Okay, I took it to the keyboard. It works a lot better in a natural minor key than a major key, b7 b3 b6 2 5 4. I put a b5 grace note on the 4. It doesn't really appeal to me, though. Maybe it would work as a riff somewhere? Oh, just tried it Dorian, with a natural 6. Sounds a little better. Mixolydian is a little weird, with a natural 3, but if you were playing (or singing) first the Dorian and then the Mixo, it would give you emphasis and movement... if you want a tritone (Bb to E) in your melody. Maybe if you were emphasizing chaos or angst in your lyrics... I dunno.

It seems more like a sight-singing exercise than any kind of melody I'd really put into a song. I do notice that it's the order of flats in a key sig when you leave it major.

B E A D G C F (major)
Bb Eb Ab D G C F (natural minor)
Bb Eb A D G C F (Dorian)
Bb E A D G C F (Mixolydian)

Not nearly as entertaining as I had hoped it would be. **rueful smile**
