The piano score marking method, system, medium and device are used for sharing score marking information of the display device among different pianos.
As shown in fig. 1a, in an embodiment, the method for marking a piano score of the present invention includes the following steps:
step S11, inputting the score mark information through the input device, the score mark information being displayed on the display device of the first piano.
Specifically, when the display device is a touch screen, the input device is the display device or an interactive device connected with the display device; when the display device is not a touch screen, the input device is an interactive device connected with the display device. The display device is connected with the piano and used for displaying the music score. The interactive device is a mouse or a touch pad.
Step S12, defining any two vertical straight lines in each section of the music score as a y coordinate axis and an x coordinate axis respectively, establishing a rectangular coordinate system by the y coordinate axis and the x coordinate axis, and acquiring coordinates of the music score marking information in the rectangular coordinate system and a rectangular coordinate system establishment rule.
Specifically, as shown in fig. 1b, two arbitrary vertical straight lines are defined as a y coordinate axis and an x coordinate axis, respectively, in each bar of the musical score of the first piano having the display device, and a rectangular coordinate system is established with the y coordinate axis and the x coordinate axis. That is, the y1 coordinate axis and the x1 coordinate axis establish the same rule as the y2 coordinate axis and the x2 coordinate axis.
Specifically, the two vertical straight lines are two adjacent frames of the measure. Therefore, any two adjacent frames of the measure are used as a y coordinate axis and an x coordinate axis, the rectangular coordinate system establishment rule is more conveniently determined, and the rectangular coordinate system is conveniently established by the rectangular coordinate system establishment rule at each measure of the display device of the second piano. As shown in fig. 1c, the two adjacent frames are the left frame and the lower frame of each bar, the left frame is the y coordinate axis, and the lower frame is the x coordinate axis. And use left frame as the y coordinate axis, the lower frame is that the rectangular coordinate system is established to the x coordinate axis is most directly perceived convenient, and musical instrument register for easy reference mark information is most all in the first quadrant of rectangular coordinate system like this, and is most for the positive number, also convenient follow-up musical instrument register for easy reference mark information is in the calculation of rectangular coordinate system's coordinate also reduces the data bulk. As shown in fig. 1d, the two adjacent frames are the right frame and the lower frame of each section, the right frame is the y coordinate axis, and the lower frame is the x coordinate axis. The rectangular coordinate system establishing rule is that a rectangular coordinate system is established by taking which two vertical straight lines of each measure are respectively a y coordinate axis and an x coordinate axis. Specifically, the bar is bounded by respective left and right borders, and the score mark information falling within the left and right borders of the bar is the score mark information belonging to the bar. The coordinates refer to the coordinates of the rectangular coordinate system of the bar where the music score mark information is located.
And step S13, sending the rectangular coordinate system establishing rule, the section information of the coordinates and the coordinates to a second piano, so that the display device of the second piano establishes a rectangular coordinate system at each section according to the rectangular coordinate system establishing rule, and draws and displays the music score mark information based on the rectangular coordinate system and the coordinates which are the same as those of each section of the first piano.
Specifically, the rectangular coordinate system establishing rule is to establish a rectangular coordinate system with which two vertical straight lines of each measure are respectively a y coordinate axis and an x coordinate axis.
Specifically, the section information to which the coordinates belong means that identity identification information is set for each section for identifying different sections. The coordinates refer to the coordinates of the rectangular coordinate system of the bar where the music score mark information is located. Since the different bars are distinguished, for example, even if the layout position of the musical notation in which the fourth bar of the first piano is located is different from the layout position of the musical notation in which the fourth bar of the second piano is located, the identification information is set on a per-bar basis to find the corresponding bar, and the subsequent plotting and display of the musical notation mark information is performed on the basis of the same rectangular coordinate system and the coordinates as those of each bar of the first piano.
Specifically, the bar is bounded by respective left and right borders, and the score mark information falling within the left and right borders of the bar is the score mark information belonging to the bar.
For example, as shown in fig. 1e, upon inputting the score mark information through the input device, the score mark information is displayed on the display device of the first piano; the score mark information is that a circle is drawn on the first section of the score. Establishing a rectangular coordinate system by taking the left frame of each measure as a y coordinate axis and the lower frame as an x coordinate axis according to the rectangular coordinate system establishing rule; the section information to which the coordinates belong is a first section; the coordinates are all coordinates of the points making up the circle in a coordinate system of rectangular coordinates. And sending the rectangular coordinate system establishing rule, the section information to which the coordinates belong and the coordinates to a second piano, wherein the rectangular coordinate system is established by the display device of the second piano by taking the left frame as the y coordinate axis and the x coordinate axis as the lower frame in the first section, and as shown in fig. 1f, the notation mark information is drawn and displayed as a ring based on the same rectangular coordinate system and the coordinates as the first section of the first piano.
As shown in fig. 2, in one embodiment, the piano score marking system of the present invention includes an input module 21, a definition module 22 and a drawing module 23.
The input module 21 is used for inputting the score mark information through an input device, and the score mark information is displayed on a display device of the first piano.
The defining module 22 is configured to define any two vertical straight lines in each section of the musical instrument notation as a y coordinate axis and an x coordinate axis, establish a rectangular coordinate system with the y coordinate axis and the x coordinate axis, and obtain coordinates of the musical instrument notation marking information in the rectangular coordinate system and a rule established by the rectangular coordinate system.
The drawing module 23 is configured to send the rectangular coordinate system establishment rule, the bar information to which the coordinates belong, and the coordinates to the second piano, so that the display device of the second piano establishes a rectangular coordinate system at each bar according to the rectangular coordinate system establishment rule, and draws and displays the score mark information based on the rectangular coordinate system and the coordinates that are the same as those of each bar of the first piano.
Specifically, the two vertical straight lines are two adjacent frames of the measure.
Specifically, the two arbitrary adjacent frames are a left frame and a lower frame of each section, the left frame is a y coordinate axis, and the lower frame is an x coordinate axis.
Specifically, when the display device is a touch screen, the input device is the display device or an interactive device connected with the display device; when the display device is not a touch screen, the input device is an interactive device connected with the display device.
