The Spanish copla is pop or folk music that reached its peak popularity in the 1930s and 1940s. It’s music that would be recognized by most Spanish adults—sometimes with nostalgia, as in the case of some of our acquaintances in their 50s who explained that la copla was music their mothers sang in the kitchen.
See and hear a modern take on El emigrante, a copla in the voice of an emigrant—of which there were millions in the years after the Spanish civil war (1936-1939)—promising to never forget his beloved Spain.
