Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a music composition block creating apparatus for inputting score composition data and creating a score composition based on the input data. The present invention relates to a musical score block making apparatus capable of easily and quickly inputting a tablature and visually confirming the input state.

<Prior Art> Various attempts have heretofore been made to develop a musical score block making apparatus which inputs musical score constituent data and creates a musical score block based on the inputted data. Generally, note data occupies an important position in the score composition data, and regarding how to input and process the note data, European Patent Publication 5339
No. 3 discloses one example. According to the invention disclosed in this publication, the note data is input from the function keyboard together with the pitch data (pitch data) of the pitch 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 the input method as described above, there is a problem in that the note data cannot be smoothly operated because both the pitch data and the sound length data are input by the function keyboard. 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 musical score to be printed is usually a handwritten musical 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 the original, the input speed can be increased. From such an idea, as to a method of inputting pitch data from a piano keyboard type input device, British Patent No. 1337201
No. 6,086,045. 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, since the edited score composition data is printed out by the graphic printer, the system becomes large.

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. Also, since the entered score composition data can be used to create a score on the display screen as the original,
Compared with the conventional music score block making device displayed by a code, it has made remarkable progress.

<Problems to be Solved by the Invention> However, such a score block creating device also has the following problems. That is, it is difficult to create a 6-line staff and a fret number when creating a tablature for a guitar. Here, the tablature of the guitar is a score indicating which position of the strings of the six guitars should be pressed to produce the sound for the person who plays the guitar (especially for beginners). Usually, the score is expressed by 5 lines, so to make it 6 lines, you have to instruct a special input method, or 1 line for 5 lines.
There were inconveniences such as the fact that this operator had to add visually. In addition, even if 6 lines can be created, the operator needs to input all the fret numbers (the numbers indicating the positions where the strings are pressed) corresponding to the notes from the keyboard, which requires a lot of time and effort. there were.

The present invention has been made in order to solve the above-mentioned problems, and it is possible to easily, swiftly and accurately perform the input of 6 lines and the input of the fret number as the tablature for a guitar, and the input thereof. It is an object of the present invention to provide a musical score block making device capable of visually confirming the state in real time.

<Means for Solving the Problems> In order to solve the above-mentioned object, in the present invention, a diatonic key group and a chromatic scale that can press a plurality of notes at the same time and can also press notes with an accidental sign. A first music keyboard means for inputting pitch data corresponding to a key operation, and a plurality of function keys and alphanumeric keys for converting key operation data into tone length data and other data. Memory means for storing the data inputted from the second music keyboard means inputted as the musical score constituent data and the data necessary for the musical score making operation, and a predetermined arithmetic operation is performed on the data stored in the memory means, Moreover, a calculation control means for creating a score based on the calculation result, a display means for displaying the score created by the calculation control means on a screen, and a calculation means for the calculation control means. A musical score data input from the first musical keyboard means and a second musical keyboard, and a display means for displaying the reproduced musical score on the screen and an output means for producing a block copy of the musical score displayed by the display means. Positioning the fret number for the guitar tablature based on the note length data input from the means, automatically input the tablature data, and displaying the input state by the display means each time the data is input. The arithmetic control means is provided with a tablature input function.

<Operation> Therefore, by adopting the means as described above in the present invention, the staff, the time signature, the clef, the clef,
The tone symbol is displayed, and the note data from the first music keyboard means is displayed on the screen in the form of notes. Further, the arithmetic control means automatically determines the position and number of the fret number corresponding to the note and tabs. It is input as music data, and the input state is displayed on the display means in real time each time data is input.

This makes it possible to input tablatures of a large number of complicated notes easily, accurately, and quickly, and to correct input data on the spot when there is an error in input, and to create a score composition properly. Is possible.

<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 is a first musical keyboard means having a diatonic key group and a diatonic key group capable of pressing a plurality of notes at the same time and further pressing notes with accidentals. This is a piano keyboard, and by performing key operations in accordance with the notes of a manuscript, pitch data (pitch data) corresponding thereto is input. Reference numeral 2 is a modified keyboard as a second musical keyboard means having a plurality of function keys and alphanumeric keys. By performing key operation according to the notes of the manuscript, the corresponding tone length data (tone length data) , And other score composition data such as lyrics.

Reference numeral 3 denotes a memory for storing data input from the piano keyboard 1 and the revised sentence keyboard 2, and data required for score creation calculation, and a predetermined calculation is performed on the data stored in this memory, and this calculation is also performed. It is a personal computer including an arithmetic control unit that creates a score based on the result. Here, the arithmetic control unit is based on the pitch data input from the piano keyboard 1 and the pitch length data input from the revised keyboard 2, and an example and a number of the fret (fingering) of the tablature for a guitar. And decide
A function of automatically inputting and displaying the input state on a display unit described later each time data is input, that is, a tablature data input function is provided. Further, the data stored in the memory includes musical score stage data, staff data, note data (pitch data, tone length data), symbol data, and a guitar string scale table.

The string scale table is used to determine the string number and the fret number from the pitch data, and is stored as a table as shown in FIG.

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

Next, based on the flow charts shown in FIGS. 3 and 4, the operation of (tablature) data input in this musical score block making apparatus will be described.

