" (step S1).
040).

On the other hand, if it is determined that the difference between the note display positions of the two sounds is not "1", the note head of the i-th sound from the low note side is displayed on the left side of the stem (step S104).
2) Then, the variable i is incremented by "1" (step S1044).

Step S1040 or step S1
Upon completion of the process of 044, it is determined whether or not the (i + 1) th sound from the bass side exists in the chord to be processed (step S1046).

Here, if it is determined that the (i + 1) th sound from the low note side exists in the chord to be processed, the process returns to step S1030, and the processes from step S1030 and on are repeated.

On the other hand, when it is determined that the (i + 1) th sound from the bass side does not exist in the chord to be processed, it is determined whether or not the i-th sound from the bass side exists in the chord to be processed. Is determined (step S1048).

If it is determined that the i-th note from the low note side is present in the chord to be processed, the notehead of the i-th note from the low note side is displayed on the left side of the stem (step S1050), and returns to the note display routine.

On the other hand, when it is determined that the i-th sound from the low note side does not exist in the chord to be processed, the process directly returns to the note display routine.

Next, an example of note head display executed by the note head display processing routine will be described with reference to FIGS. 12 (a) and 12 (b).

Here, FIG. 12A shows the constituent tones of the chord to be processed in the notehead display processing routine. That is, the chords to be processed by the notehead display processing routine include, as constituent sounds, a sound (a) having a notehead display position of "7" and a sound (b) having a notehead display position of "10". It is assumed that a note (c) having a notehead display position of “11” and a sound (d) having a notehead display position of “13” are provided, and these (a) to (d) are performed by the notehead display processing routine. ) Are displayed together with one stem. Note that the note lengths of the chords to be processed are quarter notes.

When the notehead display processing routine is started, first, the stem is determined to be downward with reference to the direction of the stem determined in step S410 (step S410).
1002).

Then, the variable i is set to "1" (step S1004), and the note head display position "13" of the first sound (d) from the treble side is acquired (step S1006). The note head display position "11" of the sound (c) which is the second sound from the side is acquired (step S100).
8).

Here, if it is determined whether the difference between the note head display position "13" and the note head display position "11" is "1" (step S1010), the difference becomes "13-11 = 2". Since it is not "1", the notehead of the sound (d), which is the first sound from the treble side, is displayed on the right side of the stem (step S1018).

Then, "2" is set to the variable i (step S1020), and it is determined whether or not the third sound from the treble side exists (step S1022).
Since the th sound exists, the process returns to step S1006.

Then, the note head display position "11" of the sound (c) which is the second sound from the treble side is obtained (step S1006), and the sound (b) which is the third sound from the treble side is obtained. The note head display position “10” is obtained (Step S100)
8).

Here, if it is determined whether the difference between the note head display position "11" and the note head display position "10" is "1" (step S1010), the difference becomes "11-10 = 1" and "11-10 = 1". "1", which is the second sound from the treble side (c)
Is displayed on the right side of the stem (step S101).
2) The notehead of the third sound (b) from the treble side is displayed on the left side of the stem (step S1014).

Then, "4" is set to the variable i (step S1016), and it is determined whether or not the fifth sound from the treble side exists (step S1022).
Since the fourth sound does not exist, it is determined whether the fourth sound from the treble side exists (step S1024).

Here, since the fourth sound from the treble side exists, the notehead of the sound (a), which is the fourth sound from the treble side, is displayed on the right side of the stem (step S1026), and the notehead is displayed. The processing routine ends.

When the note head display processing routine is executed as described above, chords are displayed on the staff notation as shown in FIG.

In the above-described embodiment, when the number of stems in the group is determined to be two in the beam display processing routine, that is, the number of sounds connected by the beam is determined to be two, Determines whether the difference between the notehead display positions of the two tones in the group is equal to or less than "1" (step S704), and the difference between the notehead display positions of the two tones in the group is "1". If it is determined to be less than the above, the inclination of the beam is set horizontal (step S706), and if it is determined that the difference between the note display positions of the two sounds in the group exceeds "1", Then, the difference between the note display positions of the two tones in the group is regarded as "2", and the beam inclination is set (step S708). However, without being limited to this, similar to the processing in steps S718 to S724, for example, when it is determined that the difference between the notehead display positions of the two sounds in the group is “1” or less, , The tilt of the beam is set horizontal, and the difference between the note display positions of the two notes in the group is “4”
If it is determined that the difference is above, it is considered that the difference between the note head display positions is “4”, and the inclination of the beam is set.
If the difference between the notehead display positions of the two tones in the group is neither "1" nor less than "4", the beam inclination may be set according to the difference between the notehead display positions. Good.

Regarding the determination of the tilt of the beam, in addition to the above-described embodiment, several angles indicating the tilt that can beautifully display the beam are prepared in advance, and a desired angle is selected from the prepared angles. Of course, it is also possible to select one.

[0103]

As described above, according to the score displaying method of the present invention, even if the pitch of the sound connected at both ends of the beam is small or the pitch is large, the beam is displayed so that the player can easily see it. It has an excellent effect that it can be displayed.
