Utilities Circle Of Fifths
Circle of Fifths
On the circle of fifths you can find the chromatic scale in an altered note sequence. The interval between two neighbouring notes is called pure fifth.
Application #1, Parallel Major and Minor Scales
The Natural Minor scale and the Major scale are Parallel scales and contain the same notes and key signatures. The Natural Minor scale is always a minor third lower than the Parallel Major scale. Here are the Parallel Minor and Major scales with their key signatures:
The parallel key of each major key is built by playing the same notes but instead starting with the sixth note of the major scale. That leads to the following rule.
The VI degree of a Major scale is the root tone of the Parallel Minor scale. The III degree of the Minor scale is the root tone of the Parallel Major scale.
Example:
Parallel Major and Minor Pentatonic
The same rule can be applied for the Parallel Pentatonic scales, too.
The VI degree of the Major Pentatonic is the root note of the Parallel Minor Pentatonic. The III degree of the Minor Pentatonic is the root note of the Parallel Major Pentatonic.
Example:
Application #2, Key Signatures
Also the key signatures follow the law of the circle of fifths, then between neighbouring key signatures the interval is a fifth, too.
F# – Fifth – C# – Fifth – G# – Fifth etc.
F#, C#, G#, D#, A#, E#, B#
Kein Wunder sind bei so vielen Vorzeichen die altbewährten Eselsbrücken immer noch von Nutzen.
Doch aufgepasst! Im ScaleTwister wird die internationale Notenbezeichnung angewendet.
H ist im Scale Twister B
B ist im Scale Twister Bb
Für #-Vorzeichen gilt:
Geh Du Alter Esel Hole Fische.
Für b-Vorzeichen gilt:
Frische Brötchen Essen Alte Damen Gern.OderFritz Brachte Esther Astern Des Gesangvereins.
Progression
Cadere, lat. = falling — A progression is a sequence of chords from scale notes (diatonic). The progression helps to build up suspense (Dominant) and the dissolution to the root chord (Tonic). Here is a table of the chord degrees of the Major scale.
The chord degrees can be assigned into 3 groups
Dur-Kadenz
Die Dur-Grundkadenz und damit die am häufigsten verwendete Dur-Kadenz hat folgende Struktur:
While the minor progression of the Harmonic scale with the major triad as dominant is the most important one, the progression of the Melodic Minor scale is rarely used.
