Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of use) The present invention relates to a score block making apparatus for inputting score composition data and creating a score block based on the input data, and more particularly to a score block making apparatus. The present invention relates to a musical composition block making device capable of automatically and easily assigning notes.

(Prior Art) Conventionally, various attempts have been made to develop a musical score block making apparatus that inputs musical score constituent data and creates a musical score block based on the input data. In general,
Note data particularly occupies an important position in the musical score composition data, and regarding how to input and process the note data, European Patent Publication No. 53393 has been published in the past.
An example is disclosed in the issue. According to the invention disclosed in this publication, note data is inputted from the function keyboard together with the pitch data (pitch data) and the pitch length data (pitch data), and the note data is sharpened. When it is necessary to add an accidental symbol such as “#” or a flat “♭”, the accidental symbol is input by further pressing the function key meaning the accidental symbol. However, in such an input method, there is a problem in that the note data cannot be smoothly operated because both the pitch data and the pitch data are input by the function keyboard in common. . That is, for example, the input of chords indicating that three or more tones are played simultaneously must be input separately.

On the other hand, the original of the score to be printed is usually a handwritten score, and if the pitch data can be input from the piano keyboard so that a piano or the like is played while looking at this original, the input can be made into a speed. From such an idea, as to a method of inputting pitch data from a piano keyboard type input device, British Patent No. 1337201
It is disclosed in the publication. According to the invention disclosed in this British patent, it is considered preferable that the note data is input more smoothly than the input using the function keyboard, and that the accidental input is performed by pressing the black key of the piano key. However, in such a system, the edited score composition data is once transferred to the host computer and printed out by the graphic printer, so that the system becomes bulky.

Therefore, in recent years, a device for creating a musical score by a personal computer type has been developed in which the musical composition copy making device is separated from the host computer. This is to easily create a block copy by connecting an output device for creating a block copy to a personal computer. Further, since the inputted musical score composition data can create a musical score on the display screen as a manuscript, it has made remarkable progress as compared with a conventional musical score block making device displayed by a code.

(Problems to be Solved by the Invention) However, such a musical score block making device also has the following problems. That is, the musical score composition data input by the piano keyboard and the function keyboard are displayed on the staff on the screen based on the preset layout. However, in this case, note allocation as to how to arrange the notes on the staff of the score,
Quite high skill is required, and it is very difficult for an amateur to properly perform note assignment. Further, when a note is modified or a layout is changed, it is difficult to deal with this immediately. Furthermore, even if it is assigned by a computer, it is simply assigned by note value, so it is not possible to automatically assign it in the case of a musical score in which accidental symbols, lyrics, etc. are complicatedly intertwined. .

The present invention has been made to solve the above problems, and even in a score in which accidental symbols and lyrics are intricately intertwined, it is easy for an unskilled amateur to assign notes to the staff of the score. It is an object of the present invention to provide a music composition block making apparatus that can be automatically performed and can immediately cope with a note correction and a layout change even after note allocation.

(Means for Solving the Problems) In order to achieve the above-mentioned object, in the present invention, a diatonic key group and a semi-tone key group capable of pressing a plurality of notes at the same time and further pressing a note with an accidental sign. And a scale key group,
A first music keyboard means for inputting pitch data corresponding to key operation, a plurality of function keys and alphanumeric keys, and second for inputting key operation data as tone length data and other musical score constituent data Music keyboard means, memory means for storing data input from the first and second music keyboard means, and data necessary for score creation calculation, and predetermined calculation for the data stored in the memory means. An operation control means for performing a musical score based on the result of the operation, a display means for displaying the musical score created by the arithmetic control means on a screen, and an output means for creating a composition of the musical score displayed by the display means. And assign notes based on at least the distance between notes and the barline space which is the distance between the bar line and the first note of the bar. The required value SP is calculated, and the ratio R (= L / SP) of the value SP to the allocation distance L which is the distance from the first bar line of the musical score to the last bar line of the musical score is calculated. The arithmetic control means is provided with a note assignment function for updating the note interval until R becomes approximately 1 and assigning notes on the staff of the score.

(Operation) Therefore, according to the present invention, by the above means, the operation control means allocates the notes to the staff on the staff based on the data inputted from the music keyboard means and the data necessary for the score making operation. Is done automatically. This makes it easy to assign notes to a staff in a musical score in which accidentals and lyrics are intricately intertwined, and the operator can easily modify the notes and change the layout after assigning the notes. It is possible to properly create the bottom.

