Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a musical score display control device and a musical score display processing program.

[0002]

2. Description of the Related Art In a performance training device for guiding the performance of music data, a musical score image of the music data is displayed on a display device such as an LCD, and an image of a note to be played is emphasized or displayed. As the notes to be played are moved, they are moved to guide the performance. Further, in a normal performance device, by displaying the score image while reproducing the model song data stored in the memory or the like, the relationship between the musical tone to be pronounced and the displayed score is grasped to improve the performance technique. You can also plan. Therefore, a musical score display control device has been proposed which displays corresponding musical notes, chords, and other musical score images as the music data is reproduced.

[0003]

However, in the conventional technique, the user often cannot recognize the key signature of the displayed musical score image when transposing to another key in the middle of the music. Not only images of notes but also images of rests, symbols indicating sound intensity, slur symbols, staccato symbols, chord symbols, etc., are displayed in the score image. Can be recognized, but often miss the key signature in the middle. If it is not possible to recognize that a song has been transposed, there is a problem in that it will be a great obstacle to understanding the performance guide of the song data and the relationship between the musical tone to be pronounced and the score.

Further, in the prior art, the process of converting the music data into a score image and displaying the score image is a heavy load to the control means such as the CPU of the apparatus, and therefore, during the image processing of the score image It's difficult to work.
For this reason, for example, when a user's performance is performed during that time, there is a problem that the performance operation cannot be supported and sound generation is delayed.

A first object of the present invention is to allow a user to sufficiently recognize that a key is displayed in a musical score image by transposing to another key in the middle of a song. A second object of the present invention is to prevent the sound processing from being disturbed due to the image processing of the score image.

[0006]

If the key signature is not detected in any of the measures in any of the specified number of measures by the first step, the score image corresponding to the first measure to the last measure of the specified number of measures is displayed by a predetermined display means (implementation). In a form, it is collectively displayed in a predetermined range (corresponding to the display unit 5 in FIG. 1) of a screen (corresponding to the upper and lower areas of the VRAM in FIGS. 9 to 12 in the embodiment), and is predetermined. When a key signature is detected in an arbitrary measure of the number of measures by the first step, the score image corresponding to the measure from the first measure of the predetermined measure to the bar immediately before the measure having the key measure is in a predetermined range. To display all at once The second step of collectively displaying the score images corresponding to the bar with the key signature and the subsequent bars in a predetermined range, and when the reproduction of the music data corresponding to the score images displayed in the predetermined range is completed. Has a third step of instructing the second step to display the score image corresponding to the music data to be reproduced next with the score image relating to the reproduction end. In this case, the predetermined range on the screen of the display means is composed of a plurality of stages (in the embodiment, two stages consisting of an upper stage and a lower stage) of display regions arranged in the vertical direction of the screen, and the third step is reproduction of music data. When the reproduction of the song data corresponding to the score image displayed at the top is completed, the score image corresponding to the song data to be reproduced next to the song data corresponding to the latest score image displayed at the bottom May be instructed to the second step so as to be displayed instead of the score image displayed at the top. Further, as in the musical score display processing program according to claim 6, there is further provided a fourth step of executing the musical tone generation processing in response to an input of a musical tone generation command from the outside. The configuration may be such that the processes of the first, second, and third steps are executed during the time period when the generation process is not executed.

According to the invention of claim 1 or claim 4, if there is no key for instructing transposition to any measure in any predetermined number of measures of two measures or more, the predetermined number of measures The score images corresponding to the first measure to the last measure are collectively displayed, and if there is a key signature in an arbitrary measure of a predetermined number of measures, the bar having the key signature from the first measure of the predetermined number of measures is displayed. The score images corresponding to the preceding bar are collectively displayed, and the score images corresponding to the bar having the key signature and the subsequent bars are collectively displayed. When the reproduction of the music data corresponding to the displayed score image is completed, the score image is changed to the score image corresponding to the music data to be reproduced next. Further, according to the invention described in claim 3 or 6, the musical score displaying process is executed in the time zone in which the musical tone generating process is not executed in response to the input of the musical tone generating command from the outside.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a musical score display control device according to the present invention will be described below with reference to the drawings. Figure 1
FIG. 1 is a block diagram showing a configuration of a score display control device in an embodiment. In FIG. 1, a CPU 1 has a program ROM 3, a work RAM 4 and a system RAM 2 via a system bus 2.
It is connected to the display unit 5, the music memory 6, the keyboard 7, the switch unit 8, the sound source 9, and the VRAM 10, and sends and receives commands and data to and from these units to control the entire apparatus. Further, the sound source 9 is connected to a sounding circuit 11 including a D / A converter, an amplifier, a speaker and the like.

