Question by Fred
In your “Learning 3 Basic Chord-Scales for Jazz Guitar” video and PDF, you show three chord voicings for Dm7, G7, and Cmaj7 chords. I’m confused. I understood that, let’s say, a 7th chord consists of 1-3-5-flat7 = G-B-D-E. So how is it that these G7 chords use notes B-F-D-A? Am I missing something basic here?
I played some jazz guitar (mostly memorization) many years ago, and decided to pick it up again, learning some theory this time around. Thanks. You website is a great teaching tool.
Thanks for you question.
Haha! That’s a good one: in fact, did you notice on the C major 7th voicing I wrote “with the 9th”. I probably forgot to write it down for the G7 chord…
So here’s how the third G7 voicing works : it’s, as you said, the notes B-D-F-A … meaning that they are 3-5-b7-9 of the G root. This is very common in jazz. It’s called adding extensions.
Please refer to “The No Nonsense Guides to Jazz Harmony” for more about extensions, inversions (and more!)

G7 to G9 chords?
Josh, you are right. G7 (dominant)is G-B-D-F. Probably just dazed and confused here in Ohio as I wrestle with music theory. Thanks.

G B D E?

I’m not sure if this was a typo, but if not, maybe you just got mixed up with the chord… G7 is G B D /F/. (In G major, the normal 7 is F#, and the flat 7 is F.
