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.

Instead of thinking in terms of chords, I think of voice-leading; that is, melody line and bass line, and where the bass line goes. If you do that, you'll have the right chord. [These voices] will give you some alternatives, and you can play those different alternatives to hear which one suits your ear... Keep the bass line moving so you don't stay in one spot: if you have an interesting bass line and you roll it against the melody, the chords are going to come out right.

There was always some kind of strain, but it was workable. The bigger you get, the more of a strain it is, because in your everyday life, you're less used to compromising. As you get bigger, you have your own way. But in a partnership you always have to compromise. … When you get into a partnership, you're not the boss. There's no boss. That makes it hard.

I wanted to sing other types of songs that Simon and Garfunkel wouldn't do. "Mother and Child Reunion" for example, is not a song that you would have normally thought that Simon and Garfunkel would have done. It's possible that they might have. But it wouldn't have been the same, and I don't know if I would have been so inclined in that direction. So for me it was a chance to break out and gamble a little bit … The breakup had to do with a natural drifting apart as we got older and the separate lives that were more individual. We weren't so consumed with recording and performing. We had other activities … there was no great pressure to stay together other than money, which exerted very little influence upon us. … We didn't need the money.
