Further, FIG. 2 is a flowchart illustrating the operation of the music generator 101 illustrated in FIG. 1. Further, FIG. 3 is a flowchart illustrating the operation of step S1 in the flowchart of FIG. Hereinafter, the configuration and operation of the music generator 101 will be described with reference to these figures. The method of exemplifying the procedure in FIGS. 2 and 3 is not limited to the music generator 101, and can be manually executed.
The music generation device 101 has a pressure distribution data acquisition unit 1 and a music data generation unit 2. The pressure distribution data acquisition unit 1 acquires pressure distribution data in a predetermined region on the earth surface (step S1). The music data generation unit 2 generates music data based on the acquired pressure distribution data (step S2). That is, the music generation device 101 is a device that converts the pressure distribution data into music data.

The barometric pressure distribution data is data related to barometric pressure distribution, including position data such as longitude and latitude of the center of high pressure and the center of low pressure in a predetermined region. The pressure distribution data may be input to the pressure distribution data acquisition unit 1 as numerical data, and as shown in the illustrated example, the weather map image data 10 which is the image data of the weather map is input to the pressure distribution data acquisition unit 1. May be good. In the latter case, the pressure distribution data acquisition unit 1 has an image data acquisition unit 3 and a pressure distribution data extraction unit 4 as shown in the illustrated example. The image data acquisition unit 3 acquires the weather map image data 10 (step S11), and the pressure distribution data extraction unit 4 extracts the pressure distribution data from the acquired weather map image data 10 by, for example, an image recognition method (step S11). Step S12).

From the weather map image data 10, the positions of the center of high pressure and the center of low pressure are together with symbols representing the center of atmospheric pressure such as "high", "low", or "H", "L" expressed in the weather map image data 10. The position of the center of the annular isobaric line can be specified by recognizing it by an image recognition method. If data on the height of the central pressure is required, it can be specified by recognizing the numerical values representing the atmospheric pressure attached to the isobars and recognizing the number of isobars up to the central pressure. .. Both are possible by well-known image recognition techniques. When the operation of step S12 is manually executed instead of the pressure distribution data extraction unit 4, there may be no technical method for image recognition.

The music data generation unit 2 makes the longitude of the center of high pressure and the center of low pressure correspond to the beat on the score, and the latitude corresponds to the pitch on the score, based on the acquired position data of the center of high pressure and the center of low pressure. By doing so, music data is generated. The generated music data can be reproduced as music by inputting it to the audio reproduction device 5.

The weather map image data 10 can be acquired, for example, on the web, and can also be acquired by scanning the weather map recorded on a recording sheet such as a print medium with a scanner. The music generator 101 may have a built-in scanner. The weather map recorded on a recording sheet such as a print medium can be regarded as representing the weather map data 10. Therefore, when the operation of step S11 is manually executed instead of the image data acquisition unit 3, acquiring the weather map recorded on the recording sheet itself is equivalent to acquiring the weather map data 10. do.

FIG. 4 is a block diagram illustrating a hardware configuration of the music generator 101. In the illustrated example, the music generation device 101 is composed of a personal computer 102, and includes a main circuit unit 12, an input device 11, a display device 13, and a hard disk device (HDD) 14. Further, the main circuit unit 12 includes a CPU (Central Processing Unit) 21, a ROM (Read Only Memory) 22, a RAM (Random Access Memory) 23, an interface (I / F) 24, and a reading device 25. Have.

The CPU 21 executes a program stored in the ROM 22 and the RAM 23. The ROM 22 stores, for example, a BIOS (Basic Input Output System) that starts the OS (Operating System) and sets the hardware immediately after the personal computer 102 starts up. The OS, applications, and the like stored in the hard disk device 14 are expanded in the RAM 23 as needed, and are executed by the CPU 21. The RAM 23 is also used as a work memory for temporarily storing data generated when the CPU 21 executes processing.