First of all, the operator is the number in one step of the staff, the number of steps,
Input layout data such as size, number of staves, type of time signature, type of clef, number of accidental symbols indicating key signatures, etc., and display the staves, time signature, clef on the screen of the display unit 4. , Display the tone mark (S1). The operator then visually checks this display screen to determine whether the layout is correct (S
2). As a result, if not correct, the layout data is corrected until it becomes correct (S3). Next, after confirming that the layout is correct, the operator inputs the pitch data from the piano keyboard and the pitch data from the revised keyboard 2 to determine the clef and tone marks of the layout data. Based on the above, the screen is displayed in the form of notes on the staff of the screen of the display unit 4 (S4). Then, the operator visually checks this display screen to judge whether or not the note operator is correct (S5). As a result, if it is not correct, the note data is corrected by the mouse 6, the piano keyboard and the modified keyboard 2 until it is correct (S6). Next, after confirming that the note data has become correct, the operator designates the start data of the note data to be tablature with the mouse 6, and the display unit 4
All note data is displayed on the screen in real time in the form of fret number (S7). That is, when the leading note data is designated, the arithmetic control unit in the personal computer 3 calls the displacement of the pitch of the note data when the note shown in FIG. 5 is the origin as the absolute displacement. , This absolute displacement is calculated by adding 1 to the semitone shift. (S7-1) For example, a sound one octave higher is an absolute displacement 12 and a sound two octaves higher is an absolute displacement 24. This absolute displacement is compared with the string scale table shown in FIG. Here, the string scale table shows the sounds that can be expressed by the six strings of the guitar, respectively, by the absolute displacement from the sounds shown in FIG.

Usually, one string can express the sound from the lowest tone of the released string to 2 octaves. By shifting the positions of the frets on the strings one by one, only one semitone is raised.

The first string that produces the highest sound can represent the sound in the range shown in FIG. 6 (a). Similarly, the second string to the sixth house can express sounds in the range shown in FIGS. 6 (b) to 6 (f). Therefore, when expressing a certain sound, it is possible to express with a plurality of strings.
For example, in the case of the sound shown in FIG. 7, the strings from FIG. 6 to the second and sixth strings are possible. Of these, the difference between the absolute displacement of the note data of interest and the absolute displacement of the start of the scale data of the strings stored in the memory of the personal computer 3 is compared (S7-2), and the highest string is selected (S7). -3), that is, the string that can produce the highest tone among the expressible strings is selected. That is, a string close to the open string, which is the easiest for beginners to play, is selected. In the example of FIG. 7, the second string is selected. The scale data of the selected string and the absolute displacement of the target note data are compared to obtain the fret number having the same absolute displacement from the scale data (S7-4).
Next, the arithmetic control unit obtains the center position of the note data of interest, and obtains a position in which half the width of the number of the fret number is shifted to the left from the center position (S7-5). Further, the arithmetic control unit determines the position of the string on the notation by the number of the obtained string (S7-6). Then, the fret number is displayed on the screen of the display unit 4 according to the result of the positioning calculation in the horizontal direction and the vertical direction for the target note (S7-
7). Thereafter, the arithmetic control unit determines whether or not there is the next note (S7-8), determines the string number and the fret number for the next note data by the same operation as described above, and displays it on the screen of the display unit 4. Will be displayed one after another.

Next, when the input of tablature data for one page of the score has been completed as described above, the operator visually checks the input state on the display screen of the display unit 4 to determine whether the input is correct. This is confirmed over the entire page of the score (S-8).

As a result, if there is something wrong with the input, use the mouse 6 to point to that part, input the correct number from the Roman keyboard 2, and display the correct position with the mouse, while looking at the screen. Correct (S9). Also,
When the input is correct, or when it is corrected, the lyrics, chord name, musical symbols, etc. are input (S10) and corrected (S11) to create all the data for one page of the score. Printing out with the printer 5 completes the input of tablature data.

In the above, the operator can arbitrarily specify the size of the characters displayed on the screen of the display unit 4 each time the tablature data is input. Normally, the distance between the lines of the staff in the score (this is 1 0.8) of the unit)
It is about 1.5 times. Similarly, the operator can arbitrarily instruct the character font (font) displayed on the screen of the display unit 4, and the personal computer 3
Stored in memory. In addition, when obtaining the string number on the tablature of the target musical notation, the string that produces the highest note of the multiple strings was selected, but the operator instructs to select the second or third string. can do.

As described above, the musical composition block making apparatus of the present embodiment performs lateral positioning from the center position corresponding to a note, and raises and lowers the string number and fret number based on the scale data of the guitar string. It has a function to automatically determine the direction and the numbers to be displayed. Therefore, the input status of the tablature can be visually checked in real time, so if the specified string number and fret number on the manuscript are different from those displayed, correct them immediately at that point and correct them in a short time. It is possible to obtain the input result, which greatly improves the time loss as compared with the conventional case where the operator manually inputs all the numbers and positions of the fret numbers as the tablature. Further, since the input tablature data is automatically positioned with respect to the note and is displayed on the display unit 4 in real time, the tablature can be input easily, quickly and accurately. The input state can be visually confirmed each time.

<Effects of the Invention> As described above, according to the present invention, the input of 6 lines as a tablature for a guitar and the position and number of the fret number are automatically determined for the notes on the entered staff. It has a tablature input function for inputting and displaying the input state on the display means each time data is input. It is possible to input tablature easily, quickly and accurately and at the same time. It is possible to provide a score block making device capable of visually confirming the state in real time.
