Jazz Guitar Chord Chart #2

Altered Dominants and Diminished 7th

Welcome to this premium online jazz guitar chord chart. I'm sure you'll find every "chord shape" you can possibly need on this very page! If not, please let me know by posting a question or a comment (at the bottom of this page) and I'll get back to you shortly...

Please note that this chart is only for chords in root position (meaning that the tonic is the lowest note). We'll deal with inversion in another jazz guitar chord chart shortly.

So...

What chords do you want to learn ?

All in "C" ? What the ... ?!

Yes, I know. All the chords on this page are movable chord shapes.

I have indicated the "C" (root of chord) in red color. As long as you know what the bass note is, you will be able to use any chord shape in 12 keys!

For example : a basic C major 7th shape at the third fret becomes a Fmaj7 when played at the 8th fret...

This is called transposition. It's easy on the guitar... (at least when you know the notes on the biggest strings of the instrument.)

How to identify diminished 7th chords... often printed on charts as :

• dim7
• diminished(b5)
• with this symbol :

circle (or degree sign), meaning "fully-diminished")

Since diminished chords are symmetrical structure (construction = 3 stacked minor triads) all the notes in the voicing can considered to be the root. It's means that Cdim7 = Ebdim7 = Gbdim7 = Adim7.

Altered Dominants

How to identify altered dominants : they are "plain 7th" chords with one or more sharp or flat notes in between parenthesis.

For instance : Eb7 (#9) or F#9 (b5) or Bb9 (#11)...

There is often more than one alteration in between brackets! It looks like this : D13 (#5, b9) or even C13 (b5 #9)

Why altering dominants chords? Here's a discussion on the role played by dominant chords in music...

Dom 7th (#11) and Dom 7th (b5)

Please understand that the #11 and b5 alterations are enharmonic. It means that it's the same note literally. Here's why :

Dom 7th (#9)

Please note that it's more convenient NOT to play the root in the C7(#9) shape on the left. I indicated it anyways with a red dot, but it's optional.

Dom 7th (#5) and Dom 7th (b13)

Please understand that the #5 and b13 alterations are enharmonic. It means that it's the same note literally. Here's why :

Dom 7th (b9, b13)

Dom 7th (b9, b5)

Please note that it's more convenient NOT to play the root in the C7(b5 b9) shape on the left. I indicated it anyways with a red dot, but it's optional.

Dom 7th (b5, #9)

Please note that it's more convenient NOT to play the root in the C7(b5 #9) shape on the left. I indicated it anyways with a red dot, but it's optional.

Dom 7th (#5, b9)

Please note that it's more convenient NOT to play the root in the C7(#5 b9) shape on the left. I indicated it anyways with a red dot, but it's optional.

Dom 7th (#5, #9)

Please note that it's more convenient NOT to play the root in the C7(#5 #9) shape on the left. I indicated it anyways with a red dot, but it's optional.
