“The listener isn't aware that they are new notes, but the sound is pleasing to the ear. I change the key, and somehow it's fresh because you haven't heard those notes before.”
As quoted in "Paul Simon's Workshop at the Guitar Study Center" by Richard Albero and Fred Styles in Guitar Player (April 1975), p. 21
Context: I didn't want to repeat the same notes in the second verse that I used in the first, so I wrote out all the notes of the song and all the notes that were missing in the scale, given that there are twelve notes from octave to octave. All those notes that weren't in the scale were the ones I wanted in for the next verse. The listener isn't aware that they are new notes, but the sound is pleasing to the ear. I change the key, and somehow it's fresh because you haven't heard those notes before.

“There's a famous seaside place called Blackpool,
That's noted for fresh air and fun.”
"The Lion and Albert", line 1.
Albert, 'Arold and Others (1938)

“I tell you all this because it's important to note progress.”
2016, Howard University commencement address (May 2016)
Context: Racism persists. Inequality persists. Don’t worry — I’m going to get to that. But I wanted to start, Class of 2016, by opening your eyes to the moment that you are in. If you had to choose one moment in history in which you could be born, and you didn’t know ahead of time who you were going to be — what nationality, what gender, what race, whether you’d be rich or poor, gay or straight, what faith you'd be born into — you wouldn’t choose 100 years ago. You wouldn’t choose the fifties, or the sixties, or the seventies. You’d choose right now. If you had to choose a time to be, in the words of Lorraine Hansberry, “young, gifted, and black” in America, you would choose right now.
I tell you all this because it's important to note progress. Because to deny how far we’ve come would do a disservice to the cause of justice, to the legions of foot soldiers; to not only the incredibly accomplished individuals who have already been mentioned, but your mothers and your dads, and grandparents and great grandparents, who marched and toiled and suffered and overcame to make this day possible. I tell you this not to lull you into complacency, but to spur you into action — because there’s still so much more work to do, so many more miles to travel. And America needs you to gladly, happily take up that work.
