Description

  The present invention relates to a rhythm practice system and a program for a rhythm practice system, and more particularly to a rhythm practice system and a program for a rhythm practice system that can be easily understood and practiced even by beginners who do not have musical skills and knowledge.

  Patent Document 1 describes a Japanese drum score intended for learning how to beat a Japanese drum. In this Japanese-style drum score, the type of the drum or drum to be used is indicated by the position of the note head on the trigraph, the direction of the note tail, and the diagonal line on the note head. Patent Document 1 discloses, as a conventional technique, dictation characters such as a small drum “do”, a small drum “to”, a rest “u”, an edged “ka”, and a sludge “chi”. There is also a Japanese drum score written with a mark such as a “white circle” mark for a large drum and a “black circle” mark for a small drum.

In recent years, music practice systems using computers have been proposed. In the practice of rhythm striking in a music practice system using a computer, the computer instructs the rhythm striking as the music plays. For example, a rhythm score is displayed on the screen, and a rhythm strike is instructed by shining the note heads of the timing of the strike. Or, display a drum or other percussion instrument picture on the screen, bring the object picture equivalent to the note close to the drum at a speed that matches the tempo, and hit it so that it is positioned in the middle of the drum Instruct the timing.
Japanese Utility Model Publication No. 54-36756

  However, the musical score described in Patent Document 1 is used exclusively for rhythm-playing practice of Japanese drums, and cannot be applied to rhythm-playing practice with other musical instruments. Moreover, it is necessary to prepare a musical score for each musical piece in advance regardless of what kind of notation is used. In addition, it is difficult to understand the timing of rhythm strikes only by the notation of the score. Since the score to be written is premised on reading some Western music, it is difficult not only for beginners, but also because it is a unique notation, there is a problem that it is difficult to use other than Japanese drums.

  Rhythm practice in a computer-based music practice system simply captures the timing of rhythm strike as an image of the position of the object, and it can be applied as a song or practice system. There is a problem that there is little educational effect.

  An object of the present invention is to provide a rhythm practice system and a program for a rhythm practice system that can be easily understood and practiced even by beginners who do not have musical skills and knowledge.

In order to solve the above-mentioned problems, the present invention provides a rhythm practice system for practicing rhythm using a musical score displayed on the screen as a guide, storage means for storing music data for rhythm practice, and music read from the storage means Based on the data, a figure representing the length of notes and rests and a rhythm vocal string in which the lengths of notes and rests are replaced with predetermined strings are automatically generated in real time. A musical score creation means for automatically generating a musical score with a rhythm vocal character string in real time by both a graphic and a rhythm vocal string, and a musical score or rest length automatically generated by the musical score creation means. There is a first feature in that the display means for displaying the graphic representing the rhythm and the rhythm singing character string so as to correspond to each other is provided.

Further, in the present invention, the musical score creation means is a figure representing the length of a note or rest, and the length of a rhythm staff or notes in which notes and rest are arranged on a straight line is represented by an ellipse width. A second feature is that the generated pictorial music is selectively automatically generated in real time.

Further, the present invention provides a melody accompanied by a rhythm vocal character string in place of the musical score of a rhythm musical score accompanied by a rhythm vocal character string or in addition to a musical score of a rhythm musical score accompanied by a rhythm vocal character string. Alternatively, there is a third feature in that a musical score of an accompaniment score is automatically generated in real time, and the display means selectively displays a musical score of a melody or accompaniment score accompanied by a rhythm vocal string .

Further, according to the present invention, when a musical score of a rhythm score accompanied by a rhythm vocal character string is displayed on the display means, the display means further performs note heads on the displayed musical score in accordance with the sounding timing. There is a fourth feature in that a bouncing ball moving toward the head is displayed.
Further, according to the present invention, when a musical score of a melody or accompaniment score accompanied by a rhythm vocal string is displayed on the display means, the display means further performs a musical note on the displayed musical score in accordance with a pronunciation timing. There is a fifth feature in that a bouncing ball moving toward the note head is displayed.

