If I wanted to "translate" this progression into a solo...

[Shelby21]

Got hit with some inspiration late last night around 3 for some easy lyrics, have a verse and chorus. Then I have a simple, yet sweet chord progression

/Dsus4 D Dsus2 D/ not original but it works with my lyrics so Im going with it

Anyway I wanna translate this progression into a Solo I understand its hard because you can't hear how it sound, but maybe someone can help out with a scale pattern. I want the song in key of G, Im using G and C in the bridge to distant from the original progression.
Thanks to all in advance any other questions please leave them.
Btw this is what I have so far in my song:
(for some reason when I post it squeezes all the chords together thats not how they are to lyrics but its just to give others an idea)

Thought I Had It All Figured Out
Key of G
Intro: /Dsus4 D Dsus2 D/ /Dsus4 D Dsus2 D/

Dsus4 D Dsus2
I got my cards laid out across
Dsus4 D Dsus2
My last hands been dealt it's all a toss
G C G
I thought life was so good to me
C G Dsus4
There was no chance I could let it all be


Dsus4 D Dsus2 D
Thought I had it all figured out
Dsus4 D Dsus2 D
Thought I had it all figured out
G C
Life's gotta change there is no doubt
Dsus4 D Dsus2 D
I thought I had it all figured out

there' a couple of ways you could approach this...

my gut reaction was to play in D major over the Dsus/D business, and switch to G for the chorus...

but you could in theory play in G over the whole thing, which, despite my raging against looking into modes, is like thinking D mixolydian over the D part. it's gonna depend on whether or not you like the sound of the C natural over those chords--i kinda did...

not sure of the overall vibe you want, but i did sort of a slow strum, roostsy, "midnight rider" vibe type thing when i tested it out, so i even used some D blues scale licks over the return to the D after the G-C part... which sounded cool--i just made sure to not hang on the minor third and resolve to a strong chord tone, like the major third over the D's (the F#)...

Yea I think I would wanna go with the D major because the background progression was gonna be the Dsus4 D Dsus2 D pattern, not long though...

You've got a pretty floaty chord progression, where there is some change, but little tension and resolution. You can work with that in your solo. This about this:

D = D F# A
D sus 4 = D G A
D sus 2 = D E A
G = G B D
C = C E B

Looking at individual notes and how they related to the chords:

G is consonant with everything except D, when it clashes with F#
A is consonant with everything (a major second against G and B isn't bad)
B is consonant with everything except C, when it clashes with the note C
C is consonant with everything except G, when it clashes with the note B
D is consonant with everything (a major second against C and E isn't bad)
E is consonant with everything (a major second against D and C isn't bad)
F# is consonant only with D, not with C and G

This implies that you could create minimalist repeated figures like the Edge, Eno, Fripp and seconds and ninths like Andy Summers. You could try building repeated note patterns, like D D D D | D E E E | C D D E | E E D D | C C A A | A D D D |, which would sound better as 16ths or triplets. The chords don't suggest scale-like runs to me, since there is not much tension and resolution implied.

I would be tempted to use a G major scale and try to stay away from the 7th degree unless my ear really wanted me to be there. Like Larry pointed out, you have the intervals of the G major scale there. It would be a little boring to start out, but once you frame the melody you can add whatever you want to it.
