No, its not single note scales im talking about. Ugh, im not rele sure what to call them but theres the C major scale and for chord progressions you can take out like the I-III-V-I. But the preblem is I can only remember the Cmaj. scale. Like I searched it and some one was using the Am scale instead so I in the Am scale chord progression was Am instead of C. If that makes any sense... but I wanna know as many of the scales for use in chord progressions as possible.
