If you re-read the first few post you may see why I felt the need to express the connection or sameness of Amin and Cmaj scales. People seemed to have the idea that playing C major patterns over a progression of Amin, F, G would be using a different scale/key.
IT'S THE SAME DAMN THING! The chords provide the context that produces the tonal quality of the scale. You can improvise with C major all night long over Aminor chord progressions and WORKS FINE!
When played by themselves C6 and Amin7/C are the SAME.
When played over specific chord progressions, C major and A minor scales produce the SAME sounds.
