I'll sleep one of these days..
the Dominant 7th Flat 9 Sharp 5 chord.
This is a great chord that you can use immediately.
Currently I use this chord as a passing chord to get me to any minor chord in a progression. This is an altered chord because we've altered the 9 by flatting it and the 5 by sharping it.
Let's look at this chord:
A7b9#5 LH/RH = A/GBbC#F
Chord breakdown wise: in the LH you have the Root, in the RH you have the b7, b9 (Bb), 3, #5 (E# or F)
How would you use this chord?
As I stated before you can use this chord in any progression to pass to a minor chord.
in the Key of F a ii-vi (2-6) progression would be:
LH/RH NUMBER BREAKDOWN Chord Name
G/FABbD 1/7-9-3-5 Gm9
D/FACE 1/3-5-7-9 Dm9
This is the progression that is used during the play over for Byron Cage's I will Bless The Lord of course that song is in Gb for this post's purpose I put us in the key of F but you can transpose these chords to what ever key you'd like.
Here is that same 2-6 progression with the 7b9#5 passing chords in there..
Before I give you that..
A short note here on passing chords: Alot of folks have been asking about passing chords and how to add them to your progressions. One good rule of thumb to use/know is that you can always precede a chord in a progression with a dominant 7th chord that is a 5th away from it. For example...
Orig. Progression: Bbm7 to Fm7
you can add a C7 chord before the F minor chord because it is a 5th away
F major scale = F G A Bb C(5) D E F, the C is a 5th away..
Progression w/ Passing Chord: Bbm7 to C7 to Fm7
Let's try that again:
Orig. Progression: Cm7 to Gm7
using the rule that I gave you what would be the passing chord to add between the Cm7 and Gm7??? D7
G major scale = G A B C D(5) E F# G, the D is a 5th away..
Progression w/ Passing Chord: Cm7 to D7 to Gm7
We're going to apply this same Passing Chord rule to the 2-6 progression in the key of F but instead of just adding a regular dominant 7th chord we're going to add the dominant 7th b9 #5 chord
For reference, original progression is going: Gm9 to Dm9
2-6 Progression w/ Passing Chords:
LH/RH NUMBER BREAKDOWN Chord Name
G/FABbD 1/7-9-3-5 Gm9
A/GBbC#F 1/7-b9-3-#5 A7b9#5 <- Passing Chord
D/FACE 1/3-5-7-9 Dm9
D/F#BbCEb 1/3-#5-7-b9 D7b9#5 <- Passing Chord
Do you understand why we added those passing chord?
Why did we play the A7b9#5 before the Dm9?
Why did we play the D7b9#5 before the Gm9?
If you can answer those questions you are well on your way to learning how to add passing chords to your progressions.
Here is the 7b9#5 chord in every key around the circle of 4th/5th...
C7b9#5 C/BbDbEAb
F7b9#5 F/ADbEbGb
Bb7b9#5 Bb/AbBDF#
Eb7b9#5 Eb/GBC#E
Ab7b9#5 Ab/GbACE
Db7b9#5 Db/FABD
Gb7b9#5 Gb/EGBbD
B7b9#5 B/ACEbG
E7b9#5 E/AbCDF
A7b9#5 A/GBbC#F
D7b9#5 D/F#BbCEb

Another tool to add to your toolbelt!
