Also called Lydian b3 b7 Mode

C Harmonic Minor starting on F =  F,  G, Ab,  B, C, D, Eb, F, G,  Ab,    B,  C,   D,  Eb,    F
F Dorian #4 scale numbers         = 1,  2, b3,  #4, 5, 6, b7, 8, 9, b10, #11, 12, 13, b14, 15
Notice that 2/9, #4/#11, 6/13 are the same notes.  
Get use to them being referred to both ways. This one number system applies to all keys!

Now lets take every other note in a group of three, four, five, six, and seven notes.

3 notes   = F, Ab, C                   = F minor                                                  (Fm)
4 notes   = F, Ab, C, Eb              = F minor seventh                                     (Fm7)
5 notes   = F, Ab, C, Eb, G         = F minor ninth                                         (Fm9)
6 notes   = F, Ab, C, Eb, G, B     = F minor ninth/sharp eleventh                  (Fm9/#11)                       
7 notes   = F, Ab, C, Eb, G, B, D = F minor ninth/sharp eleventh/thirteenth (Fm9/#11/13)

Other common minor chords:
(small m means minor - also / means to add those 
additional notes to the original 3 note chord or triad)

Fm/9                                       = F, Ab, C, G
Fm/#11                                    = F, Ab, C, B
Fm7/#11                                  = F, Ab, C, Eb, B
Fm7/13                                    = F, Ab, C, Eb, D
Fm7/9/13                                = F, Ab, C, Eb, G, D
Fm7/#11/13                             = F, Ab, C, Eb, B, D

Fm/6                                       = F, Ab, C, D
Fm/6/9                                   = F, Ab, C, D, G
Fm/6/#11                               = F, Ab, C, D, B
Fm/6/9/#11                            = F, Ab, C, D, G


So here is your assignment that you will do with all keys using the Dorian #4 Mode.
Dorian #4 chord progression key of C harmonic minor:

Original progression  - Fm //// Bo //// Cm //// Ab ////     (i, ivo, v, III)  
Now with sub chords  - Fm/6/9 //// Bo7 //// Cm maj7 //// Ab maj 7//// (i/6/9, ivo7, v maj 7, III7)  
 
You can use any of the 4 note chords to replace the 3 note chords.
You can use any of the F minor chords in this lesson to sub for the i of the F Dorian #4 mode.
I will expand on this in greater detail later but for now go back to all the Dorian #4 chord progressions previously given (Harmonic Minor Modes - Dorian #4 - Mode 4) and sub the 4 note chords for the 3 note chords and sub the i chord with the new i chords from this lesson.


Also take these chord formulas and a note name chart and start to create these chords in all possible octaves and positions. When creating chords on the guitar the root,third, fifth or seventh are often omitted because of just having six strings. 
You can use all notes when multi-tracking.


Now transpose these to each position (register) of your instrument, then to all 15 keys.
