Description

  The present invention relates to a performance assisting device and a program for assisting a performer who wants to play an electronic musical instrument in accordance with the progress of a song.

In recent electronic musical instruments, various mechanisms are conceivable as mechanisms for assisting performance operations by performers. As an example of this, for example, when a player uses an electronic musical instrument having a keyboard composed of a plurality of keys as a performance operator to practice the performance of a song, the player who intends to practice the melody from now on. Conventionally, a performance assisting device and a program for instructing information necessary for keyboard performance, such as a key to be pressed in accordance with the progress of the music and a key pressing timing, by a guide display are known. In a conventional performance assisting device, for example, a guide lamp (also referred to as a key press instruction lamp) built in the key itself is sequentially lit, or a guide lamp arranged for each key is lit in sequence on the upper part of the keyboard. The performance guidance is performed by instructing the key to be pressed corresponding to the melody sound to be played next and the key pressing timing by the guide display. In addition, the guide display of the key to be pressed is not limited to the simple display, but there is also a device that allows the user to practice the performance while playing an accompaniment or the like as a device for making the performance practice more enjoyable. As such a performance assisting device, various devices such as the device described in Patent Document 1 shown below have already been proposed by the present applicant.
Japanese Patent No. 270753

  By the way, depending on the performer, there may be places where it is difficult to perform in the performance song, and for those places that are not good, skip the performance of the part without pressing the key and perform next. There is something that I want to proceed with. However, in the conventionally known performance assisting device, if the performer does not press the key to be played corresponding to the musical piece, the melody is of course until the player presses the key for the key. That is, the progress of the guide display and the progress of the accompaniment are stopped so that the music is not further advanced (so-called waiting mode). In such a case, the progress of the song will always stop temporarily at places where you are not good at playing, especially for players who are relatively difficult to play, such as children and beginners. The performance cannot be performed smoothly throughout the song from the beginning to the end of the song. Then, the performance practice of the electronic musical instrument becomes very boring, and it is difficult for the performer to continue the performance practice. Therefore, for those places where it is difficult to perform with the current technology of the performer, there are places where it is difficult to perform by proceeding with the song even if there is no key press by the performer. Even in some cases, it has been desired that the performer can smoothly perform the entire song from the beginning to the end without greatly interrupting the performance, but there has never been such a thing.

  The present invention has been made in view of the above points. For a portion where the performer wants to skip the performance by operating the performance operator, the performance is automatically performed in place of the manual performance by the performer. Accordingly, the present invention intends to provide a performance assisting device and a program that allow the music to progress.

  A performance assisting device according to the present invention is a performance assisting device used for an electronic musical instrument comprising a performance operator and a musical sound generating means, wherein the performance data includes an acquisition means, and the performance data includes one or more sounds. Section setting means for setting a specific section including: measurement means for measuring an elapsed time from the timing at which the performance operator based on the performance data should be operated; and when the measured elapsed time reaches a predetermined time When the performance data is the set specific section, the music sound generating means is controlled to generate a sound according to the performance data, while when the performance data is not the set specific section. And a control means for controlling the musical sound generating means so as not to generate a musical sound until a performance operator is actually operated.

  According to the present invention, for one or more sounds set in a specific section in the acquired performance data, the elapsed time from the timing at which the performer should operate the performance operator is measured, and the measured elapsed time is measured. If the predetermined time has been reached, the musical sound generating means for generating musical sounds according to the operation of the performance operator or / and according to the predetermined performance data is controlled to generate the musical sounds according to the performance data. On the other hand, with respect to the sound that is not set in the specific section in the acquired performance data, the musical sound generating means is controlled so as not to generate a musical sound until the performance operator is actually operated. In other words, the player can specify a specific section in which the player wants to skip the performance by operating the performance operator, and the performance is advanced by automatically reproducing performance data in place of the manual performance by the player in the specific section. I am doing so. In this way, even if there are places where the performer is not good at playing, the music is automatically played even if the performer does not perform the manual performance at such places. It will be possible to perform smoothly through the entire song from the beginning to the end of the song.