Further, the present invention has a sixth feature in that on the musical score displayed on the display means, the display mode of the sounding part of the musical score accompanied by the rhythm vocal character or the display mode changes to the reproduction position. .

In addition, the present invention further includes an input unit that captures a timing signal that has been rhythmized, and a determination unit that determines the rhythmic performance by comparing the timing signal captured by the input unit with the music data. There is a seventh feature.

  The present invention can be realized not only as a rhythm practice system but also as a rhythm practice system program. If this program is installed in a computer, the computer functions as a rhythm practice system.

The present invention is based on music data, based on music data, a figure representing the length of a note or rest, and a rhythm utterance character string in which the length of a note or rest is replaced with a predetermined character string. automatically generated in real time, than you automatically generate music shapes with rhythm port唱string in real time by both automatically generated graphic and rhythm port唱string rhythm port唱string for each music There is no need to prepare it in advance, and the present invention is not limited to drum rhythms.

  In addition, according to the present invention, since the rhythm vocal character string is displayed together with the musical score, it is possible to easily practice rhythm making even if the musical score cannot be read. Also, by pre-reading the rhythm singing character string, the practitioner can easily store the rhythm as a unit in his / her head, so the learning effect can be steadily improved.

  In addition, it is possible to select picture scores, rhythm scores, and melody and accompaniment scores, so the practitioner first displays the score and practice, and then matches the rhythm score and score. You can practice playing rhythms by displaying the score. Moreover, it is easy to visually understand the length of the sound and the rest from the pictorial score, and then use the rhythm vocal character as a common source to grasp the length of the note and rest, and the rhythm score and the score itself. Can read. Also, picture, rhythm, and score can be selected instantly even in the middle of the song, so you can switch between the unskilled part and the mastered part of the song as appropriate. So that you can learn rhythms smoothly in steps.

  The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a rhythm practice system according to the present invention. The present invention can also be realized as a rhythm practice system program that causes a computer to function as a rhythm practice system.

  The rhythm practice system of this embodiment includes a personal computer main body 11, an input unit 12 such as a keyboard and a mouse, a display unit 13 such as an LCD, and a reproduction unit 14 for reproducing musical sounds. The playback unit 14 may be attached to a personal computer. As the personal computer main body 11, a well-known computer having a storage unit 16 such as a CPU 15, a ROM, a RAM, or a hard disk can be used, but a personal computer 11 having a MIDI interface 17 capable of inputting and outputting MIDI signals is preferable.

  A rhythm practice system program for executing processing according to the present invention is installed in advance in the ROM or hard disk of the storage unit 16 of the personal computer main body 11. The music data for rhythm practice can be stored in the storage unit 16 in advance, and can be acquired from the outside via the MIDI interface 17.

  The overall operation of the present invention will be described. This operation is executed by reading a rhythm practice system program stored in the ROM of the storage unit 16 or the hard disk into the RAM based on a predetermined operation at the input unit 12. Is done.

  First, a menu screen is displayed on the display unit 13. In the menu screen, when the practitioner operates the input unit 12 to select (select) a song to be practiced for rhythm and instruct the start of practice, the bar score information on the bars that can be displayed on the screen of the display unit 13 Music data including measure accompaniment information is read out or acquired from the storage unit 16 or the MIDI interface 17.

  CPU15 produces | generates the information regarding the content which should practice rhythm based on the read music data in real time. The display unit 13 displays the generated information as a rhythm practice guide on the screen. Also, the playback unit 14 outputs performance information such as melody, bass, and rhythm based on the current time from the start of performance (hereinafter simply referred to as the current time) and the read bar accompaniment information, for example, by MIDI output. Reproduce.