(Example) Hereinafter, one example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic diagram showing a configuration example of a musical composition block making apparatus according to the present invention. In FIG. 1, reference numeral 1 denotes a first musical keyboard means having a diatonic key group and a chromatic key group capable of pressing a plurality of notes at the same time and further pressing notes with an accidental sign. It is a piano keyboard, and by operating the keys in accordance with the note data of the manuscript, the corresponding pitch data (pitch data)
Is to be entered. Reference numeral 2 is a function keyboard as a second music keyboard means having a plurality of function keys and alphanumeric keys. By performing key operation in accordance with the note data of the manuscript, corresponding tone length data (sound length data) , And other note structure data such as coded lyrics.

Reference numeral 3 denotes a memory for storing data input from the piano keyboard 1 and the function keyboard 2, and data required for score creation calculation, and a predetermined calculation is performed on the data stored in this memory. It is a personal computer including an arithmetic control unit that creates a musical score based on a result. Here, the arithmetic control unit is provided with a function of automatically determining how to arrange the notes on the staff of the score, that is, an automatic note assignment function described later. Further, the data stored in the memory includes musical score stage data, staff data, note data (pitch data, note length data), symbol data, lyrics data, and the like.

Further, 4 is a display unit for displaying the score created by the arithmetic and control unit of the personal computer on the screen, and 5 is a printer as an output means for printing and making a block copy of the score displayed by the display unit 4. In addition, 6 is a display unit 4.
It is a mouse as an instruction means for instructing the input position of the above data.

Next, the automatic note assignment function of the arithmetic control unit will be described.

First, the following items are given as the conditions for assigning notes.

(1) The distance between notes of the same note value within one stage of the score must be basically the same.

(2) Accidental symbols must not collide with the preceding note.

(3) Musical notes with lyrics must be moved so that the lyrics do not collide.

(4) It must look good.

Next, the method of assigning notes on the score will be described.

In order to express the note value by a numerical value, the note value is determined as shown in FIG. For example, the note value of a dotted quarter note is 16 + 8 = 24. On the other hand, in order to determine the distance between notes within one stage, the minimum note value is basically considered. The minimum note value is the minimum note value among the notes appearing in one stage, and in the case of dotted notes, it is the note value corresponding to the dot. For example, in the case of a dotted quarter note, the note value is equivalent to the eighth note. Further, the distance between notes is not simply proportional to the note value, but is determined as shown in FIG. In the present invention, the relationship between the note value and the inter-note distance can be determined according to the preference of the score writer.

Next, based on the flow chart shown in FIG. 4, the operation of automatic note allocation in the musical score block making apparatus will be described.

First, the case of assigning notes in a simple note arrangement without accidentals and lyrics will be described.

First, the operator sets the initial value of the distance between notes (S1). That is, the distance to which the note assignment is applied is the fifth distance.
As shown in the figure, it is the distance L from the first bar line of the musical score to the last bar line of the musical score, and a note is assigned to this distance L. In this case, as shown in FIG. 6, the note-to-note distance of each note value is set to d1, d2, d3, .... Also, for the note-to-note distance of the notes that hit the end of the bar, assign a small distance to the note-to-note distance of the same note value, and set this note-to-note distance to d
Let 1 ', d2', d3 ', ... Furthermore, the distance between the bar line and the first note of the bar is called the bar line space, and the distances are b1, b2, b3, ....

Next, based on the above-mentioned distance between notes and bar line space, find the value required when assigning notes, and set this value to SP
(S2). That is, in the example of FIG. 6, SP = b1 + b2 + b3 + d1 + d1 + d2 + d2 + d4 + d2 + d2 + d2 + d2 ′ + d2 ′ + d4 ′ Next, the ratio of the value SP to the allocation distance L, which is the distance from the first bar line of the score to the last bar line of the score R
= L / SP is calculated (S3).

Next, this ratio R is almost 1 (within a range in which R does not exceed 1)
It is determined whether or not (S4). As a result, R is 1
If not, the inter-note distance is updated until R becomes almost 1 (S5). That is, the distance between notes (d1, d2, d3, ... and d
1 ', d2', d3 ', ...) are updated.

d1 = d1 x R d1 '= d1' x R d2 = d2 x R d2 '= d2' x R d3 = d3 x R d3 '= d3' x R In this way, update is repeated until R approaches 1. The final note-to-note distance is determined, and the note allocation is completed as shown in FIG. 7 (S6).

