Hi Guys,

Generally the terms augmented and diminished are only used to refer to altered 5ths in a chord. All other intervals are done with +/- or #/b preceding the number they are altering. E7add9 is redundant for E9, as add9 means add the numbered note without adding the 7th. The best term for E7 with F## (sometimes known incorrectly as G in this case) is E7+9 or E7#9.

Plus and Add are different terms and functions.

Thanks for that explanation.
I've been scratching my head a lot over this!

I've also been trying to figure out (again - lost the memory cells) the difference between:
E Major7 and E7

From what I remember .......................
E Major 7 ..... includes 1,3,5 and 7 notes of the scale.
E7 (Dominant 7th) Has same only uses a flatted 7th, the flatted 7th not being part of the key....1,3,5,b7


Memory Note For Me
......add9 chords for guitar
The add9 chord is a major triad with an additional ninth.
Unlike the regular 9th chord, the add9 has no seventh.


Major7th and Dominant 7th

A major 7th chord is formed by playing the root (1st) + 3rd + 5th + 7th notes of a major scale.
A dominant 7th is formed by simply lowering the 7th note a half step.

An Example:
Cmaj7 = C - E - G - B (7th note).

Lower the 7th note a half step, from B to Bb, thus

Dominant 7th = C - E - G - Bb.

Here are the dominant 7th chords in every key:
C7 = C - E - G - Bb
D7 = D - F# - A - C
E7 = E - G# - B - D
F7 = F - A - C - Eb
G7 = G - B - D - F
A7 = A - C# - E - G
B7 = B - D# - F# - A
C#7 = C# - E# (F) - G# - B
Db7 = Db - F - Ab - B
Eb7 = Eb - G - Bb - Db
F#7 = F# - A# - C# - E
Gb7 = Gb - Bb - Db - E
Ab7 = Ab - C - Eb - Gb
Bb7 = Bb - D - F - Ab
