Description

The present invention relates to a musical aid for clarifying Facts of harmony.

One of the tools often used in music is the so-called circle of fifths. By the facts of general music theory are depicted that all keys in fifths (five tones). From this fact and the phenomenon that major and minor keys differ in the position of the semitones the sequence of signs (cross sign = raised notes; loading sign = ernie third tones). So follows the key of C major (in the 00 o'clock position of the circle of fifths) up / right the key of G major, which starts 5 tones higher than C major. It follows D major, then A major etc. Down / left, the key of C major is followed by the key of F major, the 5 notes lower than C major, then B major, then E flat major etc. This general my well-known aid is in school books, music lessons, harmony handbooks etc. described. Working with the circle of fifths is limited to this; from the The fifth structure of the keys only the number of signs of a certain key read.

The object of the present invention was to provide an aid with which most Issues of harmony can be clarified. This should take into account be that the well-known circle of fifths, which is therefore well established by musicians The basis of the solution according to the invention should be. The facts to be presented yield directly from the circle of fifths.

The object of the present invention is achieved by an auxiliary means which Features according to claim 1 is characterized. The marked in the subclaims Neten embodiments are preferably configurations of the solution according to the invention. The aid consists of two disks, preferably circular disks, one above the other ordered and rotatably connected to each other at the center. Both discs are prints. The lower disc is divided into 12 different circle segments, which are clear at are separated from each other by black or colored dividing lines. This seg elements are assigned to the keys and are each divided into a ring. This segment rings each contain issues of general music theory. From the outside to the inside the segment rings can include the following:

• 1) the key symbols of the major keys,
• 2) the key symbols of the minor keys,
• 3) the representation of the preliminary drawings in the treble clef system,
• 4) the fingering schemes of the major chords on keys (e.g. piano / keyboard),
• 5) the fingering schemes of the minor chords on keys (e.g. piano / keyboard),
• 6) the grip schemes of the major chords as guitar grips,
• 7) the grip schemes of the minor chords as guitar grips,
• 8) the notes of the major series and / or which are confused with enharmones  
• 9) the harmoniously confused notes of the minor series.

Instead of the grip schemes for the mentioned instruments (keyboard instruments or guitar) handle schemes of other instruments can also be provided.

The upper disc is designed so that certain segment rings of the lower disc are not be covered. For this purpose, for example, partial segments of the upper pane are removed or transparently designed ("window"). The top disc is in different sized circle segments, preferably divided into 6 different sized circle segments. These circle segments serve to present certain facts of harmony.

The preferred issues to be presented are:

• A) major / parallel minor key and sign,
• B) major triad,
• C) minor triad,
• D) grip patterns,
• E) Enharmonic confusion and
• F) Cadence.

The segments A) and D) correspond in size to the size of the individual segments of the lower pane, the segments B), C) and E) twice the size of a segment of the lower pane and the segment F) corresponds to three times the size of a segment the lower disc. The segment A) leaves the circular rings 1 ) to 3 ), the segment D) the circular rings 1 ), 2 ) and 4 ) to 7 ), the segment B) the circular rings 1 ) // 1 ) and 2 ), the segment C) the circular rings 1 ) and 2 ) // 2 ), the segment E) the circular rings 1 ) and 8 ) // 2 ) and 9 ) and the segment F) the circular rings 1 ) and 2 ) // 1 ) and 2 ) // 1 ) and 2 ) of the underlying segments of the lower pane become visible. The symbol // symbolizes the dividing line between the segments of the pane below. The circular rings that are visible through the windows of the upper pane are indicated clockwise. The free segment on the upper pane in this embodiment can serve as an information field, for example.

Embodiments of the two disks are preferably shown in FIGS. I and 2 . The hatched fields in FIG. 1 correspond to the windows described above.

Instead of the "Enharmonic Confusion" segment, you can use the lower and the lower the upper pane of the aid according to the invention, which is in each case confused with enharmonics Tones are right next to the "original tones".

According to the above-mentioned facts, the segments of the upper disc can also be named.

Depending on the size of the aid according to the invention, further facts of the ele represent mentary music on the two discs. These include, for example:

• - the scale
• - the pre-drawing of the keys in any other key
• - seventh chords as well as all other chord forms (ninth chords, Undecime chords etc.) and / or the
• - minor cadence.

