Tomo Fujita Guitar Wisdom

I am confused… 🤔 because the key of G has a F sharp, shouldn’t a G7 chord have an F sharp? I think I am missing something because I see G, B, D, and F as a G7 chord and I don’t know how to think about it.

Kind regards- Marcus

This is a good subject. There’s a lot of material in guitar wisdom about dominant chords. Was looking at BL07. Theres a flat 7 in a dominant 7 chord even though it doesn’t say this. F natural for this one here. One string approach you can tell the sound is different. This would be a natural f for the 7. I need to go back and review this more.

Thanks Kurt, now I can think of it different as a flat seventh. I sure didn’t understand why they flattened the seventh. I think I need to study dominant 7th chords. Like a flat third is a minor chord I guess..?

Thank you Marcus for this question! Thank you Kurt and Jeff for sharing suggestions! You guys are so great!

A little confusing about b7 and minor 7th & dominant 7th! Something similar.

7th chords are:
1) Major 7th = R M3 5 M7 = C E G B = CMaj7
2) Dom 7th = R M3 5 b7 = C E G Bb = C7
3) minor 7th = R b3 5 b7 = C Eb G Bb = C-7

Key of G has F# : G A BC D E F#G ... F# is Major 7th.
You are thinking about G7. I think you mixed up with "Key" and "Chord"
