Two days ago, I learned the bass part for "She Knows Me Too Well," and yester-day I refined a few notes in the chorus that I had wrong initially. I'm pretty sure the song is in B major, but there are some A naturals (accidentals in B major) that musically highlight various sentiments in the lyrics that are sung above them.
The A naturals occur in the second half of every other line in the verses. In the first verse, in the line "Sometimes I have a weird way of showin' my love," they're under "showin' my love," musically illustrating that oddness. In the line "I treat her so mean, I don't deserve what I have," they're under "deserve what I have," illustrating that incongruity.
In the second verse, in the line "I get so jealous of the other guy," the A naturals are under "other guy," musically illustrating the foreignness of "other." In the line "When I look at other girls, it must kill her inside," they're under "kill her inside," musically illustrating that pain.