Next, a case of assigning notes in a complicated note array including accidentals and lyrics will be described.

The operator sets the initial value of the inter-note distance as in the above (S1).

Next, based on the distance between notes and the minimum fixed value, a value required when assigning notes is obtained, and this value is set as SP (S2).
In this case, the inter-note distances d1, d2, d3, ..., d1 ′, d
In addition to 2 ', d3', ..., bar line spaces b1, b2, b3, ..., the temporary symbol width and inter-lyric distance are also taken into account when assigning notes. That is, as shown in FIG. 8, the accidental width is the distance a from the center of the note to the left end of the accidental, and the inter-lyric distance is 1/2 (s ₁ ) of the width of the lyrics of the immediately preceding note. ,
The total value c (= s) of 1/2 (s ₂ ) of the width of the lyrics of the current note
_It is calculated based on ₁ + s ₂ ). While comparing the above three types of inter-symbol distance, temporary symbol width, and inter-lyric distance,
Make optimal allocation. In the case of the number of notes, the larger value of the distance between notes, the width of accidental symbols, and the distance between lyrics is set as the minimum fixed value of the note, and the minimum fixed value is fixed during the update of the distance between notes as shown in FIG. Determine the new note-to-note distance while securing the value.

That is, in this case, SP = b1 + d1 + a + d1 + d1 + d1 + d1 + d1 + d1 ′ is obtained, and then the ratio SP of the value SP to the allocation distance L = R / L /
Calculate SP (S3). Then, it is determined whether or not this ratio R is approximately 1 (within a range in which R does not exceed 1) (S
Four). As a result, if R is not 1, the inter-note distance is updated until R becomes approximately 1 (S5). That is, the inter-note distances (d1, d2, d3, ... And d1 ', d2', d3 ', ...) Are updated. In this way, the update is repeated until R approaches 1, the final inter-note distance is determined, and the note allocation is completed (S6).

Note that, as shown in FIG. 10, only the distance between notes of a note is specified from the outside, and this is treated as the minimum fixed value, so that the correction after automatic allocation is possible.

Furthermore, even on a musical score that includes clefs, tones, key signatures, bar line types, ornamental notes, etc., by considering the width of each note as the lowest fixed value for each note, It is possible to determine the allocation of notes in a dynamic manner.

As described above, in the musical score block making apparatus of the present embodiment, the value SP required when allocating notes is obtained based on the distance between notes and the minimum fixed value, and from the first bar line of the score row. The ratio R (= L / SP) of the value SP to the allocation distance L which is the distance to the last bar line of the row is calculated, and this ratio R is further calculated.
Since the distance between notes is updated until the value becomes almost 1, the function to perform allocation is provided. Therefore, even in the case of a score in which accidental symbols and lyrics are intricately intertwined, only an expert can be used when creating a conventional score. It is possible for even an inexperienced amateur to easily and automatically perform the note assignment on the staff of the score that could not be done. Also, by only specifying the distance between notes from outside, and treating this as the minimum fixed value,
Even after assigning notes, it is possible to immediately modify notes and change layout.

(Effects of the Invention) As described above, according to the present invention, there is provided a diatonic key group and a chromatic key group capable of simultaneously pressing a plurality of notes and further pressing notes with an accidental sign. And has a first music keyboard means for inputting pitch data corresponding to key operation, a plurality of function keys and alphanumeric keys, and inputs key operation data as tone length data and other musical score constituent data. Second music keyboard means, memory means for storing data input from the first and second music keyboard means, and data necessary for score creation calculation, and predetermined for the data stored in the memory means The calculation control means for performing a calculation and creating a score based on the calculation result, the display means for displaying the score created by the calculation control means on the screen, and the display means. When a note is assigned based on at least the distance between notes and the bar line space which is the distance between the bar line and the first note of the bar, the output means for creating a block copy of the displayed score is provided. The required value SP is calculated, the ratio R (= L / SP) of the value SP to the allocation distance L which is the distance from the first bar line of the musical score to the last bar line of the musical score is calculated, and the ratio R Since the above-mentioned arithmetic control means is provided with a note assignment function for updating the note-to-note distance until notes become approximately 1, and assigning notes on the staff of the score, the score in which accidental symbols, lyrics, etc. are complicatedly entangled Also, even in the case of a staff, even an unskilled amateur can easily and automatically assign notes to the staff of a musical score, and even after assigning notes, it is possible to immediately deal with corrections and layout changes of notes.