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

  According to the present invention, since the player wants to skip the performance by operating the performance operator, the performance is automatically advanced instead of the manual performance by the performer. Even if there are parts that are not good, it is possible to play smoothly through the entire song from the beginning to the end of the song.

  Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

  FIG. 1 is a hardware configuration block diagram showing the overall configuration of an electronic musical instrument to which a performance assisting device according to the present invention is applied. The electronic musical instrument shown in this embodiment is controlled by a microcomputer including a microprocessor unit (CPU) 1, a read only memory (ROM) 2, and a random access memory (RAM) 3. The CPU 1 controls the operation of the entire electronic musical instrument. For this CPU 1, ROM 2, RAM 3, performance operator interface 4, setting operator 5, panel display unit 6, sound source 7, DSP 8, guide lamp interface 10, and external storage device 11 are respectively provided via the data and address bus 1D. It is connected. Further, the CPU 1 is connected to a timer 1A for measuring the interrupt time and various times in the timer interrupt process (interrupt process). For example, the timer 1A generates a clock pulse, and gives the generated clock pulse to the CPU 1 as a processing timing command or to the CPU 1 as an interrupt command. The CPU 1 executes various processes according to these instructions.

  The ROM 2 stores various programs executed by the CPU 1 and various data. The RAM 3 is used as a working memory that temporarily stores various data generated when the CPU 1 executes a predetermined program, or as a memory that stores a currently executed program and related data. A predetermined address area of the RAM 3 is assigned to each function and used as a register, flag, table, memory, or the like. The performance operator 4A is, for example, a keyboard having a plurality of keys for selecting the pitch of a musical tone, and has a key switch corresponding to each key. The performance operator 4A ( The keyboard etc. can be used for manual (hand-playing) performances by the performer, as well as parameter setting means for setting various performance parameters such as timbres and effects used when playing the electronic musical instrument, and performance guides It can also be used as a performance guide setting means for performing various settings. The performance operator interface 4 generates a detection output by detecting pressing and releasing of each key of the performance operator 4A.

  A setting operator (switch, etc.) 5 is a parameter setting switch for setting various performance parameters used for manual performance or automatic performance, for example, and a performance practice music (specifically performance data corresponding to the music) to be performed as a performance guide. A song selection switch to be selected, a start button and a stop button for instructing start / end of performance practice, and a section in which the performance is automatically advanced after a predetermined time without waiting for the player to operate the performance operation element 4A (this is a specific section) Select a section specifying switch, select the type of performance guide and the performance part (for example, right hand part, left hand part, etc.) to be guided. Performance guide setting settings for various settings related to the performance guide, such as setting the length of the fixed time until Pitch, and the like. The types of performance guides include, for example, a guide display that turns on / off the guide lamp 10A, a guide display that moves the musical notes on the score displayed on the panel display unit 6 while changing colors, and a note name. Any known method may be used, such as a voice guide that informs the user by voice, or a voice accompaniment. Further, a performance guide may be performed by combining a plurality of guides, such as turning on / off the guide lamp 10A and displaying the color of notes on the score. In addition to those described above, the setting operator 5 is a numeric keypad for inputting numeric data, a keyboard for inputting character data, or a panel display unit 6 used for selecting, setting, and controlling pitches, tones, effects, and the like. Various operators such as a mouse used for operating a predetermined pointer displayed on the screen may be included.

