Common Chord Extensions

It’s very common to play the b7 - 9 - 11 over the bass note, leaving out the 3rd. You end up with a triad a tone below the bass note, often written as G/A (G triad over an A Bass note), which we could also write as G11.

Could you please tell me exactly what notes are in this G/A chord. In a G7 chord the 7th is an F, the 9th is an A and the 11th is a C. I dont get how A could be the base note as it is the 9th and in the middle of this triad. Are you putting the G in between the F and the A of this triad? Looking at the video it looks like that Justin was fingering an A over a GBD triad which would be the 9th over a basic 1-3-5 triad. But that is not leaving out the 3rd.
edit: ok, I just caught what this was in the video, Justin quickly mentions this is an A11 chord. So I’ll leave this question up anyways as someone else might be confused.

Hello @arquebus and welcome to the community.

The G triad contains notes G, B and D.
Meaning G is the b7, B is the 9 and D is the 11.
The bass note is A so that is the 1, the root.

It is an A11 chord but within its structure is a full G major triad so can be referred to as G/A also.

I hope that helps.
Cheers

Hello! Do you guys have examples of chord progressions using the chords that Justing is showing in the video (9, 11 and 13, for Maj, min and dominant)? This could be quite interesting and a good help to learn them in context.
