Hereinafter, the performance assist display device and the performance assist display method according to the embodiment of the present invention will be described in detail with reference to the drawings.

(1) Configuration of Performance Support Device FIG. 1 is a block diagram showing a configuration of a performance support device including a performance assistance display device according to an embodiment of the present invention. The performance support device 100 of FIG. 1 generates an accompaniment sound and displays a score for a wind instrument.

A wind instrument has one or more operating units for controlling the pitch (pitch) of the generated sound. For example, the trumpet has a plurality of piston valves (first piston valve, second piston valve, and third piston valve) provided at a plurality of positions as a plurality of operating units, and the piston valve to be pressed is an operating position (a first piston valve, a second piston valve, and a third piston valve). Corresponds to the trumpet). The trombone has a slide tube movably provided at a plurality of positions as an operation unit, and the position of the slide tube corresponds to the operation position. With brass instruments, even with the same fingering, different overtones can be produced depending on how the finger is blown. The overtones in this case are also called performance harmonics or harmonics.

Here, a plurality of overtones are represented by the first overtone to the nth overtone (n is an integer of 2 or more). A sound having a frequency determined by the length of a wind instrument is called the first overtone, and is also called the fundamental tone. A sound having a frequency determined by a length of 1/2 of the pipe length is called a second overtone, and similarly, a sound having a frequency determined by a length of 1 / n of the pipe length is called an nth overtone. Since both ends of the brass instrument are free ends, the lowest frequency standing wave generated in the brass instrument has a belly-node-belly from one end to the other. The sound produced by the lowest frequency standing wave is the fundamental physics. The second lowest frequency standing wave has a belly-node-belly-node-belly. The sound produced by the second lowest frequency standing wave is the physical overtone. Similarly, the sound produced by the nth lowest frequency standing wave is the nth harmonic overtone in physics. For brass instruments, the physics fundamental, second overtone, ..., N overtone are called the first overtone, the second overtone, ..., The nth overtone in that order. Since one end of a woodwind instrument is a fixed end and the other end is a free end, the lowest frequency standing wave generated in a woodwind instrument has a node-antral from one end to the other. The sound produced by the lowest frequency standing wave is the fundamental physics. The second lowest frequency standing wave has node-ventral-node-antrum. The sound produced by the second lowest frequency standing wave is the physical third harmonic. Similarly, the sound produced by the nth lowest frequency standing wave is the physical (2n-1) overtone. For woodwind instruments, the physics fundamental, third overtone, ..., (2n-1) overtone are called the first overtone, the second overtone, ..., The nth overtone in that order. Since it is difficult to play the basic physics of a brass instrument, the first overtone, the second overtone, ..., The physics of the second overtone, the third overtone, ..., (n + 1) overtone, ... , Nth overtone may also be called. Similarly, for woodwind instruments, it is difficult to play the basic physics, so the physics 3rd overtone, 5th overtone, ..., (2n + 1) overtones are the first overtone, the second overtone, and so on. ..., sometimes called the nth overtone.

The operation score 120 includes an instrument figure 71 that schematically represents a wind instrument, and a plurality of line segments P1 to P3 corresponding to a plurality of operation positions of the wind instrument. The musical instrument figure 71 includes one or more operation units of a wind instrument. In the example of FIG. 6, the musical instrument figure 71 represents a trumpet. The plurality of line segments P1 to P3 are displayed so as to extend in the time axis direction from the plurality of operating positions of the wind instrument. In the example of FIG. 6, the lines P1 to P3 are displayed so as to extend parallel to the time axis direction from the first piston valve B1, the second piston valve B2, and the third piston valve B3 of the trumpet. The operation position information 72 indicating the operation position is displayed on the plurality of line segments P1 to P3 corresponding to the operation position. In the example of FIG. 6, the operation position information 72 is a thick line segment extending in the time axis direction. In the example of FIG. 6, the first piston valve B1 and the third piston valve B3 are pressed corresponding to the sound name "D", and the first piston valve B1 and the second piston valve correspond to the sound name "E". It is shown that B2 is pressed and the first piston valve B1 is pressed corresponding to the sound name "F".

The overtone score 130 includes a plurality of line segments L1 to L5 corresponding to the first overtone to the nth overtone (n is an integer of 2 or more). The plurality of line segments L1 to L5 are displayed so as to extend parallel to the time axis direction. In the example of FIG. 6, five line segments L1 to L5 corresponding to the first to fifth overtones are displayed, but the number of overtones is not limited to this. At the left end of the plurality of line segments L1 to L5, an overtone symbol 81 indicating that the overtone score 130 is displayed is displayed. The overtone designation information 82 is displayed on the line segment corresponding to the overtone of each note name among the plurality of line segments L1 to L5. In the example of FIG. 6, a number representing the fingering number is used as the overtone designation information 82.

In addition, the performer can recognize the overtone and fingering for playing the pitch represented by each note name by the overtone score 130.

