C7#5b9 / Bbm7b5 / Gb9 / Dbm6

The recent Guitar Chord a Day series 12 Dominant 7th Chords, introduced 12 useful dominant 7th guitar inversions.

Today's guitar chord of the day is actually four chords in one:

• C7#5b9
• Bbm7b5
• Gb9
• Dbm6

 Dominant 7th chords are easy to modify to create other chords:

• Lower the 3rd one fret to make a minor7 chord
• Raise the b7 one fret to make a major7 chord
• Raise the root two frets to make a 9th chord

Thinking of our guitar chord as a C7#5b9 - this could be created by taking this dominant 7th chord and raising the root and the 5th by one fret to create a 7#5b9 chord.

Thinking of our guitar chord as a Bbm7b5 - this could be created by taking this dominant 7th chord and lowering the 3rd and the 5th by one fret to create a m7b5 chord.

Thinking of our guitar chord as a Gb9 - this could be created by taking this dominant 7th chord and raising the root note by two frets to create a 9th chord.

Thinking of our guitar chord as a Dbm6 - this could be created by taking this dominant 7th chord and lowering the 3rd and the 7th by one fret to create a m6 chord.

G minor7 b5

Today's Guitar Chord of the Day is Gm7b5. We played an alternative inversion of a m7b5 chord a few days ago.
This inversion has it's root note on the guitar's B string (root notes are shown as black boxes rather than circles in the chord diagrams. Have a look at the introductory post for more info on how to read chord diagrams).
Minor7b5 chords use these scale degrees: 1, b3, b5, b7
Gm7b5 uses these notes: G, Bb, Db, F
Our inversion uses the notes in this order:     F, Bb, Db, G

As mentioned in the previous m7b5 post, m7b5 chords are four chords for the price of one:

Gm7b5 can also be considered as Eb9, Bb minor 6, A7#5b9. Here's why:

Gm7b5    = G, Bb, Db, F
Eb9         = Eb, G, Bb, Db, F
Bb minor 6 = Bb, Db, F, G
A7#5b9 = A, C# (Db), E# (F), G, Bb

Tomorrow starts the first of a series of themed weeks for Guitar Chord Of The Day.  
We'll be looking at guitar chords and inversions made popular by specific artists, used in different genres or based on another common theme. Starting tomorrow we've a week of Jimi Hendrix. Hendrix was famous for his soloing, use of effects and feedback but often his rhythm work is overlooked.

Tune in tomorrow for the start of a mini-series on the chords of Jimi Hendrix at Guitar Chord Of The Day.

D minor7 b5

Today's guitar chord is D minor7b5. It is a moveable chord with it's root note on the A string. Dm7b5 is also known as D half diminished.

Four Chords For The Price of One
m7b5 chords can also be considered as different inversions of other chords, Dm7b5 can also be considered as Bb9, F minor 6, E7#5b9. Here's why:

Dm7b5    = D F, Ab, C
Bb9         = Bb, D, F, Ab, C
F minor 6 = F, Ab, C, D
E7#5b9 = E, G# (Ab), B# (C), D, F

As you can see these chords contain the notes of the Dm7b5 chord, so you can also play this inversion in place of these chords too.

Minor7b5 chords use these scale degrees: 1, b3, b5, b7

Our inversion uses the notes in this order:     D, Ab, C, F