The program ROM 3 stores a music score display program and initial data at initialization when the power is turned on. Work RAM 4 is CPU
1 temporarily stores various data processed by 1. The display unit 5 displays the score image corresponding to the music data. The song memory 6 stores a plurality of song data. The structure of the music data will be described later. Keyboard 7 is
The performance data is input to the CPU 1 in response to a performance operation. The switch unit 8 is composed of a plurality of switches, and inputs commands and data to the CPU 1 according to the operation thereof.
The tone generator 9 sends musical tone waveform data generated in accordance with the performance data input by the performance operation on the keyboard 7 to the sounding circuit 10 for sounding. Further, the reproduction data of the music read from the music memory 6 is adjusted in volume in accordance with the volume operation of the switch unit 18 and is sent to the sound generation circuit 11 to generate a sound. The VRAM 10 expands and stores the image data to be displayed on the display unit 5 into a bitmap for one screen, and sends the image data to the display unit 5 for display at a predetermined display timing.

FIG. 2 shows the structure of the storage area of the VRAM 10, a partial area of the work RAM 4, and the music data stored in the music memory 6. VRAM10
Stores an upper image and a lower image to be displayed in the upper region and the lower region of the screen of the display unit 5, respectively.
The image data in each stage has an area for storing images of a staff and a treble clef, which are backgrounds (BG) that do not change regardless of music data, and an area for storing musical score images that change for each music data. The areas of RAMA and RAMB, which are part of the work RAM 4, are areas for temporarily storing the images developed into the upper image and the lower image, respectively.

The music data stored in the music memory 6 is composed of a plurality of measures (1) to (n), and the end of each measure is bar line data. First measure of song data (1)
In, there is usually a plurality of note data following the key signature data of the song and the chord data of the measure. In addition, rest data may be included as in bar (2). Further, although not shown in the figure, data such as key signatures in the case of transposing, symbols representing the strength of sound, slur symbols, staccato symbols, etc. are appropriately included.

Next, regarding the operation of the musical score display processing in the musical score display control device of FIG. 1, flowcharts of the CPU 1 shown in FIGS. 3 to 8 and 13 to 17, song data shown in FIGS. 9 to 12, work RAM. Will be described with reference to a diagram showing the relationship between the area of FIG. Figure 3
Is a main flow, and after a predetermined initialization (step A1), it is determined whether or not a predetermined timing is reached (step A2). When this timing is reached,
Musical instrument processing is executed (step A3). On the other hand, in a time zone where this timing has not been reached, it is determined whether or not a flag GF described later is "1" (step A4). If GF is "1", the score display generation process is executed (step A5). If GF is not "1", the process returns to step A2. After the musical instrument processing or the musical score display generation processing, the process returns to step A2 to determine whether or not a predetermined timing has been reached. As shown in FIG. 4, the musical instrument process of step A3 includes a switch process (step B1), a reproduction process (step B2), a keyboard process (step B3), and other processes (step B4).

FIGS. 5 and 6 are flow charts of the switch processing in step B1 of FIG. First, it is determined whether or not the start switch is turned on (step C1), and if this switch is not turned on, it is determined whether or not another switch is turned on (step C2). When another switch is turned on, another process corresponding to the switch is performed (step C3), and the process returns to the flow of FIG. On the other hand, when the start switch is turned on, the start flag STF is inverted (step C4). And ST
It is determined whether or not the value of F is "1 (reproduction)" (step C5). If STF is "1", the initial score display processing is executed (step C6).

Next, the start address of the music data is set in the address register AD and "1" is set in the variable D (step C7). The variable D is a register for setting the bar number of the bar currently read by reproducing the music data. After that, it is determined whether or not the music data (AD) designated by AD is a key signature (step C).
8). If the song data (AD) is a key signature, the key signature is stored in the register KEY (step C9). Next, AD is incremented (step C10), and it is determined whether the song data (AD) is a chord (step C11). If it is a code, code processing is executed (step C12). In step C5, S
If the TF is "0 (reproduction stopped)", mute processing is performed (step C13), the score display is erased (step C14), and the process returns to the flow of FIG.

