While we're on the subject of different harmonies, do you guys use Aug. 6 chords in your writing? As far as I know, Yngwie (to the best of my knowledge) does not use these chords but they are still a very cool sound.

I'm not sure what you mean by an augmented 6 chord. Can you give an example?

Yeah I can try, but its kind of a long topic.
Okay: play this progression:
E-----5-----5-----5---5---4----5------
B-----5-----6-----4---5---3----5--
G-----5-----7-----5---5---1----5----
D-----7-----7-----3---2---------7---
A-----0-----5-------------------0---
E--------------------------0---------
The 3rd chord in the progression is an Aug. 6th chord. In fact its called a German 6th. So the Roman Numerals would go i iv It+6 i6/4 V7 i.
Okay now for the explanation:
The aug. 6th chord got its name from the unusual interval that happens between the bass and one of the other voices (when written in 4 parts: bass tenor alto soprano) In my case, it is between the bass the (F note on the D string 3rd fret and the D# on the 4th fret of the B string) That interval is an augmented 6th which is how the chord got its name.
Notice that the 3rd chord in my example is basically an F7 chord (VI7) but it is NOT spelled that way in music theory. Notice that I referred to the (hypothetical) "7th" of the chord as a D# and not as Eb (as would have been the case if the chord was an F7).
If the D# was spelled as an Eb it would have to be treated as the 7th of any chord (it would have HAD to go down by step). Now notice that in the case of aug 6th chord, that note actually moved UP. (because it was not spelled or treated as the 7th of the chord)
An aug 6th chord is built on the b6 scale degree. (so in the case of A minor it would be built on note F).
The interval of an aug.6 which occurs between the bass and one of the upper voices (usually soprano but can be in the inner voice as in my case its between bass and alto) resolves so that the bass moves downwards to scale degree 5 and the upper voice (which makes the aug.6th interval with the bass) moves UP to scale degree 5. This is why it is important to spell it correctly.
So the "skeleton" of any aug 6th chord is that interval I talked about and it resolves outwards to scale degree 5 making an octave.
The aug 6th chord is a type of predominant chord.
Let me know if what I've explained so far made sense to you, and then I'll write about the 3 types of aug 6th chords. (they are German Italian, and French)

I don't have time to work this out on my imaginary guitar.  |

E-----5-----5-----5---5---4----5------
B-----5-----6-----4---5---3----5--
G-----5-----7-----5---5---1----5----
D-----7-----7-----3---2---------7---
A-----0-----5-------------------0---
E--------------------------0---------
The first triad is A minor (A C E)
The second triad is D minor (D F A)
the third chord is the German 6 chord (F A C D#)
The fourth triad is A minor/E
The fifth chord is E7 (E G# B D)
The last triad is A minor
Does this help?
Mike.
