This site might make it easier to understand, for folks that are typing stuff into BIAB, given the nature of modal scales.

Say you are trying to set up a C Dorian progression in BIAB.

If you type in III if the key is set to C you will get E, not Eb, so it would actually be a III minor is you are trying to build a transposable template. I am experimenting with Eb and C minor as the key and not getting what I want. Still fiddling...

This may drive people mad.

However, if you just want the charts and notes above, this will explain it, and away you go.

Also, remember A Dorian is "A Minor-ish" but not Not A Minor and does yield exactly the same chord progression as the A Dorian Dan referenced in his example.

Look here:

Simply studying the two links for these two examples gives a boatload of info of the simple but profound differences between "pop" and "jazz.

Though the two "minor" modes are similar (A Dorian and A Minor), the 6th chord of the A minor Progression is F, and the Dorian 6th is F# dim.

Huge difference. And therein lies the rub.
