Description

[Detailed Description of the Invention] The present invention relates to teaching materials for learning musical scales, and its purpose is to enable the user to easily understand the structure of musical scales when practicing musical scales on a piano or an organ.

Practicing scales on the piano or organ is one of the essential basic studies for those who want to play the piano or organ, but for young children and beginners, it is not easy to understand the scales themselves, and it is difficult to master them. It is.

Therefore, the present invention was devised to make it easier to understand the scale structure before starting actual fingering practice.

That is, the present invention has a back side plate with a keyboard section defined in the same arrangement as the M-board of a piano or organ, and a front side plate that overlaps this back side plate and is slidable relative to this back side plate. The front plate is provided with transparent parts corresponding to each scale at appropriate intervals in the sliding direction, and the area around the transparent parts of the front plate is semi-transparent, and each transparent part is connected to the keyboard. When you hit a certain part, you can identify the scale that matches that part.

The present invention will be explained below based on drawings showing an example of implementation.

In the figure, 1 is a back plate with a keyboard part 2 arranged in the same manner as the keyboard of a piano or organ.
The two plates 1a and lb overlap each other, and the plate 1a that overlaps with the soldier side is made of transparent material.
The keyboard section 2 is sandwiched between the two plate bodies 1a and lb.

The position of this keyboard section 2 is set so that it is located slightly above the center when the back plate 1 is erected.

Reference numeral 3 denotes a front plate that overlaps the back plate 1 and is slidable on the back plate 1 along guides 4, 4 on both sides of the back plate 1, and the front plate 3 is transparent. It is constructed by stacking two plates 3a and 3b made of wood on top of each other, and is made to have approximately the same size as the back plate 1.

Reference numeral 5 denotes a scale table having cutouts 6 corresponding to each scale so as to be positioned at appropriate intervals in the sliding direction of the front plate 3;
It is sandwiched between the plates 3a and 3b, and the area around the cutout 6 of the scale table 5 is semi-transparent.

Each of the side cutouts 6 is used by abutting against the keyboard section 2, and the dimensions of the cutout sections 6 are formed to match the dimensions of the keyboard section 2.

7, the musical scales of each cutout part 6 are C major, G major, D major, A major, E major, Mouth major, and F major from the top.

Also, in the scale table 5, by turning back the front plate 3, the left and right sides of each cutout part 6 are reversed, and as shown in FIG. The keys are major, E-flat major, A-flat major, D-flat major, and G-flat major.

Although each side cutout 6 is formed so that a keyboard for the 10th note can be seen, the two keyboards from the right in FIGS. 3 and 4 are unnecessary.

Therefore, when using a scale learning material with such a structure, the front plate 3 is slid against the back plate 1, and the cutout 6 of the scale of the scale you want to know, for example, G major, is applied to the keyboard part 2. As shown in FIG. 3, the keyboard section 2 of the G major scale can be clearly seen through the cutout 6, allowing the user to know the scale.

The remaining keyboard section 2 can be seen through the semi-transparent section.

Moreover, by turning the front plate 3 over, it can be used as shown in FIG. 4, and the position of the cutout 6 is determined so that it can be used on both the front and back sides.

By the way, there are major scales and minor scales.

There are three types of minor scales: natural minor scale, harmonic minor scale, and melodic minor scale.The natural minor scale is the 3rd, 6th, and 7th notes of the major scale, and the harmonic minor scale is the 3rd, 6th, and 6th notes of the major scale. of,
To create a melodic minor scale, simply lower the third note of the major scale by a semitone.

However, the descending melodic minor scale must be a natural minor scale.

Therefore, auxiliary keyboards 8 to 10 as shown in FIG. 5 A to C are used to lower the pitch by a semitone to obtain each of the minor scales.

This is a keyboard in which the ward portions in Fig. 5 A to C are unnecessary.

For example, to create a minor scale with a minor harmonic tone, use the auxiliary keyboard 8 shown in Figure 5A to hit the third and sixth notes as shown in Figure 6.

If the 3rd, 6th, or 7th note is already a black key or a semitone, you can use the auxiliary keyboards 9° and 10 shown in Figure 5 and C.

To create a D minor harmonic minor scale, the third note is a black key, and to lower the black key by a semitone, use the auxiliary keyboard 9 shown in Figure 5.

The auxiliary keyboard 10 shown in FIG. 5C may be used when the pitch to be lowered is already a semitone.

In the embodiment described above, the back side plate 1 and the front side plate 3 are made to have approximately the same size, and the front side plate 3 is used by sliding on the back side plate 1. 1 may be made smaller so that only the portion where the keyboard section 2 is provided, and the back side plate 1 may be made to slide with respect to the front side plate 3.

Further, the keyboard portion 2 may be printed directly on the back side plate 1, and the cutout portion 6 may be formed directly on the front side plate 3.

In that case, it is better if the front plate 3 is made of a translucent material.

The teaching material for musical scales of the present invention can be implemented as described above, and allows children to easily grasp the musical scale structure, and also allows them to become familiar with the musical scales like playing cards on a desk.
