The music to which matadors would enter the bullfighting arena finds its origin in the Spanish military, where the fast-paced marching music, known as pasodoble (double step) was used to speed up troops. In the 19th century, the genre spilled from military barracks into the arena, as the music to guide the matador and the bull’s ‘dance’. The music was meant to build suspense and drama when the matador entered the ring and right before he killed the bull: a double pace towards the end.
