[0027] Example
[0028] This embodiment provides a music tonality disk, such as Figure 1 and Figure 2 As shown, it includes a first disk 101 and a second disk 102 .
[0029] The second disk 102 is rotatably mounted on the first disk 101 and is arranged concentrically with the first disk 101. The second disk 102 has a twelve-tone equal temperament chromatic scale that is arranged at intervals along its circumference and distributed in a set order. By rotating the second disk 102, the seven pitches in the twelve-tone equal temperament chromatic scale are respectively arranged corresponding to the scale names. It should be noted that the twelve-tone equal temperament chromatic scale includes seven basic pitches (C, D, E, F, G, A, B), and five variable pitches (#C and bD), (bE and #D), (bG and #F), (#G and bA), and (#A and bB). In this embodiment, the twelve pitches divide the second disk 102 into twelve equal parts.
[0030] The first disc 101 has scale names (dol, re, mi, fa, sol, la, ti) arranged at intervals along its circumference and distributed in a set order. In this embodiment, the set order is arranged in a natural major key, that is, the pitch relationship between the scale names (dol, re, mi, fa, sol, la, ti) is full tone, full tone, semitone, full tone, full tone, full tone, semitone. In order to reflect the above pitch relationship, the arrangement positions of the scale names (dol, re, mi, fa, sol, la, ti) on the first disc 1 are as follows: the central angles between dol and re, between re and mi, between fa and sol, between sol and la, and between la and ti are all 60°, and the central angles between mi and fa, and between ti and dol are 30°. It should be noted that the set order can also be arranged in a major and minor scale relationship of harmony, melody, etc. For those skilled in the art, the intervals between each pitch level of the musical notation scale can be adjusted accordingly according to the corresponding set order. In this embodiment, the first disc 101 is a plastic part, and the musical scale names (dol, re, mi, fa, sol, la, ti) are integrally formed on the first disc 101, for example, they can be directly printed on the first disc 101, or the shape of the musical scale names can be directly formed when the first disc 101 is injection molded.
[0031] As a convertible implementation, the first disk 101 has musical notation scales or five-line musical notation scales arranged at intervals along its circumference and distributed in a set order.
[0032] As a convertible implementation, the scale name is detachably mounted on the first disc 101 by magnetic attraction or Velcro.
[0033] A positioning structure is provided between the second disk 102 and the first disk 101, such as Figure 3 As shown, the positioning structure includes a plurality of arcuate grooves 103 arranged on the upper surface of the first disk 101 and arranged corresponding to the musical notation scale or the five-line musical notation scale, and an arcuate protrusion 104 arranged on the lower surface of the second disk 102 and can be positioned and connected corresponding to the arcuate grooves 103. The edge of the second disk 102 is provided with a convex column 105 arranged perpendicularly thereto. The number of the convex columns 105 can be 1, 2, 3 or more, and those skilled in the art can flexibly select according to actual needs. The second disk 102 is assembled with the first disk 101 through the mounting structure, as shown in FIG. Figure 4As shown, the mounting structure includes: a first through hole 106, which is provided on the first disc 101; a second through hole 107, which is provided on the second disc 102 and is arranged corresponding to the first through hole 106; a connecting shaft 108, which connects the first disc 101 with the second disc 102 after passing through the first through hole 106 and the second through hole 107 in sequence; a connecting sleeve 109, which has a second pressing block 112 that abuts against the upper surface of the second disc 102, and a slot 110 for inserting the connecting shaft 8, and two buckling platforms 113 are provided on the inner wall of the slot 110, and an elastic hook 114 is provided on the top of the connecting shaft 108 and can be hooked and connected with the corresponding buckling platforms 113, and a first pressing block 111 that abuts against the lower surface of the first disc 101 is also provided in the middle of the connecting shaft 108. It should be noted that the first disc 101 and the second disc 102 can be cardboard or metal plates.
[0034] As a convertible implementation, the second disc 102 is detachably mounted on the first disc 101 by magnetism or Velcro.
[0035] In this embodiment, Figure 5 As shown, the music tonality disk can be installed on a writing board 115. The writing board 115 is formed with a slot (not shown) for the connecting shaft 108 to be inserted. The connecting shaft 108 is interference fit with the slot. The writing board 115 is provided with an area for writing various modes.
[0036] The working principle of the music tonality disk of the utility model is as follows (only C major and G major are used as examples):
[0037] When choosing C major (that is, C as the tonic), Figure 1 As shown, align the note level C on the second disc 102 with the dol on the first disc 101. At this time, (D, E, F, G, A, B) on the second disc 102 are respectively set to correspond to (re, mi, fa, sol, la, ti) on the first disc 101;
[0038] When the G major mode is selected (i.e., G is used as the tonic), the second disk 102 is rotated so that the pitch G on the second disk 102 is aligned with the dol on the first disk 101. At this time, (A, B, C, D, E, #F) of the second disk 102 are respectively set to correspond to (re, mi, fa, sol, la, ti) on the first disk 101.
[0039] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
