Miguel Faílde Pérez (1852-1921) was a Matanzas cornetist and bandleader who, on New Year's Day 1879, premiered "Las Alturas de Simpson" — the piece Cuban musicology credits as the first danzón. Built on the Cuban cinquillo drawn from the older contradanza and habanera, Faílde's form became the island's dominant ballroom genre for the next half-century, and every charanga that followed, Arcaño's among them, was in some sense still dancing inside the room Faílde built.
