  Some music score creation software includes a function for automatically editing an electronic music score based on a rule / pure rule. For example, it is a function that automatically determines the interval (spacing) of notes and the direction of note tails when pasting notes on a staff notation displayed on the screen, based on the music / purse rules. According to this editing function, it is possible to easily create a beautiful score in accordance with the music / pure rule even if the knowledge about the music notation is scarce.

  By the way, when inputting notes / rests of the same phrase, selecting and copying and pasting symbols or copying and pasting in units of measures is more efficient than inputting notes one by one.

  However, there is a problem that it takes time and effort because it is necessary to use the mouse halfway when operating only with the keyboard as in step input, that is, when inputting one note at a time in non-real time.

  Also, if the pitch is different in measure copy and paste, it takes time to correct the pitch of each note / rest after pasting, greatly reducing the amount of input operation when inputting notes on an electronic score. There was a problem that it was not possible.

  The present invention has been made in view of the above-described problems, and it is an object of the present invention to greatly reduce the amount of input operation when inputting notes on an electronic score.

  The note input device of the present invention uses a pointing device to read out the music symbol and the font of the note from the music symbol storage means, and corresponds to the position on the display screen instructed using the pointing device. A note input device that develops image data of the font in an image memory, the note input using the pointing device, the note at the beginning of a phrase already input in the score, or other Match detection means for detecting a match with a note at the beginning of a phrase of a musical score or a note at the beginning of a phrase registered and recorded in a storage unit, and by using the match detection means, Input predicting means for predicting an input part following the head part of the phrase when it is determined that they match Music symbol display means for displaying the continued input portion predicted by the input predicting means on a display device; and prediction result availability input means for accepting whether the continued input portion displayed on the display device is acceptable from a user; And music symbol input means for determining a predicted music symbol displayed on the display device in accordance with whether or not it is input via the prediction result availability input means.

  The note input program of the present invention uses a pointing device to read out music symbols and note fonts from the music symbol storage means, and corresponds to the position on the display screen instructed using the pointing device. A note input program for causing a computer to execute image data of the font in an image memory, wherein a note input using the pointing device and a head portion of a phrase already input in a score A match detection step of detecting a match with a note, a note at the beginning of another musical score phrase, or a note at the beginning of a phrase registered and recorded in the storage unit; and in the match detection step, The beginning of the phrase when it is determined to match the beginning of the phrase An input prediction step for predicting a continuous input portion of minutes, a music symbol display step for displaying the continuous input portion predicted in the input prediction step on a display device, and the continuous input displayed on the display device A prediction result availability input step for accepting whether or not a portion is acceptable from a user, and a music symbol input step for determining a predicted music symbol displayed on the display device in accordance with the availability of input in the prediction result availability input step. It is made to perform.

  According to the present invention, when a note is input, a match between the input note and the note at the beginning of the phrase already input in the score is detected, and matches with the beginning of the phrase. When it is determined that the input portion is continued from the beginning of the phrase, the continued input portion is displayed on a display device, whether the continued input portion is accepted or not is accepted from the user, and the acceptance is accepted. Since the predicted music symbol displayed on the display device is determined, the user can easily input the music symbol of the same phrase simply by inputting whether or not the predicted music symbol is displayed on the display device. This makes it possible to greatly reduce the amount of input operation when inputting music symbols on the score.

The function stored in the function button storage unit 17 is set to be valid / invalid according to the position of the cursor and the command from the mouse 7, and the setting content is input from the function instruction unit 19 to the music symbol development unit 18. Thereby, the font data is edited by the effective editing function, and the image data is developed in the image memory of the music symbol developing unit 18.

  The designated key detection unit 22 determines whether or not a designated key (for example, a shift key) is included among the depressed keys by the key scan circuit 11. When the designated key detection unit 22 detects that the designated key is included, the function inversion unit 20 is read from the function button storage unit 17 to the function instruction unit 19 and input to the music symbol expansion unit 18. Reverse the validity / invalidity of.

  The editing function selected as invalid is stopped, and automatic editing is performed only by the valid editing function. In this way, image data such as music symbols edited by the effective editing function and developed in the music symbol expansion unit 18 is synthesized with the image data of the staff notation stored in the staff storage unit 21 and input to the display device 5. . The position on the display screen is managed by XY coordinates where the upper left corner is (0, 0).

  Next, a specific example will be described. FIG. 3 is a diagram showing a display example of the display device 5. The display device 5 displays a score creation mode screen. At the top of the screen 24, a menu bar 25 and a tool bar 26 are provided. Only a part of the buttons of the menu bar 25 and the tool bar 26 are shown because they are not the main part of the present invention. A score drawing range 27 is provided on the right side of the screen 24. In the drawing screen, staffs are arranged in advance in multiple stages (in this example, 5 stages). Here, an example is shown in which clefs are displayed on the staff. However, the clef can be arbitrarily changed by the creator, and the clef can be arbitrarily set as an initial screen only for the staff. May be.

  On the left side of the screen 24, a palette 28 including music symbols and editing commands is displayed. The pallet 28 includes a plurality of tag sheets 28-1, 28-2, ..., 28-9. The top two tag sheets 28-1 and 28-2 accommodate the ones that are frequently used for the creation and editing of musical scores to facilitate the selection of symbols. On the screen 24, a cursor 29 movable with the mouse 7 is displayed.

  An example of creating a score will be described with reference to FIGS. First, the score creation mode screen of FIG. 3 is displayed on the display device 5. This screen is displayed according to the data read out from the storage units 16, 18, and 21 in response to the instruction by clicking “score creation mode” on a mode selection screen (not shown).