(5) Transposing table Since a wind instrument is a transposing instrument, the actual sound produced differs depending on the type of wind instrument when a sound with the same note name in the same score is produced. Therefore, it is necessary to transpose when creating the score of each type of wind instrument. FIG. 7 is a diagram showing an example of a transposition table.

The transposition table 90 of FIG. 7 shows the tones and clefs of each type of wind instrument, and also shows the transposition amount and key signature corresponding to each tonality at the time of transposition. For example, the tonality of the trumpet is "B ♭". When transposing a C major score to a B ♭ key score, raise each note by two semitones and add two "#" key signatures.

When the type of wind instrument is changed by the instrument type setting unit 57 of FIG. 2, the operation position / overtone specifying unit 53 changes the score information based on the transposition table 90, and the score information according to the type of wind instrument after the change. The transposition is made to, and the operation position and overtone corresponding to each pitch are specified based on the musical score information after the transposition. Further, the display information generation unit 54 generates the display information DI according to the type of the changed wind instrument. The transposition table 90 may be held by the operation position / overtone specifying unit 53, or may be stored in the storage device 40 of FIG.

(6) Performance Assist Display Method and Performance Assist Display Program FIGS. 8 and 9 are flowcharts showing a performance assistance display method in the performance assistance display device 1. The performance assistance display method of FIGS. 8 and 9 is performed by the CPU of the processing device 50 of FIG. 1 executing a performance assistance display program stored in the ROM or the storage device 40.

First, the performance information acquisition unit 51 of FIG. 2 acquires the musical score information in the performance information PI stored in the storage device 40 of FIG. 1 (step S1). Further, the instrument type setting unit 57 sets the type of the wind instrument (step S2). In this case, the musical instrument type setting unit 57 may set the type of wind instrument based on the operation of the operation unit 10 of FIG. 1 by the user. When the musical score information includes the type of wind instrument, the musical instrument type setting unit 57 may set the type of wind instrument based on the musical score information acquired by the performance information acquisition unit 51. Further, when the musical score information is the audio data of the performance song, the musical instrument type setting unit 57 may set the type of the wind instrument based on the audio data.

Next, the operation position / overtone specifying unit 53 specifies a basic fingering number corresponding to each pitch included in the score information based on the conversion table 52 (step S3). Further, the operation position / overtone specifying unit 53 determines whether or not there is a replacement finger number for the pitch based on the conversion table 52 (step S4). If there is a replacement finger number, the operation position / overtone identification unit 53 determines whether or not the replacement finger number should be selected according to the phrase (step S5). For example, based on the fingering numbers corresponding to the pitches before and after the pitch, the fingering number should be selected when the fingering change is smaller in the fingering number than in the basic fingering number. It is determined that there is. Specifically, the basic fingering number or the replacement fingering number is selected so that the change in the bit of the binary fingering number is small. In this case, after the fingering number corresponding to the next pitch is specified, it is determined whether or not the replacement finger number should be selected for the previous pitch. Alternatively, when the replacement finger selection unit 55 has selected the replacement finger number based on the operation of the operation unit 10 in advance, the operation position / overtone specifying unit 53 should select the replacement finger number. judge.

When the replacement finger number should be selected, the operation position / overtone identification unit 53 changes the specified fingering number to the replacement finger number (step S6). If there is no replacement finger number in step S4 or if the replacement finger number should not be selected in step S5, the process proceeds to step S7.

Further, the operation position / overtone specifying unit 53 specifies the overtone corresponding to each pitch based on the conversion table 52 (step S7). At this time, the operation position / overtone specifying unit 53 determines whether or not there is an alternative fingering number and overtone corresponding to the pitch based on the conversion table 52 (step S8). If there is an alternative fingering number and overtone, the operating position / overtone specifying unit 53 determines whether or not an alternative fingering number and overtone is selected by the overtone selection unit 56 (step). S9). When an alternative fingering number and overtone is selected, the operation position / overtone identification unit 53 changes the basic fingering number and overtone to the alternative fingering number and overtone (step S10). ).

After that, the display information generation unit 54 generates display information of the operation score 120 based on the specified fingering number and time information TI (step S11), and generates the specified fingering number, overtone, and time information TI. Based on this, the display information of the overtone score 130 is generated (step S12). Further, the display information generation unit 54 causes the display device 60 to display the operation score 120 by outputting the display information of the operation score 120 (step S13), and outputs the display information of the overtone score 130 to display the display device 60. Display the overtone score 130 (step S14). Further, the display information generation unit 54 causes the display device 60 to display the current information 150 indicating the current performance location based on the time information TI (step S15).

Next, the operation position / overtone specifying unit 53 determines whether or not the type of the wind instrument has been changed by the instrument type setting unit 57 (step S16). If the type of wind instrument has not been changed, the operation position / overtone identification unit 53 returns to step S3. As a result, the processes of steps S3 to S16 are performed for the next pitch.

When the type of the wind instrument is changed in step S16, the operation position / overtone specifying unit 53 transposes the musical score information based on the transposition table 90 of FIG. 7 (step S17), and returns to step S3. As a result, the operation score 120 and the overtone score 130 corresponding to the changed type of wind instrument are displayed.
