(Refer to [Point of conversion] in Figure 2)
In addition to the above-mentioned musical tone information, bibliographical information such as the type of musical instrument, the title of the song, the key, and the time signature is input. The input music information (bibliographic information and musical tone information) is stored in a storage medium, and based on the music information, the computer 5 converts the musical score into a performance operation support tool, prints the processing result by the printer 12, and performs musical instrument performance operation Get support 2 The details of the process are described below.

The musical instrument performance operation support tool 2 is created in the step shown in FIG. 3 in the musical instrument performance operation support tool creation apparatus 1.
(Music information input process)
Music information 20 is input to the computer 5 of the musical instrument performance operation support tool creation apparatus 1 via input means such as the keyboard 10 shown in FIGS. (Step 1)
As shown in FIG. 4 and FIG. 5, the music information 20 includes the type of musical instrument, the title of the song, tone, beat, tempo, etc. as the bibliographic information 21 and the pitch, note value, presence or absence of multiple tones, and rest as the tone information 22. Contains note information such as notes.
In the musical instrument playing aid creation device of the present invention, in order to represent the note information without omission, five 1-byte alphanumeric symbols such as "C4 // 4", "C4 # * 8" and "QQ / * 2" are used. The predetermined input code consisting of a combined character string is adopted.
The first three letters "C4 /" of "C4 // 4" in the above input example represent the pitch information 35 indicating the tone of C4 (262 Hz), the next one letter "/" represents a single tone and the last one The letter "4" represents note value information 36 indicating a quarter note.
“C4 #” of “C4 # * 8” in the second example above represents the pitch information 35 indicating the C # 4 tone (277 Hz) in the same manner as described above, and the next “*” represents continuous tones etc. The last "8" represents note value information 36 indicating an eighth note.
In the case of a continuous note that extends a sound by connecting a plurality of notes in the note symbol, the continuous note or the like means the case where there is a dot and the case where the note value of the entire note is indicated in this device. Represents the presence / absence information 37 of continuous sound. The tone value of the musical tone is determined by the tone value information 36 and the presence / absence information 37 of the continuous sound.
“QQ /” of “QQ / * 2” in the third example above represents a rest, “*” represents a continuous tone, “2” represents a two-minute rest, and “QQ / *” in this input example "2" represents the above-mentioned total rest two consecutive rests for two minutes.
The input music information 20 is stored in the internal storage device or the external storage device. (Step 2)
In FIG. 2, it is stored in the internal storage device of the computer 5.

(Music information selection process)
Necessary information is selected from the stored music information 20 and sent to the next step. (Step 3)

(Step of separating music information into bibliographic information and musical tone information)
The music information 20 is separated and extracted into bibliographic information 21 and musical tone information 22. (Step 4)
As described above, the music information 20 of the present invention includes the type of musical instrument, song title, tone, beat, tempo, etc. as the bibliographic information 21, and as the tone information 22, the pitch, note value, presence or absence of coupled tones, rest Contains note information such as
The two different pieces of information are distinguished by the difference in the position of the input column and the difference in the number of bytes of the input character (bibliographic information 21 is a 2-byte character and musical tone (musical note) information 22 is a 1-byte character).

(Step of separating and extracting each information from bibliographic information)
Identify the type of instrument (Step 5)
Since the number, the direction, and the marks in the prepared indicator operating symbol display frames differ depending on the type of instrument, the number of indicator operating symbol display frames is determined based on the type information of the instrument in steps 6 and 7 described later. Acquisition of musical instrument type information for selecting an in-frame mark of a musical instrument operation symbol and a musical instrument operation symbol.
The musical instrument operation symbol 23 (hereinafter, abbreviated as "musical symbol") is generally synonymous with the musical tone constituting unit 24 constituted by the frame 25 and the mark 26 in the frame, but the musical instrument symbol The term is used to mean "symbolizes the specific operation of a performance operator and displays the pitch".