  The panel display unit 6 is a display composed of, for example, a liquid crystal display panel (LCD), a CRT, or the like. Is displayed. By referring to these various information displayed on the panel display unit 6, the performer can easily set various performance parameters used for manual performance, various settings related to the performance guide, and the like. For example, as an example of a method for specifying a specific section, the player himself / herself operates one or more sounds (that is, sounds to be automatically played) that the player wants to skip the manual performance after operating the section specifying switch described above. Click the note display corresponding to one or more sounds that you want to be a specific section among the notes on the score displayed on the panel display unit 6, and specify the start position of the specific section on the score and then within the specific section Any number of appropriate methods may be used, such as designating the number of notes to be stored in, or simply designating the start and end positions of a specific section on the score. As for the sound designated in the specific section in this way, it is preferable that an arbitrary mark is attached to the corresponding note on the score displayed on the panel display unit 6 so that it can be easily distinguished from the sound other than the specific section. . As a mark for indicating a specific section on the score, for example, for a note display corresponding to a sound included in the specific section, a certain symbol is displayed near the note, or the display color of the note itself is changed. Good. Multiple such specific sections can be set in a song, and the sound set in a specific section can be canceled at any time by the performer, in which case it is attached to the corresponding note on the score. It goes without saying that it is no longer a landmark. Note that the setting of the specific section is not limited to the manual setting by the performer as described above, and a predetermined interval such as a sound that the performer has failed to play more than the number of times specified in advance by the performer. Sounds that meet the setting conditions may be automatically set to a specific section (see FIG. 4 described later).

  The tone generator 7 can simultaneously generate musical tone signals on a plurality of channels, and is generated in response to the operation of the performance operator 4A by the performer, which is given via the data and address bus 1D, or of performance data. Various performance information generated in response to reproduction is input, and a musical sound signal is generated based on the performance information. A musical sound signal generated from the sound source 7 is generated from a sound system 9 including an amplifier and a speaker via a DSP (Digital Signal Processor) 8. Any conventional configuration may be used as the configuration of the sound source 7, the DSP 8, and the sound system 9. For example, the tone generator 7 may adopt any of various musical tone synthesis methods such as FM, PCM, physical model, formant synthesis, etc., or may be constituted by dedicated hardware or by software processing by the CPU 1. Also good. The guide lamp interface 10 performs performance guidance by controlling lighting / extinguishing (or light quantity, lighting color, etc.) of a guide lamp 10A (for example, an LED arranged for each key in the upper part of the keyboard or inside the key). . That is, in the electronic musical instrument shown in this embodiment, a manual performance by the performer himself / herself is performed by using as a display for guiding and displaying information necessary for the keyboard performance such as a key to be depressed and the key depression timing. The performance guide to assist is performed.

  The external storage device 11 stores various data such as performance data and data related to control such as various control programs executed by the CPU 1. If no control program is stored in the ROM 2 described above, the control program is stored in the external storage device 11 (for example, a hard disk) and read into the RAM 3 to store the control program in the ROM 2. It is possible to cause the CPU 1 to perform the same operation as when In this way, control programs can be easily added and upgraded. The external storage device 11 is not limited to a hard disk (HD), but a flexible disk (FD), a compact disk (CD-ROM / CD-RAM), a magneto-optical disk (MO), a DVD (Digital Versatile Disk), etc. Any storage device may be used as long as the storage device uses various external storage media. Alternatively, it may be a semiconductor memory such as a flash memory.

  Note that the electronic musical instrument described above is not limited to one in which the performance operator 4A, the panel display unit 6 or the sound source 7 is built in one apparatus body, but each is configured separately, and communication means such as a MIDI interface and various networks are provided. Needless to say, the apparatus may be configured to be connected to each other. Furthermore, the performance assist device according to the present invention is not limited to an electronic musical instrument that imitates a keyboard instrument having a keyboard as described above, but for example, a performance operation that imitates each performance method such as a stringed instrument, wind instrument, or percussion instrument that is a natural instrument You may apply to the electronic musical instrument which has a child. In addition, the present invention is not limited to the form of an electronic musical instrument. For example, a personal computer or a karaoke device may be used as long as it has a performance operator and can generate musical sounds electronically by operating the performance operator. The present invention may be applied to any type of device / equipment such as a game device. Furthermore, the present invention is not limited to electronically generating musical sounds, and may be applied to a mechanical piano having a string-striking mechanism combined with a device for reproducing performance data. In particular, it is suitable for an automatic performance piano incorporating a device for reproducing performance data.

