The sound source 16 generates a tone signal representing an accompaniment sound. Sound system 18 includes digital to analog (D / A) conversion circuitry, amplifiers and speakers. The sound system 18 converts tone signals supplied from the sound source 16 into analog sound signals and generates sounds based on the analog sound signals. Thereby, the accompaniment sound is output.

The music score display device 100 further includes a RAM (random access memory) 9, a ROM (read only memory) 10, a CPU (central processing unit) 11, a timer 12, and a storage device 13. The RAM 9, the ROM 10, the CPU 11 and the storage device 13 are connected to the bus 19, and the timer 12 is connected to the CPU 11. An external device such as the external storage device 15 may be connected to the bus 19 via the communication I / F (interface) 14. The RAM 9, the ROM 10, the CPU 11 and the timer 12 constitute a computer 200.

The RAM 9 is, for example, a volatile memory, is used as a work area of the CPU 11, and temporarily stores various data. The ROM 10 is, for example, a non-volatile memory, and stores computer programs such as a control program and a score display program. The CPU 11 executes a score display program stored in the ROM 10 on the RAM 9 to perform a score display process described later. The timer 12 provides time information such as the current time to the CPU 11.

The storage device 13 includes a storage medium such as a hard disk, an optical disk, a magnetic disk, or a memory card, and stores one or more performance music data corresponding to one or more performance music. The music data includes musical score data and accompaniment data. The score data represents the score of the playing part, and is, for example, logical score data. The logical score data is represented, for example, in MusicXML (Extensible Markup Language) format. The music score data may be document data represented in PDF (Portable Document Format) format or the like, or may be image data. The accompaniment data is data representing the sound of the accompaniment part (accompaniment sound), and may be audio data or MIDI (Musical Instrument Digital Interface) data. In this example, the music piece data includes performance data representing a series of notes of the performance part. The performance data is, for example, MIDI data.

Similar to the storage device 13, the external storage device 15 includes a storage medium such as a hard disk, an optical disk, a magnetic disk, or a memory card, and may store at least one of musical piece data and a musical score display program.

The musical score display program according to the present embodiment may be provided in the form of being stored in a computer readable recording medium, and may be installed in the ROM 10 or the storage device 13. Further, when the communication I / F 14 is connected to the communication network, a score display program distributed from a server connected to the communication network may be installed in the ROM 10 or the storage device 13. Similarly, music piece data may be obtained from a storage medium or may be obtained from a server connected to a communication network.

[2] Functional Configuration of Score Display Device FIG. 2 is a block diagram showing a functional configuration of the score display device 100. As shown in FIG. As shown in FIG. 2, the score display device 100 includes a display control unit 51, a progress information acquisition unit 52, a position acquisition unit 53, a position designation unit 54, a bar notification unit 56, a beat notification unit 58, a music reproduction unit 60, and reproduction. A start position designation unit 61 is included. The functions of the display control unit 51, the progress information acquisition unit 52, the position acquisition unit 53, the position specification unit 54, the bar notification unit 56, the beat notification unit 58, the music reproduction unit 60 and the reproduction start position specification unit 61 are the same as the CPU 11 of FIG. Is realized by executing a score display program.

The display control unit 51 acquires musical score data from the musical composition data stored in the storage device 13 and controls the display unit 6 based on the musical score data. As a result, the score of the performance part of the designated music piece is displayed on the screen of the display unit 6. In this example, the displayed score includes at least one long rest. A long rest represents a plurality of consecutive full rests.

The progress information acquisition unit 52 acquires, based on the time information from the timer 12, progress information indicating the progress of the musical composition. The progression of the musical composition includes the progression of the reproduction of the accompaniment sound by the song reproduction unit 60 described later, the progression of the performance by the user, the progression of the command of the conductor, and the like. For example, based on the time information from the timer 12, the progress information acquisition unit 52 counts beats at a preset tempo, and acquires the count value as progress information.

The position acquisition unit 53 acquires a reference position in the musical composition. In this example, the position acquisition unit 53 specifies the current position of the music piece in progress based on the acquired progress information and the performance data stored in the storage device 13 and acquires the specified current position as a reference position. Do. The current position includes the current playing position and the current playing position of the accompaniment sound. The position designation unit 54 designates a reference position on the score displayed by the display unit 6.

