The story

Before the bass player owned the low end, the piano's left hand was the rhythm section — and its signature move was the tenth: the root and the third stretched a tenth apart, striding under a right-hand chord. Teddy Wilson made it sing behind Billie Holiday, Art Tatum turned it into fireworks, and the whole swing-era piano tradition rests on it. Because the left hand carries a real root, these voicings sound complete and warm on their own, without a bass player — the opposite of the rootless modern grips. The reach is genuinely wide: a tenth is a stretch, and if your hand can't span it cleanly you roll it bottom-to-top, which is exactly how the old masters played it. Keep the left hand light and springy on the beat, let the right-hand chord fall just after, and the swing writes itself.