Determine the number of musical symbol display frames (one musical tone constituting unit) (step 6)
As shown in the examples of FIGS. 4 and 5, the number of performance symbol display frames is obtained by adding 1 to the number frame (or tone frame) of the performance operators, and in the case of the trumpet 31, it is typical. The seven frames constitute one musical tone constituting unit 24, the recorder 32 constitutes the one musical tone constituting unit 24 with nine frames, and the electronic musical instrument having a toe input keyboard (hereinafter abbreviated as toe manipulating musical instrument 33) 7 The frame constitutes one musical tone constituting unit 24.
Select the in-frame mark 26 of the musical symbol 23 (step 7)
The musical symbol 23 represents the operation state by using a simple symbol (mark) 26 such as "●" or "◆", and the non-operation state is expressed by blank.
As for how to blow the trumpet (breathing), a frame dedicated to blowing 3 to 4 frames is prepared, and the drawing of the breath is expressed by writing the mark 26 in any frame.

Each item of bibliographic information 21 is held as a character string variable (step 8)
Since the bibliographic information 21 includes information such as the song title, key (basic sound), time signature, performance tempo and the like in addition to the type of the above-mentioned instrument, these items are included in the performance operation support tool 2 of each instrument. Each item of the bibliographic information 21 is held as a character string variable for convenience when inserting into a display location according to a display format or forming a print format.

(Step of acquiring and holding the amount of musical tone information from musical tone information)
The musical tone information amount 27 (the number of notes and rests) is acquired from the musical tone information 22 and held as a variable (step 9)
Since the present invention performs processing for displaying musical tones by connecting the musical tone constituent units 24 for one music piece, the musical tone information amount 27 (number of notes / rests) which is the repetition number of the musical tone constituent units 24 is acquired and held as a variable. Do.

(Step of separating and extracting pitch information and tone value information from musical tone information)
The musical tone information 22 is separated and extracted into pitch information 35, tone value information 36 and continuous sound presence / absence information 37 (step 10).
As described above, since the musical tone information 22 includes pitch information, tone value information 36, and presence / absence information 37 of continuous tones, one musical tone constituting unit 24 is separated and extracted one by one.

(Step of determining the musical instrument symbol of the tone component unit)
The musical instrument symbol 23 is determined based on the pitch information 35 of one musical tone constituent unit 24 (step 11).
Determine the hue of the mark 26 (step 12)
The number of frames 25 of the musical symbol 23 and the marks 26 in the frames may differ depending on the type of instrument, and the size of the marks 26 changes for each note value. Further, depending on the musical instrument, it may be preferable to color the mark 26 in the frame. 4 and 5, FIG. 4 shows examples of the musical symbol 23 and the connection state of three types of musical instruments. In the recorder 32 of FIG. 4 (2), the trumpet 31 of (1), and the toe control musical instrument 33 of (3) (also see FIG. 5) And the connecting direction 29 (Y direction) differ by 90 degrees. This is because there is a difference in the easy-to-read direction of the performance operation support tool 2 depending on the playing style of the musical instrument.

The size (point) of the mark 26 is determined from the tone value information 36. (Step 13)
Specifically, in the present invention, the area of the mark 26 ("●" in the above example) is set to be equal to the common ratio 2 of the note value as a reference indicating the note value.
As described above, the note value represented by the note is “1” for the entire note, half the note value for the half note, and the half note value for the half note for the quarter note, and the following eighth note, The sixteenth note and the thirty-second note define the note value in equal proportions.
In order to visually (intuitively) recognize this relationship, it is effective to change the amount of stimulation to the vision, that is, the area of the mark 26 in an equal manner. If the amount of stimulation for the vision is represented by the length of a one-dimensional bar, the display pitch or interval between marks changes frequently and it becomes very difficult to see, and at the same time, it can be displayed on a fixed area such as A4 size. The amount also decreases. On the other hand, in the performance operation support tool 2 according to the present invention, the mark 26 representing the tone value is a method of inserting a symbol such as "●" or "◆" with an aspect ratio of 1 or near 1 into a frame of a certain size. In addition to high visibility, it has an excellent feature that the filling density of musical tones that can be displayed within a certain area when displayed by printing or the like is high.
Specifically, when a mark 26 (●) corresponding to a quarter note is 12 points, a half note is displayed as a mark 26 of 17 or 18 points (area ratio twice), and an eighth note is 9 points The 16th note is displayed with a mark 26 of 6 points (1/4 area ratio).

