The birth of ska

Around independence, Jamaican musicians sped up and flipped the beat, and ska was born — a sound of optimism and motion.

By the late 1950s, Jamaican producers such as Coxsone Dodd and Duke Reid were pressing local recordings onto 45s to feed the sound systems, since imported American R&B was growing scarce and expensive. Studio players - session guitarists especially - took the shuffle beat of American R&B and pushed the emphasis onto the offbeat, while the drums leaned on traditional Jamaican marching and drumming patterns. That offbeat chop, cut on 45s from around 1959 onward and issued from studios like Federal Records and, from 1963, Dodd's own Studio One on Brentford Road, became ska: fast, brass-forward, and timed almost exactly to a nation about to declare independence in 1962.

Ska's origin story: Wikipedia; Coxsone Dodd's Wikipedia entry; Music Origins Project on Studio One. Exact "first" ska record and precise 1959 date remain debated among historians - treat specific attributions as probable rather than settled.
