According to this article, it is possible to make a chord progression by just keeping one tone that remains constant in all chords of the progression.
Also, it gives these examples: Cadd9
F6
D
G
Asus
Bb
G
Cadd9
and F/C
G/C
D/C
G/C
Bb/C
Gsus/C
G/C
C
.
Finally, at the end of the article the writer suggests this: "Try any of the progressions above, and create a short 2-, 3- or 4-note idea that “more or less” works with most of the progressions."
So my question would be, how can I determine which notes can I play on those chord progressions?
