Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a chord structure main board (including a chord structure main instrument) displaying a 12-tone scale, a chord structure sub-board (including a chord structure sub-board) displaying one or more 12-tone scales, The present invention relates to a chord learning tool that allows you to learn major chords, minor chords, diminished chords, senbus chords, etc. using

0002

[Prior Art] Conventionally, each code or a combination of codes (
As a book for understanding the structure of chords, etc., each chord is illustrated or explained in a two-dimensional manner.

[0003] Prior literature aimed at this type of technique, that is, three-dimensional acquisition, includes the following, but as a general rule, the structure of each scale, each note name, each chord (combination of chords), etc. I can't find a three-dimensional structure of it.

[0004] However, as learning tools for learning by arranging teaching materials concentrically, there are a teaching material toy clock of Utility Model Publication No. 44-13146, and an addition/subtraction method and multiplication/division teaching tool of Utility Model Publication No. 51-1890.

[0005] Further, as a technical document that is in the same field as the present invention and has some similarities in its purpose, there is a guitar fingering position quick checker disclosed in Japanese Utility Model Application Publication No. 2-53065.

[0006]

[Problem to be solved by the invention] As mentioned above, the number of children and adults who want to understand music and play musical instruments is increasing. Also, even among those who can play musical instruments, it has been found that there are many who do not understand the mechanisms of scales, chords, etc., and in order to understand them, it is necessary to read hundreds of pages of books (specialized books). You can see many people giving up along the way.

[0007] This tendency is often seen especially when a person is just beginning to learn to play a musical instrument.

[0008] Therefore, there is a need for learning-based teaching materials that have a mechanism that allows students to understand basic scales, instrument chord progressions, or transpositions (movement of root notes) at a glance with simple operations. It is.

[0009] The above-mentioned document Utility Model Application Publication No. 2-53065 is
Since it is a sliding method, it is not possible to visually see the entire combination, and it is only possible to understand one point.

[0010] Also, it is not suitable for understanding a large number of chord structures or for understanding systematic musical scales, and its use is limited to one aspect only.

[0011]

[Means for Solving the Problem] Therefore, the present invention combines the mechanisms of each chord three-dimensionally, and specifically, freely combines a chord structure main board and a large number of chord structure subboards. In order to create a structure that allows you to understand the overall mechanism and multiple chord structures at a glance through free rotation, we adopt the following structure.

That is, the present invention provides a main disk-shaped chord structure displaying a 12-tone scale, and one or more disks displaying a 12-tone scale, which are provided concentrically overlapping the main chord structure board. It is a chord learning tool that consists of a chord structure sub-board and a chord structure sub-board.

[0013] Furthermore, the present invention employs the following structure in order to further develop the three-dimensional sense and provide an optimal structure as a teaching material for a large number of people.

[0014] A polygonal chord-forming main device rotatably provided on a pivot provided on a frame displaying a 12-tone scale, and one or several 12-tone chords adjacent to this and rotatably provided on the pivot. This is a chord learning tool consisting of a polygonal chord composition accessory displaying a scale.

[0015]

[Operation] Next, basic combinations of each code of the present invention will be explained.

In FIG. 1, a combination of major chords is shown, for example, the "C" sound of the main chord structure, the "Mi" sound of the first sub chord structure, and the "Mi" sound of the second chord structure. On the sub-board “
Select each of the "G" sounds and the direction of convergence (i.e.,
It is towards the center. ) as shown in the figure, a so-called C major code is constructed.

[0017] As a result, the C major chord becomes "do".
It is understood that it is composed of "E" and "G", and that this C major chord is the tonic of C major and constitutes one of the major triads.

Similarly, the "Re" sound on the main chord structure, the "F" (sharp) sound on the first sub-board of the chord structure, the "A" sound on the second sub-board of the chord structure, By selecting each and combining them in the convergence direction as shown in the figure, a so-called D major code is constructed.

[0019] As a result, the D major code becomes "Re".
It is understood that it is composed of "F" and "A", and this D major chord is the tonic of D major,
It is understood to form one of the minor triads.

[0020] As described above, by using this chord learning tool, you will be able to understand the mechanism and structure of other E major chords, G major chords, etc.

[0021] It should be noted that the C7 major chord is constructed by adding the "A" (sharp) of the second seventh chord sub-board of the chord structure to the C major chord, and that the third sub-part of the chord structure is added to the D major chord. It is also understood that by adding the "C" of the board, a D7 major chord is constructed.

FIG. 2 also shows a state in which the first subboard, such as the chord structure representing a minor chord, is shifted one frame (one frame) clockwise from the state shown in FIG. 1.

