Salsa music originated in the 1930s-1960s as Latin American immigrants in New York fused their diverse musical styles. The word "salsa" comes from the Latin American sauce used to spice up food, and was later yelled by musicians to introduce energetic acts. Salsa features percussion instruments like congas and timbales, along with piano, bass, horns, and vocals singing about love, culture, or patriotism. It has a flexible structure divided into "playing abajo" and "playing arriba" sections, and has been performed by famous artists like Fania All-Stars, Hector Lavoe, and Celia Cruz.