The musical instrument symbol 23 using the mark 26 of the area ratio as described above can intuitively recognize the magnitude relation of the marks, and is very effective as a reference representing the tone value. Furthermore, the size (tone value) of the mark 26 is also due to the change in the area of the margin between the frame 25 of a fixed area and the mark 26 itself changing in area gradually and the change in the distance between the mark end and the frame side. The presence or absence of the fill in the frame 28 is determined on the basis of the information 37 on the continuous sound etc. which can be grasped accurately. (Step 14)
A combination of the pitch information 35, the tone value information 36 and the continuous tone information 37 determines the musical symbol 23 of one musical tone constituting unit 24 (step 15).

In FIG. 3, the broken line connecting S10 and S15 is a process that replaces the process of steps 10 to 14 described above and is a process outlined by a broken line with “OR” in FIG. In this processing, the operator symbol group created so as to correspond to all the tones (pitch + note value) is held in the storage area in advance, and each tone is compared with the operator symbol group to be applicable. It is processing to determine the operator symbol to be Therefore, the processes of steps 10 to 15 can be replaced with one process. Further, a part of the steps 10 to 14 may be performed in the process, and may be performed in combination with the process of the remaining steps. The merit of this batch processing is that processing operations can be performed in a short time with less processing (contrast processing) if a storage area can be secured.

(Concatenation of musical symbol of musical tone composition unit)
The above steps 10 to 15 are repeated from the first tone to the last tone based on the tone information amount 27 of the above step 9 (step 16)
As described above, the processes of step 10 to step 15 may be determined sequentially, or a group of musical symbol 23 may be created in advance as data of a musical symbol group and selected from them. Moreover, the combination of both may be sufficient.

(Step of displaying the processing result of all music information)
Write the bibliographic items 21 held as variables (step 17)
After completion of all the processing steps described above, the bibliographic items 21 and all the musical instrument symbols 23 and the names of each note are displayed, and the correction of errors and the style are prepared, and the process proceeds to the storing or printing process (step 18)
(Printing process of instrument playing operation support tool)
The printed matter of the musical instrument performance operation support tool 2 is obtained by monochrome or color printing with the printer 12 shown in FIG. 1 (see also FIG. 2) (step 19)

(Two-dimensional barcode added printed matter)
The device of the second embodiment is characterized in that a two-dimensional bar code 45 storing the music information 20 is printed on a part of the margin 6 of the musical instrument performance operation support printed matter 2 of the first embodiment. This invention facilitates sharing of the music information 20 and extremely facilitates the input of the music information 20 in a personal computer, a mobile computer or the like. The invention of this embodiment is characterized in the process of the steps shown in S7 to S14 in FIG.

Music information input step (S1, S2), music information selection step (S3), step of separating music information into bibliographic information and musical tone information (S4), musical tone information amount acquisition (S5), bibliographic items as character string variables Each step of the conversion (S6) shares data with that of the first embodiment.

