What's funny is that the dewd never said anything about playing an F or D. So it wouldn't even be the mode you guys were considering (E F G# A B C# D E). Take the chord progression and add a 5th to it and you'll see. A5 (A-E), C#5 (C# - G#), here's where it probably wouldn't work... G#5 (G#-D#), B5 (B-F#). So unless the G#5 is G#dim and the B5 is a B7b5, it wouldn't work (A harmonic major included). With just the root notes it looks like A major (or any number of scales), but with what I added it now looks more like E major (A lydian, E harmonic major, ...). Really depends on what the chords were with the root, cause there's quite a few that could fit.

u10ajf. Had a cool idea, and here's another one. First you take the E harmonic major, and you write out all the notes that are in the scale like this.

E, F#, G#, A, B, C#, D#

Start with the E, then skip the next note, then G#, skip the next note, then B. Write that down.

E, G#, B - Thats a major chord.

Then do the same starting with the next note, F#.

F# A C# - minor chord.

Do them all and you should have.

E, G#, B - major
F#, A, C# - minor
G#, B, D# - minor
A, C#, E - major
B, D#, F# - major
C#, E, G# - minor
D#, F#, A - diminished

This will tell you the simple triads of the chords that exist. Major, minor, diminished, and augmented. Everything else is an extension of that chord. Say if you added D# to the Emajor chord, you now have a EM7 chord.

Here's how you can tell if there major, minor, diminished or augmented.

E:---------:----------:---------:----------|
B:---------:----------:---------:----------|
G:--4------:---4------:--3------:--5-------|
D:--6-(9)--:---5-(9)--:--5-(8)--:--6-(10)--|
A:--7-(11)-:---7-(10)-:--7-(10)-:--7-(11)--|
E:---------:----------:---------:----------|
----Major--:---Minor--:--Dim.---:--Aug.

Here are the chord patterns of each type. The numbers in (*) are the same note as the played fret above, if you didn't realize. Hope this helps.