The measure notification unit 56 refers to a rest measure including the reference position when the reference position is in any of a plurality of measures corresponding to one long rest (hereinafter referred to as a plurality of rest measures). The measure identification information for specifying as a measure is notified. The user does not play at the plurality of rest bars corresponding to the long rest. The measure notification unit 56 displays measure specification information on the screen of the display unit 6 by, for example, controlling the display unit 6.

The beat notification unit 58 reports the beat corresponding to the reference position in the reference measure. For example, the beat notification unit 58 controls the display unit 6 to display beat identification information for specifying a beat corresponding to the reference position on the screen of the display unit 6.

The music reproduction unit 60 controls reproduction of musical performance music based on musical performance music data stored in the storage device 13. Specifically, the music reproduction unit 60 acquires accompaniment data from the designated musical composition data, and controls the sound output unit 8 so that the accompaniment sound is reproduced based on the accompaniment data. Thereby, the sound output unit 8 outputs the accompaniment sound of the designated musical composition. For example, the operation unit 4 of FIG. 1 includes a start button and an end button. When the user operates the start button, output of the accompaniment sound is started, and when the user operates the stop button, the output of the accompaniment sound is stopped.

The reproduction start position designation unit 61 acquires the reproduction start position of the musical composition. For example, when the user operates the operation unit 4 to designate any position of the musical composition, the designated position is acquired as the reproduction start position. If no measure is specified by the user, the first measure of the musical composition is obtained as the reproduction start position. The reproduction start position designation unit 61 may obtain any one of a plurality of rest bars corresponding to the long rest as the reproduction start position. The music reproduction unit 60 starts reproduction of the musical performance (reproduction of the accompaniment sound) from the reproduction start position acquired by the reproduction start position designation unit 61.

[3] Display Example FIG. 3 and FIG. 4 are diagrams showing display examples of the musical score of the playing part by the display unit 6. 3 and 4 show a part of the score of the playing part. The user can display a desired portion of the score by scrolling the score on the screen of the display unit 6 or changing the displayed page.

In the example of FIGS. 3 and 4, seven long rests T1, T2, T3, T4, T5, T6 and T7 are arranged in the score. Each of the long rests T1 to T7 has a number representing the number of corresponding rest bars. The numbers of rest bars corresponding to the long rests T1 to T7 are "4", "16", "18", "18", "18", "18" and "18", respectively.

The position designation unit 54 in FIG. 2 designates a reference position on the displayed score. For example, the position designation unit 54 makes the display mode of the background of the bar including the reference position different from the display mode of the background of the other part. The display mode of the background includes, for example, the color of the background, the brightness of the background, and the presence or absence of blinking of the background.

In the example of FIG. 3, the reference position is included in the first bar in the sixth row. In this case, the color of a rectangular area (hereinafter referred to as a background area) corresponding to the background of the first bar of the sixth row changes so as to be different from the color of the background of the other part. Thereby, the user can easily recognize which measure the reference position is in.

When the reference position is in any of a plurality of rest bars corresponding to the long rest, the bar including the reference position does not appear alone on the score. Therefore, a measure including a reference position can not be specified on the score. Therefore, in the present embodiment, when the reference position is in any rest bar, the bar notification unit 56 in FIG. 2 notifies the bar specifying information for specifying the rest bar including the reference position as the reference bar. Do.

In the example of FIG. 4, the reference position is at any rest bar corresponding to the long rest T2. In this case, the color of the background area R2 of the long rest T2 changes so as to be different from the color of the background of the other part. Further, measure specifying information is displayed in a specific display area corresponding to the long rest T2. In the present example, an elliptical display window WD is displayed in the background area R2. In the display window WD, a bar specification value BS representing the position of the reference bar among the plurality of rest bars is displayed as the bar specification information.

When the “N ₁ ” measure (N ₁ is a positive integer) among the plurality of rest measures is a reference measure, the measure identification value BS is “N ₁ ”. In the example of FIG. 4, “5” is displayed as the measure identification value BS. Therefore, the fifth bar of the sixteen rest bars corresponding to the long rest T2 is the reference bar.

