Hereinafter, a music puzzle game providing apparatus, a music puzzle game providing method, and a recording medium on which the program is recorded will be described with reference to the accompanying drawings 1 to 13, according to a preferred embodiment of the present invention. In the following description, for the sake of clarity of the present invention, a description of what has been conventionally known will be omitted or simplified.

1 is a functional block diagram illustrating a configuration of a music puzzle game providing apparatus according to an embodiment of the present invention. 1, a music puzzle game providing apparatus 100 according to an embodiment of the present invention includes a memory 110, an input unit 120, a control unit 130, a display unit 140, and a sound output unit 150 .

The music puzzle game providing apparatus 100 is a device for providing a music puzzle game by using a music puzzle game program and executes a music puzzle game program recorded on a computer-readable storage medium, And may be a terminal such as a PC, a notebook, or a smartphone capable of providing a music puzzle game.

Here, the recording medium may be a magnetic recording medium, an optical recording medium, a carrier wave medium, or the like. Meanwhile, the music puzzle game providing apparatus 100 of the present invention receives and installs a music puzzle game program in the form of an app from a server (not shown), thereby providing a configuration for performing a communication function .

The music puzzle game program may be stored in the memory 110 or may be received from a server (not shown) that provides an external recording medium (not shown) or a music puzzle game program .

The input unit 120 may be a UI for receiving commands according to user operations. At this time, the command according to the user's operation may be an execution / termination command of a music puzzle game, a setting command and a selection command required when a music puzzle game is executed.

The control unit 130 can provide a music puzzle game by driving the music puzzle game program stored in the memory 110 when the music puzzle game is requested to be executed through the input unit 120. [ The control unit 130 reads a command according to a user's operation input through the input unit 120 to provide a music puzzle game, and controls each configuration as a whole.

The control unit 120 drives the music puzzle game program to provide a music list through the display unit 140. When one music is selected from the user, the control unit 120 visualizes the progress sound on the music score corresponding to the music, .

At this time, the controller 130 visualizes and matches the tones having different hues and heights according to the tone pitch of the progressive notes on the scoreboard, and selects a tile that can be selected by the user The number of paths, that is, the number of paths. At this time, the tiles can be arranged two-dimensionally or three-dimensionally. At this time, the shape of the tile is not limited, and may be polygonal or polygonal.

Referring to FIG. 2, the tile T may be composed of an octave region (a) representing an octave and a scales region (b) representing a scales. At this time, the octave region (a) visually expresses the elevation of the octave according to the heights (d1, d2), and the scales region (b) visually expresses the seventh scale by applying different heights and colors. At this time, the color can be a color value of a predetermined interval. Alternatively, it may be implemented in a rainbow color.

Alternatively, octaves and scales may be visually implemented as shown in FIGS. 3 and 4. In this case, the implementation of the scale is the same as in Fig. 2, but the octave can be visualized using the saturation and brightness. That is, although FIGS. 3 and 4 are shown two-dimensionally, the height of the scale region b for each scale of FIG. 2 is the same, and the saturation and brightness of the scale are used instead of the octave region (a) You can further visualize the octave region by applying it.

In the case of FIG. 3, the color H is implemented in a rainbow color, and the saturation S and the brightness B are adjusted by adjusting the saturation value or the brightness value based on the reference octave (S: 90, B: 90) . In the case of FIG. 4, the scale is visualized by the color value of the preset interval, and the elevation visualization of the octave is implemented in the same manner as in FIG.

The display unit 140 may display at least one tile that can be selected according to the music selected by the user under the control of the controller 130 and display the character on the tile selected by the user. Thus, the character moves according to the user's selection of the tile. At this time, the shape of the character is not limited, and it can be implemented as a polygon or a polygon.

Fig. 5 is a screen 1000 provided by the display unit 140, Fig. 6 is a musical score corresponding to the music selected by the user, and is not provided on the screen 1000, Respectively.

5 and 6, when one piece of music is selected by the user from the provided music list, the controller 130 selects at least one of the music pieces corresponding to the music according to the progressive sound length on the music sheet corresponding to the music One tile is displayed to allow the user to select.