Song data (AD) in step C11
If is not a chord, it is determined in the flow of FIG. 6 whether the music data (AD) is a rest (step C15). If it is a rest, the rest length is stored in the register TIME (step C16). Then, the process returns to the flow of FIG. If the song data (AD) is not a rest in step C15, it is determined whether the song data (AD) is a note (step C17). If it is a note, its pitch is stored in the register NOTE (step C18). Next, based on the key signature of KEY, N
The pitch of OTE is converted (step C19), and a sounding instruction is given to the sound source 9 (step C20). Then, the note length, that is, the pronunciation time is stored in TIME (step C2
1) and returns to the flow of FIG. If the music data (AD) is not a note in step C17, other processing is performed and the process returns to the flow of FIG.

7 and 8 are flowcharts of the initial score generation processing in step C6 of FIG. In this process,
This is a process of displaying the first musical score before the music is played when the start switch is turned on. In this flow, the work RAM area RAMA and RAM
Bar number of image data stored in B, bar number of image data stored in upper and lower areas of VRAM,
And the values of various variables A, B, C, E, F (measure number)
9 to FIG. 12 show how the music data changes according to the contents of bars 1, 2, 3, and 4 of the music data (whether or not there is a key signature). In this case, the variable A is a pointer that specifies the bar number of the inflection data. The variable B indicates the bar number next to the bar number of the last bar displayed in the upper part of the display section. Variable C
Indicates the bar number next to the bar number of the last bar displayed in the lower part of the display section. The variable E is stored in the RAMA and indicates the bar number of the bar which has been converted into the score data. The variable F is stored in the RAMB and indicates the bar number of the bar which has been converted into the score data.

In FIG. 7, first, "1" is set in A (step D1). That is, set the first measure number of the song. Then, it is determined whether or not the next bar (A + 1) has a key signature for instructing a key change (step D2). If the bar has a key signature, the next bar (A
It is determined whether or not there is a key signature instructing the key modulation in (+2) (step D3). If this measure (A + 2) has a key signature, the measure (A) is converted into musical score data (step D
4), store in RAMA (step D5). Also,
Convert measure (A + 1) to score data (step D
6), store in RAMB (step D7). Then, the value of A + 1 is stored in variables E and B, and A + 2 is stored in A.
The value of is stored (step D8).

The composition of the music data in this case is shown in FIG.
As shown in. Here, the bar marked with "○" is a bar with a key signature. It is assumed that the first measure 1 of the music data always has a key signature. That is, the bar 1 is marked with “◯” including the music data in C major and C minor. When there is a key signature in the second and subsequent measures, the basic key of the song is transposed to another key. That is, the key signatures of the second and subsequent measures indicate the transposition. This also applies to FIGS. 10 to 12 described later. Therefore, in the case of the music data of FIG. 9A, there are key signatures in measures 2 and 3. In this case, the image data of bar 1 is stored in the area of RAMA and the image data of bar 2 is stored in the area of RAMB by the processing of steps D5 and D7. Further, by the processing of step D8, the values of "3", "2", and "2" are stored in the variables A, B, and E of FIG. 9D, respectively.

When there is no key signature in the measure (A + 1) in step D3, the measure (A) is converted into musical score data (step D9) and stored in RAMA (step D).
10). Also, the measures (A + 1) and (A + 2) are converted into musical score data (step D11) and stored in the RAMB (step D12). And A + 1 for variables E and B
And the value of A + 3 is stored in A (step D13). In this case, in the music data shown in FIG. 10A, the bar 2 marked with "O" has a key signature, and the bar 3 marked with "X" has no key signature. In this case, step D
By the processing of 16 and D18, the RAM of FIG.
Image data of measure 1 is stored in area A
In the area B, the image data for two measures of measures 2 and 3 is stored. By the process of step D19, the values of "4", "2", and "2" are stored in the variables A, B, and E of FIG. 10 (d), respectively.

