Hello dunno how active this place is but in case some one knows, I’m wondering how necessary it is that the notes in the melody match up with the notes in the underlying chord?
I forget which chapter it was but I remember in the first book the rule was that notes not in the chord shouldn’t occur on a strong beat and if they do then they must resolve on a note within the chord. However there are several examples that sound good but do not follow this rule, e.g. Undertale by Toby Fox Chords, Melody, and Music Theory Analysis - Hooktheory both the intro and the verse. Some measures match up totally but there are a handful of measures that do not.
So I’m wondering, how does one write compatible melodies for a given set of chords if this rule is in fact not that strict?