  Here, performance data used in the electronic musical instrument shown in FIG. 1 will be described with reference to FIG. FIG. 2 is a conceptual diagram showing an embodiment of the data structure of performance data. As shown in FIG. 2, the performance data is roughly divided into a header, duration data, event data, guide mode on / off data, and end data. The header consists of data such as the tempo of automatic performance, the number of measures of the entire music constituting the performance data, and the default tone color. The event data consists of events such as key-on, key-off, note number, velocity, and the like. Based on this event, the sound to be controlled to turn on / off the guide lamp 10A is determined, or the score is displayed on the panel display unit 6. , You can play automatically. The duration data is data representing a relative time (or the number of clocks) from the previous event data as an example. This duration data is used to determine the timing at which the guide lamp 10A is turned on / off, to display a note or the like at an appropriate position on the score displayed on the panel display unit 6, or to determine the sounding timing at the time of automatic performance. It is used when doing. The guide mode on data and the guide mode off data are between the guide mode on data and the guide mode off data even if there is no operation of the corresponding performance operator 4A by the performer after a certain time has elapsed after the guide lamp 10A is turned on. Musical sound based on certain event data is data defining a specific section in which performance is automatically executed. That is, the guide mode on data is data instructing the start of the specific section, and the guide mode off data is data instructing the end of the specific section. A set of guide mode on data and guide mode off data defining this specific section can be defined at a plurality of locations in the performance data (in this embodiment, only one location is shown). End data is data representing the end of one piece of performance data.

The guide mode on data and the guide mode off data may be stored and managed as data different from the performance data. However, in such a case, duration data indicating the timing at which the guide mode is turned on (that is, the timing for instructing the start of the specific section), and duration data indicating the timing at which the guide mode is turned off (that is, the timing for instructing the end of the specific section). Needless to say, the guide on / off data and the performance data to which the data is applied must be associated with each other.
The duration data may be expressed by the absolute time (or the number of clocks) from the beginning of the song or the beginning of the measure. In other words, the performance data format is the “event + relative time” format in which the event occurrence time is expressed as the time from the previous event, and the note event occurrence time is expressed in absolute time within the song or measure. "Event + absolute time" format, or "pitch (rest) + note length" format that represents performance data in terms of note pitch and note length or rest and rest length, minimum performance resolution Any format may be used, such as a “solid method” format in which a memory area is secured for each time and an event is stored in a memory area corresponding to the time at which a performance event occurs. If there are performance data for multiple parts, the data of multiple parts may be in a time-series format, or the data of multiple parts may be separated for each part. May be in any form. Furthermore, on the memory, time-series performance data may be stored in a continuous area, or performance data that is scattered and stored in a jump area may be separately managed as continuous data. Good. That is, it only needs to be managed as performance data continuous in time series, and it does not matter whether the performance data is continuously stored in the memory.

  Next, “main processing” executed by the electronic musical instrument shown in FIG. 1 will be described with reference to FIG. FIG. 3 is a flowchart showing an example of “main processing”. This process is repeatedly executed from when the electronic musical instrument main body is activated with the main power on operation until it ends with the main power off operation.

  Step S1 initializes the electronic musical instrument. This initialization process includes, for example, a process of clearing performance data read from the ROM 2 or the external storage device 11 as a performance practice song at the time of the previous activation and set in the RAM 3, or a performance set at the time of the previous activation. There are processes such as clearing various settings related to parameters and performance guides. In step S2, it is determined whether or not there is an input from the setting operator 5 when the setting operator 5 is operated by the performer. That is, the setting operator 5 and the performance operator 4A are constantly monitored for the presence or absence of an operation by the performer by an interrupt process (not shown). Here, it is determined whether or not an operation by the performer for the setting operation 5 has been detected. . If it is determined that the setting operator 5 has not been operated and no input has been made (NO in step S2), the process jumps to step S16. On the other hand, when it is determined that the setting operator 5 has been operated and there is an input (YES in step S2), processing corresponding to each operated setting operator 5 is executed.