  FIG. 2 shows an example of music data for rhythm practice. The music data for rhythm practice is composed of an arrangement for the number of music bars of bar score information and bar accompaniment information. The bar score information is display information for displaying a score and lyrics, and includes an array of symbol information and lyrics information. The measure accompaniment information is performance information mainly for reproducing music, and is composed of an array of musical tone information, tempo information, and effect information. The musical tone information, symbol information, and lyrics information include various information shown in FIG. 2 and are associated with each other by ID.

  While practicing, the practitioner operates the input unit 12 while listening to the music reproduced by the reproducing unit 14 while watching the display on the display unit 13, and practice rhythm. The operation of the input unit 12 in this case is a mouse click, a keyboard press, or the like, and a sound different from the musical sound may be superimposed and output from the playback unit 14 at the timing when the operation is performed.

  The input unit 12, the display unit 13, and the playback unit 14 operate by a timer interrupt or the like. When the reproduction reaches the end of the music, or when the practitioner interrupts the practice on the way, the reproduction of the music is stopped and the practice is ended.

  The personal computer main body 11 is provided with a processing function such as taking in the timing signal rhythmed by the practitioner through the input unit 12 and determining whether or not the rhythm has been correctly input, and displaying the determination result on the display unit 13. You can also. This processing function can be realized by comparing measure accompaniment information, current time, and timing signal.

  The CPU 15 generates, as information to be displayed on the display unit 13, a picture score with a rhythm vocal character string or a rhythm score with a rhythm vocal character string. A rhythm is represented by a picture pattern in a picture score, and a rhythm pattern of notes in a rhythm score. The rhythm vocal character is a character that expresses the length of the corresponding note or rest in an intuitive manner, and is generated in correspondence with the type of the note or rest and the position on the time axis in the measure. Whether to display a picture score or a rhythm score can be selected by the input unit 12, and when the picture score and the rhythm score are switched, a measure corresponding to the picture score and the rhythm score is displayed. The display position on the unit 13 is the same.

  FIG. 3 shows an example of a picture score with a rhythm vocal string. In this example, the bars are represented by rectangles, and the inside is separated by vertical lines so that the beat and time signature can be grasped. By using long circles instead of notes and changing their width according to the length of the notes, the length of the notes can be easily understood visually. Note that the width of the oval does not have to be proportional to the length of the note. Rhythm singing characters should be displayed in each of the long circles from the viewpoint of the appearance of the score display and ease of grasping. In addition, the long circle is not written in the rest portion. This is because it can be intuitively understood that there is a rest by the gap between Nagamaru and Nagamaru. Characters such as “Yes” can be displayed in the gap.

  In addition, the display mode such as the color and density of the rhythm vocal characters can be changed, or the bar rectangle can be used so that the practitioner can easily understand the position of the currently playing musical score and accurately measure the timing of the rhythm. It is better to change the color of the background to the playback position.

  FIG. 4 shows an example of a rhythm score with a rhythm vocal string. In this example, rhythm vocal characters are displayed under individual notes and rests in the rhythm score. Moreover, it is easy to understand visually by changing the space | interval between notes according to the length of a note. Note that the interval between notes does not have to be proportional to the length of the notes. Rhythm singing characters are, for example, “tan” for quarter notes, “ta” for eighth notes, “tar” for half notes, “no” for quarter rests, “yes” for eighth rests , The rest for 2 minutes shall be "U-U". In addition, by generating vocal characters corresponding to the position on the time axis in the measure, for example, when there are four 16th notes within one beat, Rhythm vocal characters such as “K” can be used. As described above, if a rhythm vocal character is written with katakana as a note and hiragana as a rest, it is possible to discriminate between a note and a rest instantaneously.

  In addition, by displaying a bouncing ball that performs a reverse parabola movement between the sounding start timing of the next note and the sounding start timing of the next note, it becomes possible to accurately measure the timing of the rhythm strike. Rather than simply engraving beats and time signatures, it is easy to grasp rhythms by using a bouncing ball that moves toward the note heads according to the timing of sound generation. In addition, it is preferable to change the display mode of the notes and rhythm vocal characters that are being pronounced, such as the color and density thereof, so that the practitioner can easily understand the position of the musical score that is currently being produced.

