27 Most Famous Instruments Ever Made

If sound could swirl like a storm, it would sound like a Leslie speaker. Invented in the 1940s, its rotating horns and spinning drum create that famous trembling echo, like voices moving in circles. First paired with the Hammond organ, it later found its way into guitars and even vocals: from The Beatles’ “Lucy in the Sky with Diamonds” to Pink Floyd’s psychedelic landscapes.

The Leslie didn’t just amplify music; it reshaped it. The first time people heard that spiraling tone, it felt almost alive.
