C major scale | Modes in terms of tetrachords
Find previous blog posts covering tetrachords in part 1 and part 2 of this tutorial.
C Ionian Scale
The C Ionian Scale is a combination of the Cmaj tetrachord and the Gmaj tetrachord separated by a major second (2).
G Mixolydian Scale
The G Mixolydian Scale is a combination of the Gmaj tetrachord and the Dmin tetrachord separated by a major second (2). The upper Gmaj tetrachord of the C ionian scale becomes the lower tetrachord of the G mixolydian scale.
D Dorian Scale
The D Dorian Scale is a combination of the Dmin tetrachord and the Amin tetrachord separated by a major second (2). The upper Dmin tetrachord of the G mixolydian scale becomes the lower tetrachord of the D dorian scale.
A Aeolian Scale
The A Aeolian Scale is a combination of the Amin tetrachord and the E phrygian tetrachord separated by a major second (2). The upper Amin tetrachord of the D dorian scale becomes the lower tetrachord of the A aeolian scale.
E Phrygian Scale
The E Phrygian Scale is a combination of the E phrygian tetrachord and the B phrygian tetrachord separated by a major second (2). The upper E phrygian tetrachord of the A aeolian scale becomes the lower tetrachord of the E phrygian scale.
B Locrian Scale
The B Locrian Scale is a combination of the B phrygian tetrachord and the F whole-tone tetrachord separated by a minor second (b2). The upper B phrygian tetrachord of the E phrygian scale becomes the lower tetrachord of the B locrian scale.
F Lydian Scale
The F Lydian Scale is a combination of the F whole-tone tetrachord and the Cmaj tetrachord separated by a minor second (b2). The upper F whole-tone tetrachord of the B locrian scale becomes the lower tetrachord of the F lydian scale.
C Ionian Scale
The C Ionian Scale is a combination of the Cmaj tetrachord and the Gmaj tetrachord separated by a major second (2). The upper Cmaj tetrachord of the F lydian scale becomes the lower tetrachord of the C ionian scale.
And so the circle is complete.
