What's the difference between G and G7 chords on guitar?

Question

I'm a beginner guitarist, but have been playing piano, drums and singing for years. I understand that in guitar, Gm = G minor, but what does the G7 chord stand for? like Gm is the G chord in minor, but what is the G7 chord in relation to just the regular G chord?

and also, does anyone have any songwriting tips? i have the vocal notes down (the rhythms are slowly coming along), but i just am having trouble finding chords and chord changes that fit with my song (there aren't any key changes in the song, but i dont want to be playing the same guitar chord throughout the whole song!)

Answer 1

you add the flatted seventh note of the G scale in this case it is "F"

Major chords = root, 3rd, 5th
Minor chords = root, flatted third, 5th
Seventh chords = root, 3rd, 5th, and flatted 7th

Seventh chords are "transitionary" they announce something is going to change. Create tension. pull for a "resolve"

Answer 2

Actually you've got it backwards. Blues usually always follows form. A standard 12 bar blues is usually 4 lines of 3 bars. the first line of the verse is usually repeated over the first 6 bars, followed by another line over 3 bars and a final bar of the verse over the last 3 bars. There are several variations of blues as well, but the 12 bar is the most known form. Jazz can follow form if that's the way it's written or if that's the way the musician decides to interpret it, and jazz allows for free improvisation. Any improvisation in blues, still follows the basic musical form. Jazz can and does also reflect economic and social situations the same as blues and any other music...ever hear the song Strange Fruit by Billie Holiday? It's about the lynching of black men in the south...the men being sung about were hardly middle class. Blues is the father of jazz chronologically speaking

Answer 3

G7 Guitar

Answer 4

If you're playing an open G with your middle finger on the low E string, 3rd fret, index finger on the A string, second fret, and ring finger on the high E string, 3rd fret, you need to reconfigure. Try ring finger on the low E string, 3rd fret, middle finger on the A string, second fret, and index finger on the high E string, first fret. Thus the flattened 8 (high G) becomes a 7 (F) of the G scale.
