Nat King Cole in the context of "Filin (music)"

Filin (Spanish: filin) was a Cuban, but US–influenced, popular song fashion of the late 1940s to the early 1960s. The word is derived from feeling, and is sometimes spelled filin or even el filin. It describes a style of post-microphone jazz-influenced romantic song (~crooning).

The Cuban roots of filin were in the bolero and the canción. It was related to the trova: in fact, filin was sometimes regarded as a renewal or reinvigoration, of the old trova. Some Cuban quartets, such as Cuarteto d'Aida and Los Zafiros, modelled themselves on U.S. close-harmony groups. Others were singers who had heard Ella Fitzgerald, Sarah Vaughan and Nat King Cole. Filin singers included César Portillo de la Luz, José Antonio Méndez, who spent a decade in Mexico from 1949 to 1959, Frank Domínguez, the blind pianist Frank Emilio Flynn, and the great singers of boleros Elena Burke and the still-performing Omara Portuondo, who both came from the Cuarteto d'Aida.