These facts also result directly from the well-known fifth circle. They can be represented by appropriate assignments, for example by arrow markings and / or windows, or by means of interchangeable "working disks" clear.

Preferred configurations of such "working disks" are shown in FIGS . 3 to 9 Darge. The hatched fields in FIGS. 3 to 9 correspond to the windows described above.

The size of the aid according to the invention depends on the number of the on the disks to be presented. To illustrate, for example, the common most facts

• A) major / parallel minor key and sign,
• B) major triad,
• C) minor triad,
• D) grip patterns,
• E) Enharmonic confusion and
• F) Cadence,

a diameter of about 20 cm has been found to be suitable. The advantage of this size This is also due to the fact that the aid goes well with standard notebooks / books. With larger diameters, as already mentioned, more facts have to be shown. For Use in music lessons in schools, on the blackboard as a teaching tool for teaching powers, in the hands of the students as a training device and for tasks of the elementary har The aid according to the invention can also be taught in the form of an oversize len panel picture can be designed.

Devices can be attached to the panes for easier handling serve to be able to turn the disks better. For example, on both Disc protrusions ("noses") are attached or a holder on the lower disc device and on the upper disc a kind of "gag" with which the upper disc can twist. To make it easier to find the facts presented, the upper one Disc also have engravings. To blind the handling of the invention To enable aids, the disks can be made according to the specifications of the blind writing as well as the blind notation.

Not all mentioned and possible segments have to be shown on the upper pane will. It is also possible to select "working disks" (see above), so that, for example, each  after training of the person using the aid or according to the intended purpose, only be agreed facts can be presented. This avoids unnecessary "ballast" will.

The rotatable attachment of the two disks is preferably designed to be detachable. Hereby For example, it is possible to insert different upper panes depending on the intended use put.

The aid according to the invention can be produced from a wide variety of materials alien. Cardboard, paper, wood or plastics of various types are preferred, such as white plexiglass.

Depending on the material used, the imprint, in particular that of the upper pane, can reinforced by engravings.

The back of the aid according to the invention can carry a description. she can Briefly explain all the facts that are present in the segments of the two discs represents are. You can also describe how it works to explain what it is all about with the respective design of the aid according to the invention can.

The following describes how the aid according to the invention is used:

To show the respective facts, the upper disc is rotated so that the respective window of the situation to be displayed with a segment of the lower pane Cover is brought. In particular, in a preferred embodiment of the Aids according to the invention are shown:

The major key / parallel minor key: the known key in the ent speaking segment window of the upper disc searched and the desired key read. At the same time, the signs can be determined in this segment.

The key patterns for keys / guitar: the corresponding upper segment window of the Segment "Griffbilder" with the desired key to cover. The grip patterns can be read in the lower segment window.

Enharmonic confusion: the upper segment window of the "Enharmo African confusion "with the desired key. The enharmonic confused sound can be read in the lower segment window.

Cadence: the aid according to the invention represents the expanded cadence, that is to say the chords / triads of the simple major cadence (tonic, subdominant and dominant) the chords of the parallel minor keys must also be determined. To do this in the segment "cadence" the subsegment "tonic" with the key designation to cover brought, which should serve as a reference key. About the sub-segments ,, Subdominant  or "Dominant / are the details searched for.

minor triad: each triad is made up of the fundamental, the third (here: minor third) above the root and the fifth above the root together. To represent the The segment window of the "minor triad" segment becomes triad with the desired one Root of the minor triad coincident. The small one is above the fundamental Third, to the right of the root note to read the fifth of the triad. To illustrate Chung this fact, the aid according to the invention in the segment "minor-three figurative aids, for example in such a way that the three tones of the triad are presented in the usual, symbolic form and root, minor third and fifth can be assigned to the symbol of the triad by arrows.

Major triad: the segment window of the segment is used to represent the major triad "Major triad" coincident with the desired root of the major triad. To the right of the root note is the fifth of the triad, including the third of the three read sound. To illustrate this fact, the invention Aids - have figurative aids in the "major triad" segment, for example derge stalt that the three tones of the triad are represented in the usual, symbolic form and the fundamental, third and fifth are assigned to the symbol of the triad by arrows the.
