Laughing on the bus, playing games with the faces, She said the man in the gabardine suit was a spy, I said, 'Be careful, his bowtie is really a came… - Paul Simon

A man walks down the street
It’s a street in a strange world
Maybe it’s the third world
Maybe it’s his first time around … He looks around around
He sees angels in the architecture
Spinning in infinity
He says Amen and Hallelujah.

A man walks down the street
He says why am I short of attention
Got a short little span of attention

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.
