G7

G Dominant 7th · 4 fingerings
The dominant seventh adds a flat seventh to the major triad, and that interval against the major third is what creates its restless, bluesy pull. G7 is the engine of blues, where whole progressions are built from dominant chords, and it's the classic V chord that drives a resolution home in jazz and pop alike.