  Subsequently, a musical symbol or the like is entered on the staff in the drawing range 27. As shown in FIG. 4 (a), since the musical score 30 on which the clef 31 has already been drawn as an initial display is displayed in the drawing range 27, a symbol indicating the time signature is drawn. In this case, the cursor 29 is moved to the tag sheet 28-8 using the mouse 7 and clicked. Then, the mouse 29 is clicked with the cursor 29 placed on one of the time signatures (not shown) included in the tag sheet 28-8. In this example, 4/4 time (C) is selected.

  Then, the mouse 29 is clicked with the cursor 29 placed on the staff 30 in the drawing range 27. As a result of this operation, as shown in FIG. 4B, a 4/4 time symbol 32 is drawn on the staff 30. It should be noted that the cursor 29 creates an editing program so that a drawing operation is drawn at the correct position when a click operation is performed in accordance with the position on the staff 30 where the time signature is to be placed.

  Next, draw a note. Move the cursor 29 to the quarter note button 33 on the tag sheet 28-1 and click the mouse 7. Then, move the cursor 29 to the desired position on the staff 30 and click the mouse 7 to click the quarter note. 34 is drawn on the staff 30.

  In addition, when the cursor 29 is moved to another position on the staff 30 and notes with notes are consecutive, such as eighth notes, instead of displaying the notes, editing is performed to connect the notes with a string. Set the function. The toggle button 36 of the tag sheet 28-1 has a function of switching the automatic beam function from valid to invalid or invalid to valid each time it is clicked.

  If the eighth digit 38, 39 is drawn on the staff 30 using the eighth note button 37 of the tag sheet 28-1 with the automatic beam function enabled, the eighth note 38, 39 is automatically generated. Combined and edited into a note 40.

  In this way, when notes are input one after another, the notes are drawn on the staff 30 and the music symbol storage unit 16 stores fonts such as music symbols (note / rest group). The music symbol expansion unit 18 of the present embodiment has a note input prediction mode, and when set to the note input prediction mode, performs prediction display when a note is input.

Next, the processing procedure of the prediction display of the note input device of this embodiment will be described with reference to the flowchart of FIG.
In step S501, it is determined whether or not a note has been input. If a note is input as a result of this determination, the process proceeds to step S502, and the note number, note value, and position on the staff 30 are detected for the note input in the score, that is, the already input note.

  Next, proceeding to step S503, it is detected whether the note value and position detected at step S502 and the head portion of the phrase already input on the staff 30 and stored in the musical symbol storage unit 16 match. To do. This coincidence detection can be performed at the beginning of a phrase already entered in the score, at the beginning of another phrase, or at the beginning of a phrase that has been registered and recorded in the memory. This is done by detecting a match with. Specifically, coincidence detection is performed based on the position of the staff on the staff and the note number, the length of the sound, etc., for the notes of several beats at the beginning of the phrase. As a result of the coincidence detection in step S503, if they coincide, the process proceeds to step S504, and if they do not coincide, the process returns to step S501.

  In step S504, the phrase already input on the staff 30 and stored in the music symbol storage unit 16 is read, and the music symbol of the input part following the input note is predicted. Next, it progresses to step S505 and the music symbol estimated by step S504 is displayed on the display apparatus 5. FIG.

  Next, in step S506, the user is asked to determine whether the prediction is OK. If the result of this determination is OK, the process proceeds to step S510, and if not, the process proceeds to step S507.

  In step S507, the user is asked to determine whether to display another prediction result. If the result of this determination is YES, the process proceeds to step S508. In the case of NO, the prediction input is not performed and the process returns to step S501.

  In step S508, a prediction result different from the prediction result displayed in step S505 is selected and displayed on the display device 5. Thereafter, the process proceeds to step S509 and the user is asked to determine whether or not the prediction is OK. If the result of this determination is YES, processing proceeds to step S510, and if it is NO, prediction input is not performed and processing returns to step S501.

  In step S510, a process of sequentially confirming predicted music symbols, which are prediction results of step S504 or step S508, as input notes is performed. As a result of this processing, when the third measure indicated by reference numeral 400 in FIG. 4 (a) has been input, the candidate portion that is described lightly after the third beat is changed to a normal reference numeral 401 in FIG. 4 (b). Entered as shown in the description.

  In step S508, a method of displaying a list of candidates indicated by reference numeral 403 in FIG. 4D and candidates indicated by reference numeral 404 in FIG. In that case, the user can select from a plurality of candidates displayed on the display device 5 and input it to the staff 30. In FIG. 4E, the candidate indicated by reference numeral 404 is a phrase that has been registered in a phrase and recorded in advance in the music symbol storage unit 16, as indicated by reference numeral 402 in FIG.

  In the above-described embodiment, when the coincidence detection is performed for the notes of several beats at the beginning of the phrase, the phrase or the note number and the note length on the staff are completely coincident with each other. An example is shown in which it is determined that the first part of each matches. However, it can also be determined that the phrases are the same from the relative pitch and length of the notes for several beats at the beginning of the phrase.

  That is, the first measure and the second measure are the same in relative pitch and sound length, except that they differ by two semitones. In this case, after inputting the first measure, it is possible to display a candidate at the point when the second measure is input halfway. For example, as shown in FIG. 4 (f), when up to three notes of the second measure are input, the notes “L” and “L” can be displayed as candidates as indicated by the broken note.

  As described above, in the present embodiment, when a note is input, the note value and position on the staff 30 of the input note are detected, and the detected note value and position are already input and stored as a musical symbol. The head portion of the phrase stored in the section 16 is compared, the portion to be subsequently input is predicted based on the comparison result, and the prediction result is displayed on the display device 5.

  This makes it possible to input notes with the same efficiency as selecting and copying and pasting symbols or copying and pasting in units of bars without using the mouse 7. The work efficiency of the input operation when inputting the incoming musical score can be greatly improved.
