... and then discarded because the Beatles were so good - that they could!
Pilz on another thread pointed out that lesser bands, even IF they happened on some musical gem that was unique and great, would likely have made a fetish out of it, including it in anything they might have developed. But the Beatles were so good they just wrote it, recorded it, and threw it over their shoulder, never to look back!
I'll start with two of them:
1) Song: All My Loving. In the chorus, while Paul sings "All my loving ...", John and George do "Ooohs" in harmony. It's hard for me to say who does the upper vs lower harmony, but the point is that they do three chords, and the 2nd chord is just so friggin' wild it is like from another space-time continuum -
All my "Oooh #1" = C#m, right in there with the song's key of E.
"Oooh #2" = C augmented!! Where did this chord come from, a man on a flaming pie from outer space? I think, listening closely, that John or George's guitar is also strumming that chord.
"Oooh #3" = Back in comfortable territory - an E chord.
Does anyone who is musically literate know any other song that has a C augmented in the key of E (or I guess this might be called the major 6th chord)? More to the point, how do you think the Beatles decided on that chord? Is Paul or John the one more likely to have come up with it? Anybody on this forum know British popular music from the mid-1950s ... was there a popular song that used that chord progression? I know Buddy Holly liked it, but he used it in such a different way, it's hard to draw a line from there to here (Peggy Sue, and I think one or two others, too).
This chord has really got a hold on me since I realized what it was ... any and all opinions on it are very welcome!
2) Song: "Ticket to Ride" - Key of A, but the second time John sings "She's got a ticket to ri-hi-hide" , they do this G chord, but John's vocal doesn't have any note that's part of a G chord! Complete dissonance between melody and backing chord, but Lawdy, how it sounds awesome! It's pretty close to the defining part of the song for me ...
