FR2664416A1 - Device for transposing, retranscribing, composing and breaking down scales and chords in music - Google Patents

Abstract

The invention relates to a device making it possible to read and decypher chords and scales in music. It consists of two superimposed discs, of different diameters. The larger diameter disc carries the chromatic notes. The smaller diameter disc carries the essential basic rudiments of theory. It is sufficient to bring the terms "fundamental, tonic, octave" of the lower diameter disc to face a note featuring on the larger diameter disc, by rotational movement, in order to know the qualification and values of all the other notes. The device according to the invention is particularly intended to facilitate learning of the rudiments of theory.

Description

 The present invention relates to a device allowing the retranscription, the retransposition, the composition and / or the decomposition of any agreement or range contained in the music theory.

The device according to the present invention indicates the qualification and the degree of the intervals, as well as the different ranges.

 Currently, decomposing, transposing or knowing the notes that make up a chord or scale requires a good knowledge and practice of music theory.

 The device according to the present invention remedies this by acting as a calculation rule, a table of correspondence of the grades and their qualifications between them. It allows a quick and better understanding of music theory.

On the outside edge of the lower disc (larger diameter) are the musical notes and their Anglo Saxon notation
DO, C; Do *, D 6; D, D; Rée Mi i; Mi, E; Fa, F; Fa *, Sol L.

 Sol, G; Sol #, La b, La, A; La #, Si b; Yes, B.

On the upper disc (of smaller diameter) are written the essential rules of music theory, namely: the qualification of intervals, the degrees of intervals, and the various ranges. The qualifications listed are
Tonic, Fundamental, Octave
Second: minor, Major
Third party: minor, Major
Fourth: fair
Fourth: increased, Fifth: decreased
Fair straight
Augmented fifth, Sixtus: minor, Major
Seventh: minor, Major
The degrees are entered from 7 to 74.

The ranges listed for abbreviation are as follows
M: Major range m: minor range
P: Pentatonic range
C: Chromatic range
T: Ton by Ton range
D: Ton half tone range
The present invention is simple to use by a rotational movement, bringing the "Tonic, Fontamentale, Octave" part of the upper disc facing the first note of the chosen chord, written on the outer edge of the lower disc.

EXAMPLE 1
To decompose the C major, we match "Tonic,
Fontamentale, Octave "from the lower disc with the note Do from the upper disc; and we read
C: Tonic, Fundamental, Octave degree or degree
Do *, Ré l: Second minor
D: Second Major degree or D *, Mi i: Minor third
E: Third Major 3 "'degree or 10
Fa: Fourth just 4fl or 11 'Fat, Sol b: Fourth increased,
Diminished fifth
G: Straight fifth 5 or 12th G #, A: Augmented fifth, minor sixth
A: Sixth major 6 "degree or 13th 'A *, Si 6: Seventh minor
If: Seventh Major 7th degree or 14
By extracting the tonic, the Major third and the right fifth which are the components of the Major chords, i.e. C, E,
G, we have broken down the C major.

EXAMPLE 2
To compose the F Major 7 minor, we bring the Tonic in front of the
Fa and we read
Tonic: Fa; Third Major: The; Fair fifth: Do; Seventh minor: La, Si b
To obtain one or more scales (up to six) from a chord, match the Tonic with the chosen note.

We can then read all the notes corresponding to the scale (see abbreviations above) that we have chosen to execute.

EXAMPLE 3
The Major range of F.

We place the tonic in front of the note F and we read the notes located opposite the abbreviation M, i.e.
F, G, A, Si 6, C, D, E.
