I've been listening to a lot of the earlier Beatles lately, and focusing on George's harmonies.
Seems to me like he was always mixed really low by George Martin when they were doing three part. For example, "This Boy", "I Feel Fine", or (to a lesser degree) "I'll Get You". Sometimes to hear his harmonies, I almost have to "reverse engineer" them - peck out Paul's upper and John's lower voices, then figure out where George's would "have to be", go back and listen, and voila - it was there all the time! I wonder why George Martin did that ... is that the standard way to mix 3 part harmony - emphasis on the upper and lower harmonies at the expense of the middle? I'm going to listen to "Yes it Is" next, I think, and see how things worked there.
I also think he had the harder harmonies most of the time. Paul and John's could almost always be an independent melody, like the Everly Bros. did a lot. But George had to sort of sing the note that was "left over" that the other two didn't sing, which though it sounded awesome, was maybe not as intuitively melodic ... harder to sing maybe, at least for me.
What do you singer/musicians think?
And lastly, another question for this esteemed forum - do you think George figured out all his harmonies, or John/Paul said something like "Here, George, here's your part"? My bet is on the former, but who's to say?