When there is no key signature in the measure (A + 1) in step D2, the measure (A +) is added in the flow of FIG.
It is determined whether or not there is a key signature instructing a key change in 2) (step D14a). If the bar has a key signature, it is further determined whether or not the bar (A + 3) has a key signature for instructing transposition (step D14b). If the measure has a key signature, the measures (A) and (A + 1) are converted into musical score data (step D15) and stored in RAMA (step D16). Also, the measure (A + 2) is converted into musical score data (step D17) and stored in the RAMB (step D18). Then, the value of A + 2 is stored in the variables E and B, and the value of A + 3 is stored in A (step D19). In this case, in the music data of FIG. 11 (a), there are key signatures in measures 3 and 4 marked with "○",
There is no key signature in bar 2 marked with "x". In this case,
By the processing of steps D16 and D18, FIG.
The image data of two measures of bar 1 and bar 2 is stored in the area of RAMA in (b), and the image data of bar 3 is stored in the area of RAMB. In addition, step D19
By the processing of, the variables A, B, and E in FIG.
Values of “4”, “3”, and “3” are stored respectively.

In step D14a, the measure (A + 2)
If there is no key signature in, it is determined whether or not there is a key signature instructing transposition in the measure (A + 3) (step D20a).
If this measure has no key signature, measures (A) and (A +
1) is converted into musical score data (step D20b), and RA
Store in MA (step D21). Also, measure (A
+2) and (A + 3) are converted into musical score data (step D22) and stored in RAMB (step D23).
Then, the values of A + 2 are stored in variables E and B, and A is set to A
The value of +4 is stored (step D24). In this case, there is no key signature in bar 2, bar 3 and bar 4 marked with "x" in the music data of FIG. In this case, the processing of steps D21 and D23 is performed as shown in FIG.
The image data for two measures of measure 1 and measure 2 is stored in the RAMA area of (b), and the image data for two measures of measure 3 and measure 4 is stored in the area of RAMB.
Further, by the processing of step D24, the variables A, B, and E in FIG. 12D are set to "5", "3", and "3", respectively.
The value of is stored.

In step D14b, measures (A +
When there is no key signature in 3), the music data has a key signature in bar 3, and bars 2 and 4 have no key signature. In this case, the process proceeds to step D20b and the processes up to D24 are performed. Therefore, by the processing of steps D21 and D23, 2 of bar 1 and bar 2 are added to the area of RAMA.
The image data for a bar is stored, and the image data for two bars, bar 3 and bar 4, is stored in the RAMB area. Further, the variable A,
The values of "5", "3", and "3" are stored in B and E, respectively.

In step D20a, measures (A +
When there is a key signature in 3), the music data has a key signature in bar 4, and bars 2 and 3 have no key signature. In this case, the process proceeds to step D15 and the processes up to step D19 are performed. Therefore, steps D16 and D1
By the process of 8, the image data of two measures of the measure 1 and the measure 2 is stored in the area of RAMA, and the image data of the measure 3 is stored in the area of RAMB. In addition, the values of “4”, “3”, and “3” are stored in the variables A, B, and E, respectively, by the processing of step D19.

Steps D8, D13, D19 or D24
In, the bar numbers are stored in variables E and B, and variable A
After updating the measure number of, the measure number of the variable A is stored in the variables F and C in step D25 of FIG. 8 (step D25). Therefore, as shown in (d) of FIGS. 9 to 12, the values of A are stored in the variables C and F. Next, the image data of RAMA and RAMB is VR
Transfer to AM (step D26). And VRAM
The cursor is displayed at the first note of the musical score image developed in step S27 (step D27). Thereafter, the flag GF is set to "0 (display end)" and the flag AF is set to "1 (upper)" (step D28), and the process returns to the flow of FIG. 5 and proceeds to step C7. Therefore, as shown in (c) of FIGS. 9 to 12, the data of the musical score images of the bars corresponding to the upper and lower stages of the VRAM are stored and displayed on the display unit.

13 to 15 are flowcharts of the reproduction process of step B2 in the musical instrument process flow of FIG. In FIG. 13, it is determined whether or not the STF value is "1 (reproduction)" (step E1). If this value is "1", it is determined whether or not a predetermined minimum time has elapsed. It is determined (step E2). When the minimum time has elapsed, TIM
The value of E is decremented (step E3). And
It is determined whether or not the value of TIME has reached "0" (step E4). If this value has not reached “0”, or if the STF value is “0 (stop playback)” in step E1, or if the minimum time has not yet elapsed in step E2, this flow To finish.

