Let's say I have a Bbmajor scale. The seventh degree would be A. Now, are the triads: A-Cb-Ebb-Gb Since it's the seventh degree that would a Amin7b5 chord right? Whats bothering me is that the Bbmajor scale has an Eb in it. Does this mean that I have to "flatten" it once more or just leave it as it is because it already is flat? Hope you understand my question..
