Thanks for the spanish.
It's funny the way that you write. I think that you laugh with my english too
Oh! in some site this chord is named Eaug
To the best of my knowledge, an E aug (E-G#-C) has the same notes as a C aug (C-E-G#), has the same notes as a G# aug (G#-C-E), they are just different inversions of each other. I think there may only be 4 truly different augmented chords:
1) The one that has a C in it (like the three chords we just named, with the notes C-E-G#, with the three different names),
2) The one that has a C# (with the notes C#-F-A; named C# aug, F aug, A aug, respectively),
3) The one that has a D (with the notes D-F#-A#; named D aug, F# aug, and A# aug, respectively),
4) And the one that has a D# (with the notes D#-G-B; named D# aug, G aug, B aug).
I've usually seen it used as a 5th chord on the way back to the root chord - like the first chord in "Oh, Darling".
I have to say, I have never seen an augmented chord used in the fashion these guys did in that song (All My Loving). If I had to guess, maybe it's an old music hall technique Paul heard from his father when he was growing up and his father played in bands. Any body else have any thoughts on the use of the augmented chord in that fashion?