The control unit 140 sets the maximum number of movement paths for the current progress sound on the scoreboard and can determine the number of movement paths for the current progression sound according to the set maximum movement score and the reference note. At this time, it is preferable that the maximum number of movement paths B is an odd number of 1 or more. Further, the reference note may be determined according to a quarter note (♩) or a reference note on the score. That is, when the reference beat is 4/4, the reference note becomes a quarter note (♩). When the reference beat is 6/8, the reference note becomes an eighth note (♪).

The control unit 140 determines the number of movement paths for the current progressive sound by dividing the maximum number of movement paths by three and the case where the number of the maximum movement paths is five or more, and provides the user through the display unit 140 by selecting the number of movement paths.

The control unit 140 can determine the number of movement paths for the current progressive sound based on the length of the reference note. In addition, the movement path through which the character 1 can move can be at least one of a straight line direction or a diagonal line direction with respect to the tile for the current progress sound. However, the movement path is set so that it can not go back to the previous progress sound, that is, the previous tile to which the character has been moved.

In addition, the movement path includes a tile corresponding to a sound to be proceeded, and tiles displayed on other paths can be provided by visualizing the HSB and the height at random. Here, the movement path is a path through which the character moves, and the number of movement paths is equal to the number of tiles disposed around the tile with respect to the current progress sound.

로 산출할 수 있다. 즉, 기준음표에 대한 이동 경로수는 최대 이동 경로 수의 중간 개수가 될 수 있다.Further, when the maximum number of movement paths is B (where B is an odd number of 3 or more), the number of movement paths M for reference notes is

. That is, the number of movement paths for the reference note may be an intermediate number of the maximum movement number.

 Referring to FIG. 7, when the maximum number of movement paths B is 3, the number of movement paths for the current progress sound can be calculated. At this time, a case where the reference note is set as a quarter note can be described as an example.

The control unit 130 sets the number of intermediate paths of the maximum number of movement paths B as the number of movement paths of the reference notes and compares the current progressed sound with the note lengths of the reference notes, In other words, if the current progressed note is a quarter note, the number of movement paths for the current progressed note is set to two. The controller 130 arranges two tiles at a straight line or a diagonal position of the tile corresponding to the current progress sound and one of the tiles may be visualized 1000b so as to have the HSB and height corresponding to the planned sound .

In addition, if the current progressed note is shorter than the reference note, the control unit 130 can visualize 1000a by setting the number of movement paths to one. That is, one movable tile can be arranged around the tile where the current character 1 is located.

Also, if the current progressed note is longer than the reference note, the control unit 130 can visualize (1000c) by setting the number of movement paths to 3. That is, three movable tiles can be arranged around the tile where the character 1 is currently located.

On the other hand, when the maximum number of movement paths B is set to 5 or more, the control unit 130 determines whether or not the current progressed sound is a current sound based on the length of the reference note, It is possible to calculate the number of movement paths k (x).

Here, A is the note length of the reference note, M is the number of movement paths of the reference note, K is the sound length of the current progressive sound, k (x) is the number of movement paths for K, B is the maximum number of movement paths, It can be an integer.

When the maximum number of movement paths is set to 7 and the reference note (reference note) is a quarter note, the number of paths by note length can be calculated as shown in Table 1 below.

Actual note length Reference sound / Sounds shorter than 4 Reference sound / 4 Reference sound / 2 Reference tone Reference tone * 2 Reference tone * 4 Reference sound * Longer than 4 Number of routes One 2 3 4 5 6 7 Note length formula

) The level interval (n) (n < -2) -2 -One 0 One 2 (n > 2)

8, since the number of movement paths for the reference note (reference sound) is the middle position of the maximum number of movement paths (seven), four movement paths are set, and the screen 140 A tile is arranged at a position of at least one of a diagonal line and a straight line of the tile T corresponding to the current progress sound at which the character 1 is located. In addition, the number of movement paths for each note length may be calculated based on the reference note, and may be provided through the display unit 140 as screens 1000a to 1000g.

That is, the controller 130 compares the note length of the current progressive note with the length of the reference note, and if the maximum number of movement paths is 5 or more, the control unit 130 can determine the number of movement paths for the current progressive note according to the conditional expressions. In addition, the controller 130 arranges tiles as many as the determined number of movement paths around the current progressive sound, so that the user can select and play the game.

