The Bandoneón
is a type of concertina particularly popular in Argentina. It plays an essential role in the orquesta tipica, the tango orchestra. The bandoneón, called bandonion by its German inventor, Heinrich Band (1821–1860), was originally intended as an instrument for religious music and the popular music of the day, in contrast to its predecessor, the German concertina (or Konzertina), considered to be a folk instrument by some modern authors. German sailors and emigrants to Argentina brought the instrument with them in the late nineteenth century, where it was incorporated into the local music.

About the Bandoneón
"It's the difference between a lemon and an orange," Piazzolla once said in an intervie w in New York. "The bandoneón is an orange, the accordion is a lemon. The accordion has an acid sound, a sharp sound. It's a very happy instrument. The bandoneón has a velvet sound, a religious sound. It was made to play sad music."