  FIG. 5 is a main flowchart showing an example of the overall operation of the rhythm practice system according to the present invention. Each process in the main flow is executed by reading a rhythm practice system program stored in the ROM of the storage unit 16 or the hard disk into the RAM.

  First, after various initializations (S51) are performed, the music data of the music is sequentially read from the storage unit 16 in accordance with the music selection (S52) at the input unit 12 and the instruction to start practice. The practice start process (S53) is executed in accordance with the practice start instruction, and the process proceeds to the interrupt process (S54). The interrupt process (S54) includes a display routine, a reproduction routine, and an input routine. When the reproduction reaches the end of the music, or when the practitioner interrupts the practice on the way, the reproduction of the music is stopped and the practice is ended.

  FIG. 6 is a flowchart illustrating an example of the display routine. The flowchart of FIG. 6 displays the rhythm score as shown in FIG. 4 with reference to all musical tone information arrangements and symbol information arrangements in the paragraph including the measure at the current time position. A picture score as shown can be displayed by the same processing. Whether to display a picture score or a rhythm score can be selected by operating the input unit 12.

  This will be specifically described with reference to FIG. First, a reproduction measure is obtained from the current reproduction time (S61), and a start paragraph including the reproduction measure and an end paragraph that fits on the screen of the display unit 13 are obtained (S62). Next, the start point and end point measures are acquired from the start and end paragraphs and the number of measures in the paragraph (S63).

  Next, the musical score for the bars from the start point bar to the end point bar is displayed on the display unit 13. That is, the starting measure bar is indicated by the bar array reference pointer (S64), and the staff and clef symbols are displayed based on all musical tone information and symbol information in the bar, and the symbols are displayed. A rhythm vocal character is displayed for the rest (S65). Subsequently, it is determined whether or not the measure array reference pointer indicates the end measure (S66). If it is determined that the bar array reference pointer does not point to the end bar, the bar array reference pointer is incremented by 1 (S67) and the process returns to S65. Until the bar array reference pointer points to the end bar, the process goes to S65. Repeat the process.

  When it is determined in S66 that the measure array reference pointer indicates the end measure, the musical score for the measure from the start measure to the end measure is displayed on the display unit 13, so that the parent of the musical sound being generated is displayed. Based on the symbol (note), a bouncing ball is displayed for the note of the reproduction measure (S68) to notify the timing of rhythm strike. S68 can also include processing for changing the display mode of the rhythm vocal characters and notes being sounded, the display mode up to the playback position, and the like.

  In the playback routine by interruption, MIDI note information is output to the MIDI sound source by referring to the musical sound information array in the accompaniment information corresponding to the current time and comparing the sounding start time and sounding end time of each sound with the current time. To do. Similarly, the progress degree of the current time is adjusted with reference to the tempo information array in the measure accompaniment information. In the reproduction routine, it is possible to superimpose and output a sound different from the musical sound in accordance with the operation timing of the input unit 12.

  The present invention is not limited to the above embodiment, and various modifications can be made. For example, in the above embodiment, the input unit 12 is operated to practice rhythm striking. However, in the present invention, it is sufficient to display a musical score for rhythm practice on the screen. In addition to the above, it is also possible to use operation means, musical instruments, drum drum kits, etc. that are not coupled to this system. In addition, a keyboard or the like prepared separately can be used as the input unit 12.

  In the above embodiment, selection of a picture score or a rhythm score is possible. However, instead of the rhythm score or in addition to the rhythm score, a score such as a melody or accompaniment as shown in FIG. 7 is automatically generated. Can be switched and displayed. Since the musical score as shown in FIG. 7 also represents the scale in melody and accompaniment, it can be expected that the practitioner can easily shift to the actual musical score.

  In the case of a music piece having a plurality of parts and tracks, a dictation character string may be automatically created based on musical sound data of a specified specific part or a track mainly responsible for the rhythm.