When the value of TIME reaches "0" in step E4, the value of AD, that is, the address of the music data is incremented (step E5). Then, it is determined whether or not the music data (AD) which is the music data designated by AD has no data (step E6).
When there is no data, both the flags GF and STF are returned to "0" (step E7), the sound source 9 is instructed to mute (step E8), and the display is erased (step E9). Then, the process returns to the flow of FIG. Step E
If the music data (AD) is not present in No. 6, it is determined in the flow of FIG. 14 whether the music data (AD) is a key signature (step E10). If the song data (AD) is a key signature, the key signature is stored in the register KEY (step E11). Song data (A
If D) is not a key signature, it is determined whether or not the music data (AD) is a chord (step E12). If it is a code, code processing is executed (step E1).
3).

If the song data (AD) is not a chord, it is determined whether the song data (AD) is a bar line (step E14). If it is a bar line, the value of the variable D that stores the bar number of the bar currently read by reproduction is incremented (step E1).
5). Then, it is determined whether or not the measure number of the variable D and the measure number of the variable B match (step E16). That is, it is determined whether or not the bar number of the bar currently read by reproduction and the bar number of the last bar displayed in the upper part of the screen of the display unit 5 match. In other words, it is determined whether or not the reproduction of the music data corresponding to the score image displayed in the upper part of the screen has ended. Variable D
If the measure number of and the measure number of variable B match,
The contents of RAMA are transferred to the upper stage of VRAM (step E17). Then, the measure number of the variable E is stored in the variable B (step E18). Also, GF indicating that the score conversion process for the next bar is necessary is set to "1 (display change)" (step E19). After that, the process returns to step E5 of FIG. 13 and AD is incremented to specify the next music data (AD).

At step E16, if the measure number of the variable D and the measure number of the variable B do not match, the variable D
It is determined whether or not the measure number of (1) and the measure number of the variable C match (step E20). That is, it is determined whether or not the bar number of the bar currently read by reproduction and the final bar number displayed in the lower part of the screen of the display unit 5 match. In other words, it is determined whether or not the reproduction of the music data corresponding to the score image displayed in the lower part of the screen has ended. When the measure number of the variable D and the measure number of the variable C match, the contents of the RAMB are set to VRAM.
To the lower stage (step E21). And the variable F
The measure number of is stored in the variable C (step E18).
As a result, it is necessary to convert the next measure into the score, so GF is set to "1 (display change)" (step E19). After that, the process returns to step E5 of FIG. 13 and AD is incremented to specify the next music data (AD).

When the music data (AD) is not a bar line in step E14 of FIG. 14, it is determined in the flow of FIG. 15 whether the music data (AD) is a rest (step E23). If it is a rest, the sound source 9 is instructed to mute (step E24), and the rest length is stored in the register TIME (step E25). Then, the process returns to the flow of FIG. If the song data (AD) is not a rest at step E23, the song data (AD)
Is a note (step E26). If it is a note, its pitch is stored in the register NOTE (step E27). Next, the pitch of NOTE is converted based on the key signature of KEY (step E28), and the sound source 9 is instructed to sound (step E29). Then, the note length, that is, the pronunciation time is stored in TIME (step E30), and the cursor is moved to the corresponding note (step E31). Then, the process returns to the flow of FIG. Step E
If the song data (AD) at 26 is not a note,
Other processing is performed, and the process returns to the flow of FIG.

16 and 17 are flowcharts of the musical score display generation processing in the main flow of FIG. In FIG. 16, it is determined whether or not the value of the flag PF is "0" (step F1). The PF is a flag that is set to "1" when the process of converting the music data into the musical score data is started, and is returned to "0" when the conversion is completed. The initial value, that is, the beginning of music data, has a PF value of "0". When the value of PF is "0", it is determined whether or not there is data in the bar (A) designated by the variable A (initial value is "1") (step F2). If there is data, it is judged whether or not there is data in the next bar (A + 1) (step F3). If there is data, it is further determined whether or not there is a key signature for instructing a transposition in this same bar (A + 1) (step F4). If there is no data in measure (A + 1) or if there is a key signature in measure (A + 1), the value of flag KF is set to "1" (step F5), and the value of flag PF is set to "1". (Step F6). If there is no key signature in measure (A + 1), only the value of PF is set to "1" in step F6. After setting the value of PF to "1" in step F6, or in step F
If the PF is "1" in step 1, it is determined whether the KF value is "0" (step F7).

