What key sig?

[RideTheCrash]

I don't know enough theory to figure this out, though I did some searching with no luck. What key signature would this chord pattern be: C, E, Bb, G?

[Purge]

Well, it could be G with a flatted 3rd. Or it could be F. Or (since you haven't mentioned which chords are major or minor) it could be just atonal.

[RideTheCrash]

They are all major, except E, which is minor.

G with a flatted 3rd.

Or...C with a flatted 7th.

[RideTheCrash]

Okay, say you wanted to play a scale over that, what would it be? I assume these flatted parts tacked onto the key change it from just being a G or C scale.

Makes more sense as C with a flatted seventh, since that's a lot more common than a flatted third, and altering the seventh doesn't alter the whole tonality of the scale, like the third does.

[Purge]

The easiest option is to go with your basic E minor pentatonic scales. When that Bb hits, you can "blues it up" by adding in those Bb notes to the pentatonics.

Another option is to play in G, as above. (E minor, G...same thing for all intents and purposes). Then when the Bb is played, switch to a Bb major scale for kind of a funky tonal shift before going back to G.

[Purge]

Good point to Corban. With that approach, you could pretty much play in C and it shouldn't sound too weird. Maybe alternate between C major and C mixolydian?

Thanks guys.

Shit, that is actually wrong. The prog is actually C, Em, Bb and Am. My bad.

That'd be the key of F, wouldn't it?

F Gm Am Bb C Dm Edim F


Edit: well, Em wouldn't work because of the Bb...
I'm just starting to learn the theory myself, but I'd throw the key of F at it and maybe fake the Em / Edim. I'm sure the others will have some better answers.

The C major/C mixolydian thing will still work for this.