The reference position moves in accordance with the progress of the music, and the measure identification value BS gradually increases. When the reference position reaches the final bar (hereinafter referred to as the final rest bar) of the plurality of rest bars, the bar identification value BS becomes equal to the numerical value given to the long rest. This allows the user to easily recognize the start point of the next bar of the long rest.

The reproduction start position acquisition unit 61 in FIG. 2 may acquire a position designated by the user on the score displayed by the display unit 6 as the reproduction start position. For example, when a mouse is used as the operation unit 4 of FIG. 1 and the user moves the cursor to any measure on the screen of the display unit 6 and clicks the mouse, the start position of the measure is acquired as the reproduction start position. Ru. Also, when the user moves the cursor to a long rest or its background area and clicks the mouse, an input window for specifying a desired rest measure is displayed. When the user inputs the measure identification value BS into the input window, the start position of the rest measure specified by the measure identification value BS is acquired as the reproduction start position. Also, as in the example of FIG. 4, when the measure identification value BS is displayed in the display window WD, when the user moves the cursor to the display window WD and clicks the mouse, the measure in the display window WD It becomes possible to change the specific value BS. When the bar specification value BS in the display window WD is changed, the start position of the rest bar specified by the changed bar specification value BS is acquired as the reproduction start position. Note that the user may be able to specify an arbitrary position in the rest bar corresponding to the long rest. When a touch panel display panel is used as the operation unit 4 and the display unit 6, the same operation can be realized by performing a tap operation instead of the click operation. In this way, the user can easily designate any rest measure corresponding to the long rest as the reproduction start position on the displayed score. Therefore, it is possible to play the music from any rest measure corresponding to the long rest.

In the example of FIG. 4, the display window WD is displayed below the corresponding portion of the score, but the display position of the display window WD may be changed as appropriate. For example, the display window WD may be displayed above the corresponding portion of the score, or the display window WD may be displayed so as to overlap with the long rest. Further, instead of displaying the measure identification value BS in the display window WD, the numeral attached to the long rest may be temporarily replaced with the measure identification value BS.

In addition, as the measure identification value BS, a numerical value representing the positional relationship between the final rest measure and the reference position may be displayed. For example, the number of rest bars corresponding to one long rest is “N ₂ ” (N ₂ is a positive integer), and the “N ₁ ” bar of “N ₂ ” rest bars is “N ₂ ”. When “参照” is a reference measure, “N ₂ −N ₁ ” may be displayed as the measure identification value BS. In this case, the measure specific value BS gradually decreases with the progress of the music, and the measure specific value BS becomes "0" when the reference position reaches the final rest measure. Also, the bar identification value BS may be defined such that the bar identification value BS when the reference position reaches the final rest bar becomes "1".

In addition, as the measure identification value BS, a numerical value representing the position of the reference measure in the entire musical composition may be displayed. For example, when the “N ₄ ” th (N ₄ is a positive integer) measure from the beginning of all measures of the musical composition is the reference measure, “N ₄ ” may be displayed as the measure identification value BS. Similar numerical values may be displayed for bars other than long rests. For example, when the reference position is in a bar other than the long rest, the display mode of the background area of the bar changes as in the example of FIG. 3, and the bar position is set at a predetermined position (for example, upper left) of the background area. A numerical value representing may be displayed. Alternatively, when the reference position is in any rest bar corresponding to the long rest, the display mode of the long rest background area changes as shown in the example of FIG. In addition to the value BS, a numerical value representing a bar position may be displayed. In this case, the measure identification value BS is preferably a numerical value representing the position of the reference measure in the plurality of rest measures or the positional relationship between the final rest measure and the reference position.

The measure notification unit 56 of FIG. 2 may notify measure specification information in a mode determined based on the positional relationship between the reference position and the final rest measure. For example, the display mode of the background of the bar specifying information in the display area (the background area or the display window) may change based on the positional relationship between the reference position and the final rest bar. FIG. 5 and FIG. 6 are diagrams for describing changes in the display mode of the background of measure identification information. FIGS. 5 and 6 show an example in which the reference position is in the 14th to 16th bars of the “16” rest bars corresponding to the long rest T2. In FIGS. 5 and 6, the difference in color is represented by the difference in dot pattern.

