Yeah, I would think of that as the C shape/form, from your OP.

Wasn't sure which of the chords you were talking about for the A shape.

Yeah.  Tritones abound.

Yeah the A shape is the shape I just posted and have tried to show a simple way.
The C shape is the 13 with the root on top I think.
It was the Larry and Robben chord shape

e X
B 1
G 2
D 2
A 1
E X
I think this is the C form of this no root chord

F13 formula:

1   3   5   b7   9   (11)   13
    OR
F   A   C   Eb   G  (Bb)    D

C13 formula:

1   3   5   b7   9   (11)   13
    OR
C   E   G   Bb  D    (F)    A

The most important degrees in this chord are 1 3 13 b7, which are the notes in your chord. So, yes that is a C13 chord, But, there is a root note in this chord, it is just inverted; it is the 2nd string.
Hope this helped.

I have a question.

I've checked the notes of this chord but i am not seeing where the 13th is im getting 14th chord, am i getting something wrong here:



Lets say its in B. So i got:

B - Eb - A - Db - G#
1 -  3  - 7 - 9  - 14

Why is this not a 14th chord ? Please explain, this has confused me.

I'm curious if it should be Gb for 13th chord?

C E Bb D A
1 3 b7 9 13

The 13 is the same note name as the 6th.

Not sure why B is easier but
B D# A C# G# sake numbers... So G# is the 6th degree of the B major scale so its a 13 in the next octave.

B C# D# E F# G# A# B C# D# E F# G# A#....

By the way the key signature of B has 5 sharps...

Ah i see my mistake.

I was thinking 8 + 6 = 14th.  When really i should also count the next octave root as part of the 6 notes.

Thanks for clarifying.

How common is it for blues players to mix up 7ths, 9ths, and/or 13ths from verse to verse or even within the same verse?  I've been fiddling around with use a 13th chord on the I and 9ths on the IV & V or vice versa or playing 9ths and switching to 13th for a verse or two.  I think it sounds good.

@ mbockbra

Those substitutions are fine ... context is a factor ... if it sounds good it is good.