The interface (I / F) 24 has an IDE (Integrated Device Electronics) controller (not shown), a LAN controller, an input / output controller, and the like, and an external device such as an input device 11 is connected to the CPU 21 through these circuits. To. The CPU 21, ROM 22, RAM 23, and interface 24 are connected to each other through the bus line 26.

Generally, by installing a specific application program on a general-purpose computer device such as a personal computer 102 or a smartphone, the computer device operates as the music generation device 101 illustrated in FIG.

FIG. 5 is an operation explanatory diagram illustrating the operation of the music generator of FIG. In the illustrated example, music is generated based on weather map data in which the longitude range from 110 ° east longitude to 170 ° east longitude centering on Japan's land and the latitude range from 20 ° north latitude to 60 ° north latitude are set as predetermined areas. ing. The high pressure center and the low pressure center in the predetermined region are associated with the notes on the score. In the illustrated example, the longitude division 10 ° is associated with one beat of the score so that the musical tone progresses along the direction of the longitude from the west to the east. Further, the latitude division 5 ° is associated with the pitch of each chromatic scale so that the pitch increases along the direction of the latitude from the south to the north. The high pressure center and the low pressure center in the predetermined region are associated with the notes of the musical score so as to be the beats and pitches corresponding to the longitude division and the latitude division to which each belongs. If there is neither a cyclone center nor a cyclone center in a certain longitude section, there is no corresponding note, so the corresponding beat is equivalent to assigning a rest. If there are a plurality of high pressure centers or low pressure centers in the same longitude section, the beat becomes a double stop and a harmony is generated.

In general, the musical tone may progress from east to west, and one beat of the score may be associated with the size of a section other than 10 ° of longitude. Further, the pitch may be increased from the north to the south, and the chromatic scale may be associated with the size of the section other than the latitude of 5 °. Further, the predetermined region may be the entire earth surface.

FIG. 6 is an operation explanatory diagram illustrating the tonality setting with respect to the operation of the music generation device 101. The music data generation unit 2 counts the number of high pressure centers and the number of low pressure centers based on the position data of the high pressure center and the low pressure center, and determines the tonality of the music to be generated according to the difference. As a result, music data having different tonality depending on the difference between the number of high pressure centers and the number of low pressure centers can be obtained. In the illustrated example, if the numerical value N as a result of subtracting the number L of the center of low pressure from the number H of the center of high pressure is a positive number, the tonality that requires N pounds "#" is set and a negative number. If so, the tonality of the music is set to the tonality that requires -N variable symbols "♭". In the illustrated example, based on the weather map data 10 of FIG. 5, the number H of the center of high pressure is "3" and the number L of the center of low pressure is "4", so that the numerical value N is "-1" and the key is adjusted. Gender is set in F major or D minor, which requires one variable symbol "♭". Which one to select may be fixed to one side, or may be set by the music data generation unit 2 based on the user's operation, and as illustrated in FIG. 7 below, the high pressure center and the low pressure center. The music data generation unit 2 may set based on the average atmospheric pressure of.

FIG. 7 is an operation explanatory diagram showing an example of setting of major and minor keys with respect to the operation of the music generator 101. In this example, the barometric pressure distribution data acquisition unit 1 also acquires barometric pressure data at the center of high pressure and the center of low pressure in a predetermined region. Then, the music data generation unit 2 calculates the average central pressure Pa, which is the average value of the acquired atmospheric pressure data, and determines whether the average central pressure is larger than the standard atmospheric pressure Ps (for example, 1013.25 hPa on the ground surface). Determine whether the tonality is major or minor, depending on whether it is small. In the illustrated example, the average pressure Pa is calculated as 1017.7 hPa based on the weather map data 10 of FIG. 5, and since it is larger than the standard pressure Ps, the tonality is in major and is set in F major.
If it is determined that the tonality is in D minor, an accidental symbol "#" is added to the scale of "So" according to the normal minor scale, and the scale is raised by a chromatic scale. In the example of FIG. 5, it is in D minor, and an accidental symbol “#” is added to the scale of “C”. In this way, the major and minor scales are different.
