What is it? What keys would usually employ it?

How do you do it with autoharp?

What are some songs done in that mode?

What mode would it be then, you know-- by the usual mode names?

Would songs using this always be minor or major, or could they be either? Why?

Typical chord progressions?

Any tricks to the harmonies that would work-- would they be within the modal scale, or some other wacko approach?

Any way to recognize these in dots-- would it be a regular key signature then certain dots flatted or sharped?

Anything else related to this, or other common modes found in bluegrass gospel????

I need to know. HERE'S WHY.

Help! And thanks. I promise to use any secrets learned only to bring about world peace! (Peace IRL, not Mudcat peace. I dunno how to make that at all.)
