Matching a scale to a set of chords

[dcgsmix]

Hello

if i have some chords, lets says, C G A# F, how do i find a matching scale?

i'm just learning scales, and i do not get what are the modes for... thanks for any help...

Could you be a bit more specific? Like are the chords major or minor or what? If you don't know, you can post the fingering for the chords, and I'll tell you what they are, and what mode correlates to the progression.

Examples:
Em = 0,2,2,0,0,0
C = x,3,2,0,1,0

Well, without knowing whether the chords are major or minor, try C mixolydian or C minor.

If all of the chords are major chords, than I'll rename that A# as a Bb... I've played a song similar to this (it went G, G, F, F, C, Bb, C, Bb, G) and through some trial and error rather than sitting down and thinking about it, I found that the G Minor Pentatonic or G Blues scales sound great over the progression.
Think about it, the G Blues scale contains G, Bb, C, Db, D, and F. Analyzing these notes in relation to chords will show why it sounds so good.

Notes relative to the chords:
C Chord = C, E, G
G Chord = G, B, D
Bb Chord = Bb, D, F
F Chord = F, A, C

The G Blues scale adds the b7 and b9 to the C chord. It adds the b3, b5, and b7 to the G chord. It adds the b3 and b6 to the Bb chord. Finally, it adds the #5 to the F chord. Playing a minor scale over a major chord implies a blues/rock sound (one plays an E Minor pentatonic scale over an E7 chord quite frequently in blues progressions).
