To keep the "music teachers" happy some "scarry stuff".....In reference to the previous two scales.... when the "added note" of the chord/scale goes downward not only does it sound cool it is called diminished......when the added note of the chord scale goes upward and has a lonesome sound looking for a home it is called augmented

The Blues thread has some wonderful stuff on this....