In the example of FIG. 5, when the reference position reaches the final rest measure, the color of the background area R2 of the long rest T2 changes. In the example of FIG. 6, when the reference position reaches the final rest measure, the color of the display window WD changes. As described above, the display position of the background of the bar identification information is different between the case where the reference position is in the final rest bar and the case where the reference position is in another rest bar, so that the user does not It can be easily recognized that it is in the mark. Therefore, the user can easily recognize the start point of the next measure of the long rest. In particular, when the user starts playing after a long time, such as the measure following the long rest T5 in the example of FIG. 4, the user can easily and appropriately grasp the preparation timing of the performance. . Note that instead of changing the background color of the measure identifying information, the brightness of the background of the measure identifying information may change, or the background of the measure identifying information may blink. Further, instead of changing the display mode of the background of the bar specifying information, the display mode of the bar specifying information (in this example, the bar specifying value BS) may change.

The display mode may not be changed only when the reference position is in the final rest bar, and the display mode may gradually change as the reference position approaches the final rest bar. For example, the color of the background of the bar identification information may gradually change as the reference position approaches the final rest bar. Specifically, the color of the background area is blue when the reference position is at the first rest bar of the plurality of rest bars, and the color of the background area is blue as the reference position approaches the final rest bar The color gradually approaches red, and when the reference position reaches the final rest measure, the color of the background area turns red. In this case, the user can easily recognize that the reference position is approaching the final rest measure.

As the measure identification information, a specific mark or figure or the like may be displayed instead of or in addition to the measure identification value BS. 7 and 8 are diagrams for explaining another display example of measure specification information. In the example of FIG. 7, when the reference position reaches the final rest measure, the mark MK1 of a specific shape (in the present example, a star shape) is displayed as measure specifying information in the background area R2. This allows the user to easily recognize that the reference position is in the final rest measure.

In the example of FIG. 8, a graphic FK of a specific shape (in this example, a circle) is displayed above the background region R2 as the measure identification information. The display position of the graphic FK corresponds to the reference position. In the example of FIG. 8, when the reference position is at the first rest bar, the graphic FK is displayed at the upper position of the left end of the background area R2. When the reference position moves with the progress of the music, the graphic FK gradually moves to the right. When the reference position is in the final rest bar, the graphic FK is displayed at the upper position of the right end of the background area R2. In this case, the user can easily recognize the reference position in the plurality of rest bars based on the position of the graphic FK. It should be noted that, instead of the circular figure FK, a straight or rod-like figure extending up and down may be displayed so as to cross the corresponding part of the score. Also, in the bars other than the long rest, similar straight or rod-like figures may be displayed so as to designate the reference position of the score.

Further, in the example of FIG. 8, the number of figures FK may be changed instead of the figures FK moving. For example, when there is a reference position in the “N ₁ ” bar of the plurality of rest bars, “N ₁ ” figures FK may be displayed. In this case, the number of figures FK gradually increases as the music piece progresses. Alternatively, when the number of rest bars corresponding to the long rest is "N ₂ ", "N ₂ -N ₁ " pieces of graphics FK may be displayed. In this case, the number of figures FK gradually decreases with the progress of the music piece. In this case, the user can easily recognize the reference position in the plurality of rest measures based on the number of figures FK.

FIG. 9 is a diagram for explaining yet another display example of measure specification information. In FIG. 9, a virtual circle VL1 is shown so as to surround the bar identification value BS. In the example of FIG. 9, the graphic FM1 is displayed as the measure identification information. The figure FM1 extends stepwise in the clockwise direction along the virtual circle VL1 from the starting point position SP1 set on the virtual circle VL1 as the musical tune progresses.

Specifically, the length of the virtual circle VL1 corresponding to one bar is divided by dividing the circumferential length of the virtual circle VL1 by the number of rest bars corresponding to the long rest (hereinafter, unit bar The length is called). When the reference position is in the “N ₁ ” measure among the plurality of rest measures, the circumferential length of the figure FM1 is set to unit measure length × N ₁ .

