Where salsa comes from
3.Son: the direct parent

The most important ancestor of salsa is son cubano, or just “son.” It started in eastern Cuba in the late 1800s. Son used a small guitar called the tres, plus bongó drums, plus that African call-and-response singing.
In the 1940s, a bandleader named Arsenio Rodríguez added conga drums and more horns. This son montuno sound is almost the same band setup salsa still uses today: piano, bass, congas, horns, and a singer trading lines with a chorus.
