Circle of Fifths

Scale Construction

Definition: The Circle of Fifths is a visual representation of the relationships among the 12 tones of the chromatic scale, organized by perfect fifths.
Order of Notes: Starting from C, the notes progress in perfect fifths:
- C, G, D, A, E, B, F♯, C♭, F, B♭, E♭, A♭, D♭.
Major Scales: Each note corresponds to a major scale; for example:
- C Major: C-D-E-F-G-A-B
- G Major: G-A-B-C-D-E-F♯
Minor Scales: Each major scale has a relative minor scale, found a minor third below:
- E minor is the relative minor of G Major.

Key Signatures

Definition: Key signatures indicate the number of sharps or flats in a scale and are associated with their respective major and minor keys.
Sharps:
- Each step clockwise on the Circle adds one sharp:
  - C Major (no sharps) → G Major (1 sharp) → D Major (2 sharps) → etc.
Flats:
- Each step counterclockwise adds one flat:
  - C Major (no flats) → F Major (1 flat) → B♭ Major (2 flats) → etc.
Order:
- Sharps: F♯, C♯, G♯, D♯, A♯, E♯, B♯
- Flats: B♭, E♭, A♭, D♭, G♭, C♭, F♭
Determining Key Signatures:
- Count the number of sharps/flats in the key signature to identify the key.

Musical Intervals

Definition: Intervals are the distance in pitch between two notes and are fundamental in music theory.
Fifth Interval: Each step around the Circle represents a perfect fifth interval.
Types of Intervals:
- Perfect: Unison, Fourth, Fifth, Octave.
- Major: Seconds, Thirds, Sixths.
- Minor: Seconds, Thirds, Sixths.
Interval Identification:
- Listening and recognizing the sound of different intervals helps in understanding melodic relationships.
Relationship with the Circle:
- Moving clockwise corresponds to ascending fifths; moving counterclockwise corresponds to descending fifths or ascending fourths.

Circle of Fifths

Scale Construction

The Circle of Fifths visually represents the 12 tones of the chromatic scale arranged by perfect fifths.
Starting from C, the notes progress in perfect fifths: C, G, D, A, E, B, F♯, C♭, F, B♭, E♭, A♭, D♭.
Each note corresponds to a major scale, with examples like C Major: C-D-E-F-G-A-B and G Major: G-A-B-C-D-E-F♯.
Each major scale has a relative minor, located a minor third below, such as E minor being the relative minor of G Major.

Key Signatures

Key signatures show the number of sharps or flats in a scale, linking to their respective major and minor keys.
In the Circle, moving clockwise adds sharps: C Major (no sharps) → G Major (1 sharp) → D Major (2 sharps) and so on.
Conversely, moving counterclockwise adds flats: C Major (no flats) → F Major (1 flat) → B♭ Major (2 flats), etc.
The order of sharps includes F♯, C♯, G♯, D♯, A♯, E♯, B♯; for flats, it includes B♭, E♭, A♭, D♭, G♭, C♭, F♭.
To determine key signatures, count the sharps or flats present to identify the corresponding key.

Musical Intervals

Intervals measure the distance between pitches and are essential in music theory.
Each step around the Circle represents a perfect fifth interval.
Types of intervals include perfect (Unison, Fourth, Fifth, Octave), major (Seconds, Thirds, Sixths), and minor (Seconds, Thirds, Sixths).
Recognizing the sound of different intervals through listening aids in understanding melodic relationships.
Moving clockwise on the Circle corresponds to ascending fifths, while moving counterclockwise indicates descending fifths or ascending fourths.