In the example of FIG. 9, the number of rest bars is "16". Therefore, the unit bar length is one sixteenth of the circumferential length of the virtual circle VL1. When the reference position is in the first bar of the plurality of rest bars, a graphic FM1 extending clockwise by unit bar length from the start position SP1 along the virtual circle VL1 is displayed. When the reference position is the second bar among the plurality of rest bars, a graphic FM1 extending clockwise from the start position SP1 along the virtual circle VL1 by a length twice the unit bar length is displayed. Thereafter, similarly, the figure FM1 gradually extends in the clockwise direction along the virtual circle VL1 as the musical tune progresses. When the reference position reaches the final rest bar, an annular figure FM1 is displayed along the entire virtual circle VL1. In this case, the user can easily recognize the reference position in the plurality of rest bars based on the circumferential length of the graphic FM1. It should be noted that the length of the figure FM1 may be changed continuously as the performance tune progresses, instead of changing the length of the figure FM1 stepwise. Also, the figure FM1 may extend counterclockwise instead of clockwise.

FIG. 10 is a diagram for describing still another display example of measure specification information. In the example of FIG. 10, the graphic FM2 is displayed as the measure identification information. The figure FM2 moves stepwise in the clockwise direction from the start position SP1 on the virtual circle VL1 as the musical composition progresses. Specifically, when the reference position is in the "N ₁ " bar among the plurality of rest bars, the position of the figure FM2 is unit bar length x N ₁ clockwise on the virtual circle VL1 from the start position SP1 It is set at a position far away.

In the example of FIG. 10, as in the example of FIG. 9, the unit measure length is one sixteenth of the circumferential length of the virtual circle VL1. When the reference position is in the first bar of the plurality of rest bars, the graphic FM2 is displayed on the virtual circle VL1 at a position separated by the unit bar length clockwise from the start position SP1. When the reference position is in the second bar among the plurality of rest bars, the graphic FM2 is displayed on the virtual circle VL1 at a position separated by a length twice the unit bar length clockwise from the start position SP1 Ru. After that, similarly, the figure FM2 moves stepwise clockwise on the virtual circle VL1 as the musical tune progresses. When the reference position reaches the final rest measure, the figure FM2 reaches the start position SP1. In this case, the user can easily recognize the reference position in the plurality of rest bars based on the position of the graphic FM2. The position of the figure FM2 may be changed continuously as the performance tune progresses, instead of the position of the figure FM2 changing stepwise. Also, the figure FM2 may move counterclockwise instead of clockwise.

In addition to the measure identification information, beat identification information indicating a beat corresponding to the reference position may be displayed by the beat notification unit 58 of FIG. FIG. 11 is a diagram showing a display example of beat identification information. In FIG. 11, a virtual circle VL2 is shown so as to surround the bar identification value BS. In the example of FIG. 11, a graphic FB1 is displayed as beat identification information. Similar to the figure FM1 of FIG. 9, the FB1 extends stepwise stepwise clockwise along the virtual circle VL2 from the start position SP2 set on the virtual circle VL2.

Specifically, the circumferential length of the virtual circle VL2 is divided by the number of beats of the reference measure, whereby the circumferential length of the figure FB1 corresponding to one beat (hereinafter referred to as unit beat length). Is required. When the reference position is in the “N ₃ ” beat (N ₃ is a positive integer) in the reference measure, the circumferential length of the figure FB ₁ is set to unit beat length × N ₃ .

In the example of FIG. 11, the beat of the reference measure is four quarters. Therefore, the unit beat length is one fourth of the length of the circumference of the virtual circle VL2. When the reference position is in the first beat of the reference bar, a graphic FB1 extending clockwise by a unit bar length from the start position SP2 along the virtual circle VL2 is displayed. When the reference position is at the second beat of the bar, a graphic FB1 extending clockwise from the start position SP2 along the virtual circle VL2 by a length twice the unit bar length is displayed. After that, similarly, the figure FB1 gradually extends clockwise along the virtual circle VL2 as the musical composition progresses. The user can easily recognize the reference position in the reference measure by looking at the figure FB1. In addition, the user can intuitively recognize the tempo of the musical composition from the change speed of the length of the graphic FB1. It should be noted that the length of the figure FB1 may be changed continuously as the performance tune progresses, instead of changing the length of the figure FB1 stepwise. Also, the figure FB1 may extend counterclockwise instead of clockwise.

