G 11th and G13th

[dwest2419]

What notes are optional when playing bigger chords like G11th and a G13th?

[berbie]

For a 13th, I play a b7-3-6 with my right hand and a 1 with my left. Example, C13= C/Bb-E-A. F13= F/Eb-A-D.

Anything after the 7th chord, all you really need is the root, 3rd, 7th, and whatever extension note.

maj 11th: 1-3-7-11
dom 11th: 1-3-b7-11
min 11th: 1-b3-b7-11

maj 13th: 1-3-7-13
dom 13th: 1-3-b7-13
min 13th: 1-b3-b7-13

Talking keyboards, a dominant 11th is easy.  Simply play the bass note of the chord desired, usually with the left hand, and a Major triad of the note one step below.  Example:  C11=  C/Bb-D-F or D-F-Bb or F-Bb-D.   You have the 1-b7-2(9)-4(11).

You have to note on that dom11 that the 3rd is missing. So, it's not a true dom11, but like you said it's an easy way to form the chord and get the same effect.

To be honest, T, I don't know why I left out the 3rd. I'll put it back in there and see how it sounds.

Review reveals that it is not unusual to leave the third and fifth out.(dominant 11th)

Anything after the 7th chord, all you really need is the root, 3rd, 7th, and whatever extension note.

maj 11th: 1-3-7-11
dom 11th: 1-3-b7-11
min 11th: 1-b3-b7-11

maj 13th: 1-3-7-13
dom 13th: 1-3-b7-13
min 13th: 1-b3-b7-13

I agree with T-Block   here.    I typically leave in the 3  to distinguish between major/minor,   and I use the 7 or b7  to distinguish  between major7 and Dominant7.   Also for me whenever I hear or see 13, in my head I think 6.   whenever I hear  or see 11, in my head I think 4  ( and vice versa).  So for me its easy to substitute  a 13 chord for an add 6 chord,   and an 11 chord for an  add 4 chord ( and vice versa).