(Step of converting music information into compressed code for two-dimensional barcode)
The musical tone information 22 is separated and extracted into pitch information 35, tone value information 36 and presence / absence information 37 of continuous sound. (Step 7)
The pitch information 35 is converted into one-character alphanumeric characters. (Step 8)
In the musical instrument playing support tool creation device of the present invention, the input or selected music information 20 is input using a predetermined musical tone code, and the pitch information 35 is one-byte character symbol three characters such as "C4 /". However, if this three-character pitch information 35 is expressed as compressed pitch information 41 to which any one of 62 characters of 0 to 9 A to Z a to z is assigned, it is data when barcoded. The amount is reduced to 1/3 and the reading accuracy is significantly improved.
A range of 5 octaves can be expressed by the above one-character conversion method.

Convert the tone value information 36 and the continuous tone presence / absence information 37 into one-character numbers (step 9)
Similarly to the above, the sound value information 36 and the continuous sound presence / absence information 37 of the input or selected music information 20 are 2-byte information of 1 byte such as “/ 4”, but the sound value information and continuous sound of these 2 characters The combination of the tone value information 36 and the continuous tone presence / absence information 37 is expressed by the compressed tone value information 42 of one character by using the compressed tone value information 42 assigned the presence / absence information to any one character of 16 characters from 0 to F. The amount of data in a two-dimensional barcode can be halved.

Connect the alphanumeric characters of the compressed pitch information 41 and the numerals of the compressed sound value information 42 (A to F are also regarded as numerals) to convert them into two-dimensional two-dimensional bar code compressed musical tone code information 43 Step 10)
The above steps 8 to 10 are repeated 27 times from the first tone to the last tone, without any delimiters, and a continuous compressed tone information character string 44 is created (step 11).
The bibliographic information 21 and the compressed continuous musical tone character string 44 are separated and joined (step 12)
Since the amount of data of the bibliographic information 21 is smaller than that of the musical tone information 22 (continuous compressed musical tone information character string 44), 2-byte characters including easy-to-read kanji are converted into data as they are.
In the decoding process on the reading side, each item of the bibliographic information 21 is provided with a CSV delimiter so that the character string variable can be easily separated, and the compressed continuous tone character string 44 obtained by converting the tone information 22 is one continuous character string Join as. Since the continuous compressed tone information character string 44 is a repetition of two characters, it can be easily separated and extracted to the tone information unit 43 on the decoding side.

(Bar code conversion process)
The compressed continuous musical tone character string 44 of the bibliographic information 21 and the musical tone information in step 12 is converted into a two-dimensional bar code 45 (step 13)

(2D barcode printing process)
The two-dimensional barcode 45 is printed at a predetermined position of the margin portion 6 of the musical instrument performance operation support tool 2 of the paper medium of the first embodiment to obtain the two-dimensional barcode addition performance support support tool 3 shown in FIG. 14)

(Restore barcode information)
As a supplementary explanation, as shown in FIGS. 8 and 9, the music information restoration process on the side from which the barcode is read is as follows.
(Separation and extraction of music information)
The bibliographic information processing department
Separating and extracting the music information into bibliographic information 21 (musical instrument, song title, key, beat, tempo) and musical tone information (compressed continuous musical tone character string 44);
Since each item of the bibliographic information 21 is separated in the CSV format, a step of holding each item as a character string variable;
Displaying the item of the bibliographic information 21 on the bibliographic information display unit of the display 8 such as the mobile computer 7;

(Decoding process of musical tone information)
The tone information processing unit
Obtaining a musical tone information amount (total number of notes and rests);
Separating and extracting tone information into compressed tone information and compressed tone value information;
In the above step, since the musical tone information of the two-dimensional bar code 45 is stored as the continuous compressed musical tone information character string 44 in which the compressed musical tone code information of two characters is continuous, the character string 44 is divided into two characters from the beginning. Store strings in an array. Alphanumeric characters from the beginning of each character string (compressed tone code information 46) stored in the array represent compressed pitch information, and one character at the end represents compressed tone value information.
Based on the bibliographic information 21, the pitch information 41 and the tone value information 42, music information display processing conforming to the device on the two-dimensional bar code reading side and musical tone generation processing as required are performed.
