Like a progression that is written in the key of G as I-III-IV-bVII-I
Would the bVII be F7 or Fmaj? I know the rest would be Bmin-C-D and of course the I is G
Is the VII flatted alot in gospel music, and how often is the VIIdim used?
I don't think the b7 is used a whole lot in gospel music. Usually gospel musicians will play a variation on the VII.
Israel Houghton uses the flat VII a lot in a lot of his songs. In his case, its usually a bVII major sus chord. It is SO sweet.
Listen to his song "Deeper" and you will notice this. The song is in D and the beginning intro chords go from a Dmaj6 to a Cmaj6 which is the b7 of D major.
Sweet!!!!
