Description

Interval disk

The utility model relates to teaching devices and can be used to teach solfeggio in music schools.

A device for teaching musical literacy is known (patent DE 20209186, IPC G09B 15/02), which contains two disks with a central pin with the possibility of rotation relative to each other. Each disk has cut windows for combining elements on the disks.

Known harmonic compass (RU 172163, IPC G09B 15/00, publ. 06/29/2017). The harmonic compass includes a palm-tone circle and a cadence ruler, which are placed on a common base, while a palm-shaped circle is formed from interconnected upper, common and lower bases, while the upper and lower bases are connected to a common base with the possibility of independent rotation relative to it, on the front surface of the common base there are elements containing designations of Ladofunctional structures, moreover, twelve holes located radially are formed in the common base, and the cadence line is formed from a common base and a tape connected to a common base on its back with the possibility of longitudinal movement relative to it and containing on its front surface elements denoting combinations of major and minor chords, combined according to the principle of the same name, and elements denoting satellite chords ordered with major and minor chords according to the scheme of quarto-fifth relationships, a system of holes corresponding to elements designating comb inations of major and minor chords, and elements representing satellite chords.

The well-known compass, among its capabilities, allows you to build intervals, but the set of intervals and notes for their construction is limited (at least by the fact that this model lacks a D # note (sharp). The order of notes in the model is also a classic increasing, which makes the model more complex, difficult to remember and imposes restrictions in the circle of tasks and production.

The objective of the claimed utility model is the creation of an easy-to-use, effective device for teaching solfeggio in music schools.

The technical result is the construction of intervals from any note up and down to the correct recording of notes (and not just sounds), without the need to calculate the task of constructing intervals.

The problem is solved, and the technical result is achieved by an interval disk containing a disk-shaped fixed part and a stencil mounted on a central pin with the possibility of rotation of the stencil relative to the fixed part, and on the fixed part there are elements in the form of notes in the order of a fifth circle - fa, do, salt, re , la, mi, si with the repetition of this sequence for flat and double-flat notes in one direction and sharp and double-sharp notes in the other, and the distance between the notes is fixed, while the stencil is marked with signifying small and large intervals, increased quart and diminished fifth - newts and two arrows, one of which goes from the center to the outside wheel, and the second hand goes to the center of the circle - inside.

According to the utility model:

the sequence of intervals on the stencil is repeated for reduced and increased intervals;

notes are designated as letters of the alphabet or Roman numerals, or pictures.

The essence of the utility model is illustrated by drawings, which depict the inventive interval disk.

Figure 1 - General diagram of the device.

FIG. 2 - explanatory photo (practical implementation of the device).

The disk contains (Fig. 1) the fixed part 1, the stencil 2, the central pin 3. Positions 4 and 5 indicate respectively the arrow going from the center (outward of the circle) and the arrow going to the center of the circle (inward).

The interval disk works as follows.

1. Stencil 2 is rotated so that arrow 4 going from the center (outward of the circle) points to the bottom note of the interval (to build the interval up) or arrow 5 going to the center of the circle (inwards) points to the top note of the interval (for building intervals down).

2. To find the second note, you need to find the designation of the desired interval on the stencil in the section next to the arrow (the stencil is divided into 2 sections - for intervals up and for intervals down). The note on the fixed part of the device in the sector of designation of this interval is the correct note (taking into account the correct alteration) for the selected interval from the note selected in paragraph 1.

Example: in FIG. 1 arrow 5, directed toward the center, shows the original note for plotting the interval down. In the set near this arrow, the corresponding positions of notes are marked for intervals downward from this note. The figure shows that the small third (m3) down from to (do) is la (la).

Thus, the use of an object makes it possible to solve the problem of constructing intervals by a simple motion of the stencil, which is classically solved in three computational steps:

finding the desired sound by modifying the original in accordance with the distance of the interval in semitones

finding the desired note by modifying the original note in accordance with the distance of the interval in notes

Alteration of the note to the desired sound using sharps or flats.

The effectiveness of mastering the subject is especially noticeable in children with a humanitarian mindset, because they have more developed imaginative thinking, and not the ability to derive and calculate in the head chains of formulas and transformations.

Using the disc allows you to build intervals from any note up and down to the correct recording of notes (and not just sounds), without the need to calculate the task of creating intervals.

Claims (3)
