Making a "i-VII" bassline?

[owensea777]

the G major scale is G, A, B, C, D, E, F#.
If I wanted to make a i-VII bassline, would I use G minor and F# as roots?

What style of music?

[owensea777]

Reggae. Why does it matter, if i can ask? Maybe I meant I-VII (blame the internet)...

Basically what I'm asking is, when a progression contains a lowercased letter, like an i, what should I use for that chord?

Generally lower case means minor and upper case means major.

^That's the kinda nswer I was looking for, but for Jazzin:
In the key of G, i-VII progression, reggae music

Thanks

Also what kind of minor scale would I (generally) use? natural...harmonic?

[Jazzin']

I'm guessing it would be Gminor and FMajor. If using modes from the Major scale, then it would either be G Aeolian and F Mixolydian or G Dorian and F Ionian. It would be F and not F# since the 7th in the minor scale is 2 semi-tones below the root note.

Huh? If it is in G minor, why do you start my explaining the G major scale? If you use G minor harmonic scale, the roots for the chords would be G and F#. However, the G harm. scale wouldn't fit both chords (G minor and F# major).

I agree with Jazzin' that the i - VII progression probably means G minor and F major. My first choice of scale would then be G dorian for both chords. (The other scales Jazzin' mentioned would probably fit too).

Becasue I don't really know what I'm talking about

for Jazzin's post:
I (think) I understand why you reccomended Aeolian for G minor, because it refered to as the minor key (well that's what a website says anyways). Why exactly did you suggest F Mixolydian, though, instead of F Ionian?
The other suggestion was G Dorian and F Ionian. Why G Dorian here instead of G Aeolian?

I'm guessing because that's what sounds good. Is there any chart or rule about which modes go together?

Many Thanks.

Yup. Play the notes in the G Aeolian scale (which is the basic minor scale).

G A Bb C D Eb F G

Now, if you want to play in that scale, but starting from F, your scale would go:

F G A Bb C D Eb F

Play it and you'll notice that it's not a standard (Ionian) major scale. The 7th note is flat (Eb instead of E), and this scale (flat 7th major) is referred to as Mixolydian.

Basically, if you played an Ionian F scale, your 7th note would sound out of the scale. The same thing with Dorian and Ionian. In this case the Dorian goes:

G A Bb C D E F G

Start that scale on F:

F G A Bb C D E F

And that is your standard (Ionian) major scale.

Read up on modes to figure it out in more depth.

This whole thread scares me.
Are you guys talking about a minor-seventh chord?
Or a I chord, to VII chord progression?

That was me about a month ago (maybe you aren't quite as bad off as I was, though). Thanks to a couple books and Talkbass, I am starting to get this whole theory thing, if only a small part of it. Thanks for the replies everyone.
Lorenzini, do some googling on scales and modes and start threads on TB for some help, if you haven't already. But yea I was asking about a i-VII progression in the key of G minor.
