What is the chord structure of augmented and diminished chords? You know like the strucutre of a major chord is r 3rd 5th and minor is r b3 5. Also is major sevenths r 3 5 b7 and dominant sevenths r 3 5 7, or the other way round? Cheers

aug. = 1,3,#5
half dim. = 1,b3,b5
fully diminished = 1, b3, bb5

...if I remember correctly from my HS music theory class a few years back. the aug. and dim. denotes that the 5th is being moved. I'm not positive the fully dim. one is right.

If the 5th is flattend twice does that make it a 4th? Or am I talking out my arse?

Plus if anyone could clear up the Dom 7 and Maj 7 ones that would be good. And also thanks deville for the aug and dim

A triad is simply diminished, there is no half diminished triad. It's not until you
add the 7th that it would be half dim (b7) or dim (bb7).

Half-diminished: 1-b3-b5-b7
Fully Diminished: 1-b3-b5-bb7
Augmented: 1-3-#5
Someones knowledge of guitar companies spelling determines what amps you can own. Really smart people can own things like Framus because they sound like they might be spelled with a "y" but they aren't.

...
dim - 1 3 b5
*giggle*
dim = 1 b3 b5 -- two minor third intervals. Easy to remember, for some of us.

Zepp nailed this with his edit. Dim means the triad, half-dim/whole-dim refer to the added 7th being either a minor 7th (b7) or a diminished 7th (bb7).

Also... No, a double flat 5 or double flat 7, or any other double flat, is not the same as its simple enharmonic -- not that I'd ever use bb5 for anything, but that doesn't mean you couldn't -- while they're the same pitch, they function completely differently.