5 and 6, in order to calculate the number of movement paths for the tile 11 corresponding to the current progression sound 10 in which the character 1 is located, the reference note is a quarter note and the maximum number of movement paths is 3, the number of movement paths for the reference note is 2. In addition, since the current progressive note 10 is a quarter note and has the same length as the reference note, the number of movement paths to the current progressive note 10 is 2. Accordingly, the tiles 21 and 22 can be arranged in a linear direction of the tiles 11. [ At this time, it is preferable that one of the tiles 21 and 22 has the HSB and the height corresponding to the planned sound 20. When the note 30 on the score is a progressive note, the length of the note becomes shorter than the reference note.

On the other hand, when the reference note is a quarter note, the maximum number of movement paths is seven, and the note 40 on the score 2000 becomes progressive, the number of movement paths of the reference note is four. Also, the number of movement paths for the length of the progressive sound is Log2A + 1 (where, A is the reference note length, that is, 1/4) is 5 as in the above table. Thus, five tiles are disposed in the circumferential direction of the tile 41 corresponding to the note 40 on the music score.

While the above embodiments have described a two-dimensional tile placement, the embodiment of FIG. 9 is for a three-dimensional tile placement. The controller 130 may arrange the tiles according to the number of travel paths and the tiles for the progressive sound on the score in consideration of the three axes (x, y, z). At this time, the description of the number of movement paths by note length on the music score has been described above, and the following description will be omitted.

9, the tile 70 corresponding to the previous progressed sound is moved to the tile corresponding to the current progressed sound, and the position of the character 1 is changed, and the movement path for the current progressed sound is shown three-dimensionally Can be confirmed.

10 and 11, it can be assumed that the reference note is a quarter note and the maximum number of movement paths is set to five. The control unit 130 can not display all musical notes on the musical score on one screen at the time of playing the music puzzle game, so that the music puzzle game can be provided on the continuous screen of the preset unit. The screen 1000 of Fig. 10 corresponds to the default setting unit 2 of the score 2000 of Fig.

The character 1 is positioned above the tile 61 corresponding to the current progress sound 60 on the score 2000 in Fig. 11 and the number of movement paths for the current progressed sound is calculated as 2 by the conditional expression, Respectively.

When a specific tile is selected from at least one tile provided for the current progressed sound, the control unit 130 outputs a preset sound corresponding to the color and height of the tile selected by the user through the sound output unit 150, It is possible to determine that the mission is successful if the preset tone corresponding to the color and height of the tile selected by the user matches the progress tone of the selected music.

Accordingly, the user can improve the musical learning effect by visually and audibly recognizing the length, beat, and height of the sound by completing the selected music through the game through the visualized musical note.

FIG. 12 is a flowchart illustrating a music puzzle game providing method according to an embodiment of the present invention.

If one music is selected by the user (S220), at least one tile that the user can select according to the music score corresponding to the music can be displayed on the screen (S230). At this time, at least one tile may be arranged around the tile corresponding to the current progress sound on the music score so that the user can select the movement path.

In addition, the character is displayed on the tile selected by the user (S240) so that the current position to be moved can be confirmed.

Next, the preset sound corresponding to the color and height of the tile selected by the user is output through the sound output unit 150 (S250). Here, the set tone is a predetermined scale according to the color and height of the tile.

Next, if it is determined that the set sound output in step S250 is identical to the current progress sound on the score, that is, if it is the same sound, it is determined that the mission is successful (S270) May be displayed.

Next, it is determined whether the music has been completed (S290). If the music is not finished, steps S230 to S290 may be repeated.

Here, if it is determined that the current progress sound is a success of the last sound on the score, it can be determined that the music is ended.

13 is a flowchart for explaining step S230 of FIG. Referring to FIG. 13, the maximum number of movement paths and reference notes for progressive notes on the score corresponding to the music selected by the user are set (S231).

Next, the length of the progressive note on the score and the length of the reference note are compared (S232). Then, according to the condition for calculating the number of movement paths per note length within the maximum number of movement paths based on the length of the reference note, (S233).

Next, the selectable tiles corresponding to the calculated number of travel paths can be arranged around the current tile in which the character is located (S234).