[0023] This forms a combination of minor chords. For example, you can change the sound of "C" on the main chord structure to "Re" (sharp) (and C (flat)) on the first sub-board of the chord structure.
It is also possible to replace it with ) and the sound of "G" on the second sub-board of the chord structure are respectively selected, and "Cm" is formed as shown in one frame of the first sub-board of the chord structure.

[0024] It is also possible to understand that "Cm" is composed of "do", "re" (sharp), and "so", and also to understand it as a dominant and a subdominant.

[0025] Similarly, we selected the "D" sound on the main chord structure, the "F" sound on the first sub-board of the chord structure, and the "A" sound on the second sub-board of the chord structure, respectively. In this state, "Dm" is composed as shown in one frame of the chord composition first sub-board.

[0026] It can be understood that "Dm" is composed of "re", "fa", and "la".

[0027] In this state, each minor chord is constructed by selecting the respective combinations of notes according to the indications such as "Gm", "Am", "Bm", etc. on the first sub-board of the chord structure. .

[0028] By adding "A" (sharp) of the second seven chord sub-board of the chord structure to the C minor,
By composing a C7 minor chord and adding "C" from the third sub-part of the chord structure to D minor, it becomes D.
The composition of the 7 minor chord can also be understood in the same way.

FIG. 3 also shows a state in which the chord structure second sub-board and the chord structure second seven-chord sub-board indicating diminished chords are shifted one frame clockwise from the state shown in FIG. There is.

As a result, a combination of diminished chords is formed. For example, the "C" sound on the first sub-board of the chord structure, the "R" (sharp) sound on the second sub-board of the chord structure, and the "D" sound on the second sub-board of the chord structure are combined. Each of the "F" (sharp) sounds on the third sub-disc is selected, and "Cdim" is configured as shown in one frame of the chord configuration second sub-disc. Similarly, we selected the "D" sound on the main chord structure, the "F" sound on the first sub-board of the chord structure, and the "G" (sharp) sound on the second sub-board of the chord structure. In this state, "Ddim" is composed as shown in one frame of the chord composition second sub-board.

[0031] In this state, according to the indications such as "Edim" and "Gdim" on the second sub-board of the chord structure,
Each diminished chord is constructed by selecting each of the notes in the combination.

It should be noted that the C7 diminished chord and D7 diminished chord are treated in the same manner as described above and are likely to be understood, so their explanation will be omitted.

Furthermore, the usage example shown in FIG. 4 employs a chord structure second ninth chord sub-board, and this chord structure second ninth chord sub-board is used to play C9 major chords, C9 minor chords, etc. I can understand.

FIG. 5 shows the chord learning tool of the present invention with other functions added. Specifically, the basic form of FIG. The distinction and even the key signature are displayed.

[0035]

[Example] An example of the present invention will be described below based on the drawings.

Sharp, C#), "R" (Sharp, D#), "F" (Sharp, F#), "G" (Sharp, G#), "
"A" (sharp, A#) is shown.

This chord structure main board 1 constitutes a major ring for displaying major chords.

A first sub-board 2, which is smaller than the main chord-forming board 1, is rotatably pivoted concentrically to the main chord-forming board 1.

This chord structure first sub board 2 is divided into 12 pieces 12, like the chord structure main board 1 described above,
The name of each note is also displayed.

[0040] Therefore, this chord structure first sub-board 2 constitutes a minor ring, and a minor chord is displayed within each piece.

Further, on the chord structure first sub-board 2, a second chord structure having a diameter smaller than that of the chord structure first sub-board 2 is arranged concentrically.
A sub-board 3 is rotatably pivotally mounted.

This chord structure second sub-board 3 is divided into 12 pieces 13, similar to the chord structure main board 1 described above.
The name of each note is also displayed.

[0043] Therefore, this chord structure second sub-board 3 constitutes a minor ring, and a minor chord is displayed within each piece 13.

[0044] Each piece 11, 12, 13 of the chord composition main board 1, the chord composition first sub-board 2, and the chord composition third sub-board 3...
... are converged in the direction of the pivot portion 4, and when the respective pieces 11, 12, 13, etc. match, the constituent chords are displayed in a substantially delta shape.

[0045] The chord structure second sub-board 3 is provided with 12 pieces 15 . Chord configuration second seven chord subboards 5 are provided concentrically.

As shown in the figure, this chord structure second seven chord sub-board 5 has a smaller diameter than the chord structure second sub-board 3, and since they are connected, they are structured to rotate at the same time (of course, (not limited to simultaneous rotation, the same applies hereinafter)
.

[0047] In each of the pieces 15, a seven code is displayed.