  First, when the operation of the setting operator 5 relating to the setting of performance practice is an input from the start button instructing the start of performance practice (both step S3 and step S4 are YES), the performance flag is turned on. Set (step S5). For example, “1” is set in the performance flag. If it is an operation of the setting operator 5 for setting the performance practice and it is an input from the stop button that instructs the end of the performance practice (both YES in steps S3 and S6), the performance flag is set to OFF. (Step S7). For example, “0” is set in the performance flag. If it is an operation of the setting operator 5 regarding the setting of performance practice, but it is not an input from either the start button or the stop button (YES in step S3, NO in steps S4 and S6), other instructions The input process is executed (step S8). The other instruction input process includes, for example, a process of changing a performance practice song in accordance with an operation of a song selection switch. Specifically, a song list is displayed on the panel display unit 6, a song selection by the performer is accepted, and performance data corresponding to the accepted song is read from the ROM 2 or the external storage device 11 and set in the RAM 3. To do.

  If the operation of the setting operator 5 relating to the setting of the performance guide (YES in step S9), the selection of the guide type / guide part is accepted according to the operation of each performance guide setting switch (step S10), and the reception is accepted. A guide type / guide part is set (step S11). The performance guide is set to turn on / off the waiting mode, specify the guide type to be applied, such as a guide display that turns on the guide lamp, a guide display that displays the performance position or performance timing on the score, and the like. There is a specification of a performance part (for example, a right-hand part, a left-hand part, etc.), a setting of a certain time until the performance is automatically started in a specific section, and a setting of presence / absence of accompaniment. If it is an operation of the setting operator 5 (section designation switch) relating to designation of a specific section (YES in step S12), designation of the position on the score displayed on the panel display unit 6 is received (step S13), and the designation is made. The set position is set as a specific section (step S14). That is, the section in which the player wants to skip the performance according to the operation of the performance operator 4A by the performer is set according to the manual designation in which the performer clicks an arbitrary position on the score displayed on the panel display unit 6. In response to this, guide mode on data and guide mode off data are added at appropriate positions in the performance data. Of course, it is needless to say that not only a specific section can be set here, but also a specific section that has already been set can be canceled.

  If it is an operation of the setting operator 5 other than the above (NO in step S12), a process according to other input instructions is executed (step S15). For example, when the operation is a parameter setting switch, various performance parameters used for manual performance or automatic performance are set. In addition, although the setting of a specific section showed what a player specified arbitrarily manually, it is not restricted to this, It judges the situation where the player made a mistake at the time of an actual performance as a setting of an electronic musical instrument, and responds to this The specific section may be automatically set (see FIG. 4 described later in detail).

  In step S16, it is determined whether or not a performance guide has been set (see step S9 above). If it is determined that the performance guide has not been set (NO in step S16), the process jumps to step S21. On the other hand, when it is determined that the performance guide has been set (YES in step S16), it is determined whether or not the performance is being practiced (step S17). If the performance flag is on, that is, if the performance flag is on (YES in step S17), the performance data of the performance practice music set in the RAM 3 is pre-read and the sound generation timing is checked (step S18). ). In step S19, it is determined whether or not there is a sound for performing guide display according to the sound generation timing check. If there is a sound for performing guide display, the key guide lamp 10A corresponding to the sound is determined from the sound generation timing. Control is performed so as to light up in advance at a predetermined timing (step S20). That is, in the performance data corresponding to the desired part of the performance practice song selected by the performer, it is determined based on the sound generation timing whether there is a sound to be displayed as a guide at this time (in this case, whether it is a specific section). If there is a sound to be played, a preset type of performance guide is performed at a predetermined timing. Since the predetermined timing for performing the performance guide may be obtained by any known method, description thereof is omitted here. In step S21, performance processing is executed. Since this performance processing will be described later (see FIG. 3 described later), description thereof is omitted here. In step S22, a tone generation process is performed. That is, according to the performance information generated by the performance process, a tone signal is generated by the sound source 7 and a sound generation process is performed.

