G/D
G Major over D · 3 fingerings
A slash chord: a G major triad with D in the bass instead of the root. The chord above stays the same — only the lowest note changes — which lets G/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.