When the value of KF is "0", there is data in the measure (A + 1) and there is no key signature.
In this case, the measure (A) and the measure (A + 1) are connected and displayed in the same row. On the other hand, when the KF value is “1”, it means that there is no data in the measure (A + 1) or there is a key signature in the measure (A + 1). In this case,
The measure (A) and the measure (A + 1) are displayed in different columns. When the value of KF is "0" in step F7, it is determined whether or not the value of the flag AF is "1 (upper display)" (step F8). When the value of AF is "1", two measures consisting of measures (A) and measures (A + 1) are converted into musical score data and stored in RAMA (step F9). On the other hand, when the AF value is “0 (lower display)”, it is composed of measures (A) and measures (A + 1) 2
The measure is converted into musical score data and stored in the RAMB (step F10). When the KF value is "1" in step F7, it is determined whether or not the AF value is "1" (step F11). If the AF value is "1", only one bar of the bar (A) is converted into musical score data and stored in the RAM A (step F12). On the other hand, when the value of AF is “0”, it is 1 in bar (A).
Only the measures are converted into musical score data and stored in RAMB (step F13).

If there is no data in the measure (A) in step F2, it is determined in the flow of FIG. 17 whether the conversion of the specified measure is completed (step F1).
4). If not finished, that is, if the unconverted data still remains in the specified measure, this flow is finished. When the conversion of the designated measure is completed, the value of PF is returned to "0" (step F15). Next, it is determined whether or not the value of KF is "0" (step F16). If this value is "0", then A
It is determined whether the value of F is "0" (step F1).
7). If the AF value is “1”, the variable E is set to “A
The value "+1" is stored (step F18). That is, the measure number of the measure stored in the RAMA and converted into the score data is updated. AF value is "0"
If it is, the value of “A + 1” is stored in the variable F (step F19). That is, the measure number of the measure stored in the RAMB and converted to the score data is updated. After updating the value of the variable E or F, "2" is added to the value of the variable A which is the pointer of the bar number to be specified next and updated (step F).

In step F16, the value of KF is "1".
If it is, it is further determined whether or not the AF value is "0" (step F21). When the AF value is "1", the value "A" is stored in the variable E (step F22). If the value of AF is "0", the variable F
The value of "A" is stored in (step F23). Variable E
Alternatively, after updating the value of F, "1" is added to the value of the variable A, which is the pointer of the bar number to be designated next, and updated (step F24a). After updating the value of A in step F24a, the value of KF is returned to "0" (step F24b). After this, or after updating the value of A in step F20, the value of AF is inverted (step F2
5) Then, the value of GF is returned to "0" to indicate that the conversion into the required musical score data is completed (step F26).
Then, the process returns to the main flow of FIG.

A measure 92 displaying only one score image and having a key signature (from A major to E flat major) is displayed at the beginning of the lower row.

As described above, according to the above embodiment, 2
If there are no key signatures in any of the specified number of measures above the specified number of measures, the score images corresponding to the specified number of measures from the first measure to the last measure are collectively displayed,
When there is a key signature in an arbitrary number of measures, the score images corresponding to the bar from the first measure of the specified number of measures up to the bar immediately before the key number are collectively displayed, and The score images corresponding to the measures from the first bar to the subsequent measures are displayed together. When the reproduction of the music data corresponding to the displayed score image is completed, the score image is changed to the score image corresponding to the music data to be reproduced next. Therefore, the user can sufficiently recognize that another key is transposed in the middle of the song and that key is displayed in the score image. Further, according to the above-described embodiment, the musical score display processing is executed in the time zone in which the musical sound generation processing is not executed in response to the input of the musical sound generation command from the outside. Therefore,
It is possible to prevent the sound processing from being disturbed due to the image processing of the score image.

In the above embodiment, the display unit 5
On the screen, the score images of up to two measures are displayed in the upper and lower stages, but it is of course possible to display a plurality of measures of three measures or more in each stage. In this case, it is much more likely that the user will miss the key signature, so that the effect of the present invention can be remarkably exhibited.