  Next, the “performance process” (see step S21 in FIG. 3) executed in the “main process” described above will be described. FIG. 4 is a flowchart showing an example of the “performance processing”.

  In step S31, it is determined whether or not there is a performance input corresponding to the operation of the performance operator 4A by the performer. If there is a performance input and the performance input is key-on (both YES in step S31 and step S32), performance information for starting sound generation associated with the operated performance operator 4A is generated. (Step S33). If there is a performance input and the performance input is key-off (step S31 is YES, step S32 is NO, and step S34 is YES), performance information for stopping the sound generation of the corresponding musical sound that has already been generated is generated. (Step S35). If there is a performance input and the performance input is neither key-on nor key-off (step S31 is YES, step S32 and step S34 are both NO), the performance information for starting or stopping the sound generation as described above. In addition to the generation process, other processes according to the performance instruction are executed (step S36). Other performance instructions include, for example, a control instruction (for example, a pitch bend control instruction) for a musical tone that is being generated in response to a pedal or wheel operation.

  In step S37, it is determined whether or not performance is being practiced. That is, it is determined whether the performance flag is on (1) or off (0). If the performance is being practiced, that is, if the performance flag is set to “1” (YES in step S37), it is determined whether or not the waiting mode is set (step S38). If the waiting mode is set (YES in step S38), it is determined whether or not a key pressing operation has been performed on a key whose guide lamp 10A is lit as a guide display (step S39). If a key pressing operation has been performed on a key for which the guide lamp 10A is lit (YES in step S39), the lit guide lamp 10A is turned off (step S40). On the other hand, when the key pressing operation is not performed on the key whose guide lamp 10A is lit (NO in step S39), the time from the sound generation timing of the sound associated with the key to be operated to the present has elapsed. The time is calculated (step S41).

  In step S42, it is determined whether or not the added elapsed time has passed a predetermined time. If it is determined that the predetermined time has not passed (NO in step S42), the process returns to step S31 and the above processes are repeated. If it is determined that the predetermined time has passed (YES in step S42), it is analyzed whether the setting condition of the specific section is met, and the player should play the sound that should have been played with the guide-displayed key as necessary. The specific section is automatically set so as to be included in the target to skip the manual performance by (step S43). That is, the specific section is automatically set here. As an example of the setting condition of the specific section at this time, “the key pressing operation for the sound was not successful over a predetermined number of times specified in advance by the performer”, “the performer included other keys, I didn't press any key at all. " In step S44, the performance data is read and the sound generation timing is checked. Step S45 generates a musical sound signal. In step S44 and step S45, the sound of the parts other than the part that the performer is practicing is controlled according to the performance data except for the specific section, and all the parts including the part that the performer is practicing for the specific section are included. The sound of the part is controlled according to the performance data in the corresponding range. In step S46, it is determined whether or not the performance data is performance data related to the sound set in the specific section. If it is a specific section (YES in step S46), the process returns to step S44, and if it is not a specific section (NO in step S46), the process ends. As a result, only the accompaniment is automatically played as usual except in the specific section, and the accompaniment is automatically played in the specific section, and the melody (performance practice part) is automatically performed instead of the manual performance by the performer. .

  As described above, the performer can smoothly perform the performance through the entire song from the beginning to the end of the song even when there is a weak point. If there is a sound form that is difficult for the performer to perform, it is the purpose of performance practice to overcome the performance for such sound form, but even that sound form (corresponding to a specific section) is not played If you do it, you may be able to play smoothly through all the songs. In such a case, if the player chooses whether to perform a difficult performance practice repeatedly failing until he / she unsuccessfully overcomes the performance, or to play the entire song happily for the time being, the electronic player can freely select it. The performance of will be more fun. Therefore, according to the present invention, as described above, the sound forms that cannot be played well no matter how many times are practiced are automatically played, so that the player can wait for subsequent performance input without playing the sound forms. I am trying to do that.

