The chorus is also not what most would consider a traditional “hook” (though, that’s probably the point). Plus, the pre-chorus is doubled, and it precedes (I mean, “abuts”) no chorus the second time, making it seem like maybe this section should be called the chorus instead — but yeah, he didn’t name the song “Get Your Money,” did he? So there. The guitar plays solid chord types I and ii, and you can hear the I, IV, and V chords in what the choir is singing as well, but whether they’re fully there is somewhat subjective since they’re only harmonizing thirds and not whole triads.
By paying close attention to your playing and constantly giving yourself feedback, you can focus in on the moments that give you the most trouble and work at those specifically. One additional way to give yourself feedback might be to record yourself. If I record myself playing my Errol Garner tune, I can even compare it to the original, and make notes about the spots where I’m not quite getting it right!
