Minor Modes Part 3
the Locrian Mode scale (7th mode of the Major Scale) has a formula of 1, b2, b3, 4, b5, b6, b7 showing that to get the Locrian mode from the minor scale we need to lower the 2nd note a half step as well as the 5th. Lets take G minor who's notes are G, A, Bb, C, D, Eb, F
going by the above formula for Locrian all we have to do to G minor is lower the 2nd to Ab and the 5th to Db so G Locrian is G, Ab, Bb, C, Db, Eb, F. You could also think of this as G Phrygian with a flatted fifth
The Chord scale for this mode is as follows
G Locrian triad chord scale is as follows
1 dim, b 2 maj, b3 min, 4 min, b 5 maj, b6 maj, and b7 min
and the 7th chord scale is as follows
1 min7b5, b2 maj7, b3 min7, 4 min7,b 5 maj7, b6 dom7, and b7 min7
I cannot recall any song I can think of that has been written around this mode but I still need to give this mode some lip service. This mode is best utilized over a min7b5 chord
To get a feel for this play a G minor7th b5 chord and play locrian on top. You can also play a G minor but don?t sit on the flat 5. instead use it as a passing tone to the 4th if you wind up stuck on it for too long it will clash with the 5th in the chord. Unless what you?re looking for is minor 2nd harmony.
The Harmonic minor scale has a scale formula of 1, 2, b3, 4, 5, b6, 7 showing it has an alteration of the 7th note of the scale showing that is raised a half step, as compared to the natural minor scale.
Lets take G minor who's notes are G, A, Bb, C, D, Eb, F
going by the above formula for G harmonic minor all we have to do to G minor is raise the 7th degree to F# so G harmonic minor is G, A, Bb, C, D, Eb, F#
You may be wondering why there are sharps and flats in the same scale. This is to keep with the 7 notes to a scale in order to correctly write the note it must be written as F# and not Gb and also F# is the 7th note of G Major
The G Harmonic Minor triad chord scale has the following chord formula
1 min, 2 dim, b3 aug, 4 min, 5 maj, b6 maj, and 7 dim
The 7th chord scale for G Harmonic Minor is
1 min/maj7, 2 min7b5, b3 aug7, 4 min7, 5 dom7, b6 maj7, and 7 min7b5
It is called harmonic minor because back in the classical period people wanted more pull back to the root since in the traditional minor scale the 5 chord is minor and lacks the pull of its major counterpart they raised the 7th note of the minor scale so that it would make the 5 chord maj so it has a lot more pull back to the root. So it was changed for harmonic reasons.
To get a feel for this play a G minor chord and play harmonic minor on top and listen for the added half step resolution of the raised 7th. You can also play a G min7 but don?t sit on the raised 7th instead use it as a passing tone to the root.
A couple of chord progressions are as follows
1) G min, C min, F# Dim, G min
2) G min, Bb maj, Eb maj, D maj
next time I will be discussing a mode of the harmonic minor scale mode 5 (otherwise known as Phrygian dominant) and discuss the melodic minor scale. Have fun and pm me for any questions.
