Add color without losing tenderness

Use add9, sixth, seventh, open, and suspended sonorities.

• Dm(add9) = D–F–A–E; keep the triad and add the ninth
• B♭maj7 = B♭–D–F–A; major triad plus major seventh
• A slash chord’s note after / is the bass note

Example: D and A alone form an open fifth. Add F for D minor; add E as well for Dm(add9).
