F/D
F Major over D · 2 fingerings
A slash chord: a F major triad with D in the bass instead of the root. The chord above stays the same — only the lowest note changes — which lets F/D walk the bass by step through a progression while the harmony holds. A simple trick that makes ordinary chord sequences sound considerably more composed.
