An idea from the triad thread. Briefly, you can superimpose some triads
over other chords which color the original chord in some way. These may
just be extended tertian structures or actual triads over other chords. You
can then think very simple triadic melodies based on the super imposed
triad rather than the fundamental tones.

Some possibilities using just major triads:

C major + C (plain), G (more colorful), D (bright and lydian sounding)
Cm7 + Eb, Bb, or F
C half-diminished + Bb (bright sounding dark chord=Cm7b5#2)
C13b9 = A/C7
C7#9b13=Ab/C7
C7b5b9=Gb/C7
C9#11=D/C7
C7sus + Bb or F
Cmaj7#5 + E
Cm maj7 + G

A standard progression like:

Dm7 - G7 - Cmaj7 becomes:

C/Dm7 - E/G7 - G/Cmaj7

or another progression:

Dm7b5 - G7 - Cm becomes:

C/Dm7b5 - Eb/G7 - G/Cm maj7

More later if anyone is interested.
