In the post 103 we introduced a 7-notes scale, from each 3 or 4-notes chord of chord progression. See also post 83 about scales of chords versus chords of a scale.

A simpler 5-notes or sub-scale is the closure sub-scale of a 3-notes chord. E.g. if the Chord is the c-e-g, the closure sub-scale is the c-d-e-f-g, in other words the closed interval within a diatonic scale with ends the ends of the chord. Any melody with almost equal time to its notes within this sub-scale , and approximately using all notes ,will sound fitting to the harmony of the chord because at worse scenario statistically only 2 notes will be out of the chord and 3 notes inside the chord and 3>2.