FIG. 12 is a diagram showing another display example of beat identification information. In the example of FIG. 12, a graphic FB2 is displayed as beat identification information. Similar to the figure FM2 of FIG. 10, the figure FB2 stepwise moves clockwise on the virtual circle VL2 from the start position SP2. Specifically, when the reference position is at the “N ₃ ” beat in the reference measure, the position of the figure FB2 is set at a position on the virtual circle VL2 away from the start position SP2 by unit beat length × N ₃ Ru.

In the example of FIG. 12, as in the example of FIG. 11, the unit beat length is one fourth of the circumferential length of the imaginary circle VL2. When the reference position is in the first beat of the reference bar, the graphic FB2 is displayed on the virtual circle VL2 at a position away from the start position SP2 clockwise by the unit bar length. When the reference position is in the second beat of the bar, the graphic FB2 is displayed on the virtual circle VL2 at a position separated from the start position SP2 clockwise by twice the unit bar length. Thereafter, similarly, the figure FB2 moves stepwise clockwise on the virtual circle VL2 as the musical composition progresses. The user can easily recognize the reference position in the reference measure by looking at the position of the graphic FB2. In addition, the user can intuitively recognize the tempo of the musical composition from the change speed of the position of the graphic FB2. The position of the figure FB2 may not be changed stepwise but the figure FB2 may move continuously on the virtual circle VL2 as the musical composition progresses. Also, the figure FB2 may move counterclockwise instead of clockwise.

The display as shown in FIGS. 8 to 12 may be used to designate the reproduction start position in a plurality of rest bars corresponding to the long rest. For example, the user operates the mouse or touch panel display to move figure FK of FIG. 8 or figure FM2 of FIG. 10, or adjust the length of figure FM1 of FIG. The rest measure of may be designated as the reproduction start position. Alternatively, the user can designate an arbitrary position (beat) in any rest measure as the reproduction start position by moving the graphic FB1 of FIG. 11 or adjusting the length of the graphic FM2 of FIG. It may be As a result, the user can arbitrarily designate the reproduction start position in the plurality of rest bars corresponding to the long rest by a more intuitive operation.

[4] Score Display Process Next, a score display process by the score display method according to the present embodiment will be described. FIG. 13 is a flowchart showing an example of the score display process by each functional unit in FIG. The music score display process of FIG. 13 is performed by the CPU 11 of FIG. 1 executing a music score display program stored in the ROM 10 or the storage device 13.

First, when the user operates the operation unit 4 of FIG. 1 to specify musical piece data, the display control unit 51 receives specification of musical piece data (step S1). Next, the display control unit 51 controls the display unit 6 based on the musical score data included in the specified musical composition data to display the musical score of the musical performance part on the screen of the display unit 6 (step S2). .

Next, the progress information acquisition unit 52 determines whether the start of the musical composition has been instructed. For example, when the user operates the start button, the start of the musical composition is instructed. The progress information acquisition unit 52 repeats step S3 until the start of the musical composition is instructed. When the start of the musical composition is instructed, the musical composition reproducing unit 60 controls the sound output unit 8 based on the accompaniment data included in the designated musical composition data to output the accompaniment sound from the sound output unit 8. Is started (step S4). Further, the progress information acquisition unit 52 starts acquisition of the progress information based on the time information from the timer 12 of FIG. 1 (step S5).

Next, the position acquisition unit 53 acquires a reference position (current position) in the musical composition based on the acquired progression information (step S6). Next, the position acquisition unit 53 determines whether the acquired reference position is in any rest bar corresponding to the long rest (step S7). If the reference position is not in any rest bar corresponding to the long rest, the bar containing the reference position is represented alone on the displayed score. In that case, the position designation unit 54 designates a measure including the reference position on the displayed score (step S8), and the process proceeds to step S13 described later.