  A specific example will be described. For example, when practicing the performance of the right-hand part, consider the case where there is a sound that cannot be played due to the fast flow of sound, such as a trill, at the fourth measure. Conventionally, along with the key pressing according to the score with the right hand, the accompaniment performance of the left hand part by the electronic musical instrument is automatically performed according to the set tempo. Here, for example, even if the first three measures can be played at the tempo, there is a case in which the trill sound at the fourth measure is too fast to play at the tempo. In this case, if the performer cannot press the right hand part according to the tempo, the tempo operation is stopped until the key is pressed, and the left hand part is made to wait. Even for these difficult-to-play sound forms, the performance will not proceed unless the specified key is pressed. With conventional electronic musical instruments, the player can play even this sound form (or some of the sounds). I often think that I can go ahead and enjoy the music if I do it. Therefore, as described above, if the performer himself / herself marks the sound form that gives up playing (or some of the sounds), and performs the performance practice with the mark, Sounds with a mark (partial sounds) are not pronounced after the performer presses the key, but they are automatically pronounced after a certain period of time determined by the performer. Even if there is a sound shape that you are not good at, you will be able to play smoothly through the entire song from the beginning to the end of the song.

  In the above-described specific example, the case where an arbitrary sound is skipped when the sound continues such as a trill or the like where the flow of sound is fast and cannot be played is described as an example. For example, if it is difficult to play multiple keys simultaneously, such as chords that require multiple notes to be played at the same time, it is possible to skip playing some of the notes that make up the chords. May be. That is, in the case of a chord, if a mark is given only to a specific sound in the chord, and the performer presses a performance operator corresponding to another sound constituting the chord without the mark, In addition to sounding the key-pressed sound, the sound with the mark that the performance operator is not operated is automatically sounded simultaneously with the player's key press, The performer can easily perform all the sounds constituting the chords even if manual performance is difficult.

Note that a certain period of time until the automatic performance is started may be defined as “0”. In such a case, the performer must continue the performance without interrupting the music continuously in a state where a musical sound that is automatically played and a musical sound that is generated in accordance with the performance operation by the performer are mixed. Therefore, it is possible to easily perform difficult-to-play songs as if the performer himself / herself is playing the entire song, by leaving the electronic musical instrument to the automatic performance for particularly difficult parts. It becomes convenient.
The operation of the performance operator 4A by the performer is shown as an example in the waiting mode in which the performance is not advanced unless the key to be operated instructed by the guide is operated. Alternatively, the any key play mode in which the performance is advanced as if the performance operator 4A was operated by the performer may be used. In addition, although automatic performance in a specific section is performed after a certain time, the present invention is not limited thereto, and automatic performance in a specific section is started when a player performs any operation on the performance operation element 4A or the setting operation element 5, for example. You may make it do.

In addition, although the parts to be automatically played in the specific section are both the melody (playing practice part) and the accompaniment part, at least one of the parts may be automatically played.
Note that the lighting / extinguishing control of the guide lamp 10A in the specific section may be sequentially performed for all the keys of the corresponding sound based on the performance data, or the lighting / extinguishing control of the guide lamp 10A is performed in the specific section. Instead, the key guide lamp 10A corresponding to the first sound to be operated by the performer after the specific section may be lit in advance (or lit at a predetermined timing).
In the embodiment described above, as a condition for determining whether or not the performer is stuck with the performance, it is determined whether or not a key pressing operation has been performed on a key whose guide lamp 10A is lit as a guide display ( However, the present invention is not limited to this. For example, it is also determined by determining whether or not the note number associated with the key operated by the performer matches the note number of the performance data to be played. Good.