When the acquired reference position is in any rest bar corresponding to the long rest, the position specification unit 54 specifies the long rest corresponding to the rest bar including the reference position on the displayed score. (Step S9). Next, the position acquisition unit 53 acquires a rest measure including the reference position as a reference measure (step S10). Next, the measure notification unit 56 notifies measure specification information for specifying the acquired reference measure (step S11). For example, the measure notification unit 56 controls the display unit 6 to display measure identification information on the screen of the display unit 6. Next, the beat notification unit 58 notifies the beat corresponding to the reference position in the acquired reference measure (step S12). For example, the beat notification unit 58 controls the display unit 6 to display beat identification information on the screen of the display unit 6.

Next, the progress information acquisition unit 52 determines whether or not stop of the musical composition has been instructed (step S13). For example, when the user operates the stop button, stop of the musical composition is instructed. Alternatively, it may be determined that the stop of the musical composition is instructed when the current position in the musical composition reaches the end position of the musical composition. When the stop of the performance is not instructed, the position acquisition unit 53 returns to step S6. When an instruction to stop the musical composition is instructed, the musical composition reproducing unit 60 performs a mute process so as to stop the output of the accompaniment sound (step S14). Thus, the score display process is completed.

[5] Effects of the Embodiment In the score display device 100 according to the present embodiment, when the reference position is in any of a plurality of rest bars corresponding to the long rest, the reference bar including the reference position is specified. Bar specification information to be played is notified. Thereby, the user can grasp the reference measure even when the reference position is in any rest measure. Therefore, even if a long rest is used, the user can easily recognize the reference position in the song.

[6] Other Embodiments In the above embodiment, the measure identification information is displayed on the score, but the measure identification information may be displayed at a position different from the score. For example, a score display area and an auxiliary display area may be separately provided on the screen of the display unit 6, a score may be displayed in the score display area, and measure specification information may be displayed in the auxiliary display area. In that case, the display form of the background of the bar identification information in the auxiliary display area may change based on the position of the reference bar in the plurality of rest bars or the positional relationship between the final rest bar and the reference position.

In the above embodiment, the measure identification information is displayed when the reference position is in any rest measure corresponding to the long rest, but when the reference position is in the measure corresponding to all rests, the measure identification information May be displayed. For example, when the reference position is in the measure corresponding to all rests, “1” may be displayed as the measure identification value BS.

In the above embodiment, the performer (user) performs while the accompaniment sound is output from the musical score display device 100, but the usage mode of the musical score display device 100 is not limited to this. For example, when a plurality of performers perform a concert, each performer may perform while watching the score displayed by the score display device 100. In this case, the musical score display device 100 does not output the accompaniment sound. Further, the score display apparatus 100 may be used when the performer sings while watching the score as well as when the performer plays.

In the above embodiment, the current position in the musical composition is acquired as the reference position, but another position may be acquired as the reference position. For example, when a plurality of performers perform a concert as described above, a conductor, a performer, or another person designates an arbitrary position in the music by operating the score display device 100 or an external device. Do. In this case, position information representing the designated position is transmitted to each musical score display device 100. Each score display device 100 may acquire the position indicated by the received position information as a reference position.

Although bar specification information is displayed on the screen of the display unit 6 in the above embodiment, the bar specification information may be notified in other manners. For example, measure specification information may be notified by sound or light, or measure specification information may be notified by movement of a robot. As a specific example, when the reference position is in any of the rest bars, a click sound is output from the sound output unit 8, and the position of the reference bar among the plurality of rest bars or the final rest bar and the reference position On the basis of the positional relationship of (1), the output mode (such as pitch or tone generation period) of the click sound may change. Similarly, instead of being displayed on the screen of the display unit 6, the beat identification information may be notified by sound, light or the movement of a robot.

In the above embodiment, each functional unit in FIG. 2 is realized by hardware such as the CPU 11 and software such as an evaluation program, but these functional units may be realized by hardware such as an electronic circuit.

The music score display device 100 may be applied to an electronic musical instrument such as an electronic keyboard instrument, and may be applied to another electronic device such as a personal computer, a smartphone or a tablet terminal.
