Filin (from the English word “feeling”) is a mid‑20th‑century Cuban song movement that blends the poetry and romanticism of bolero and Cuban trova with the harmonic language and phrasing of U.S. jazz. Characterized by intimate, crooning vocals, sophisticated jazz‑influenced chord progressions, and small‑combo accompaniment (guitar or piano with light rhythm section), filin favors subtle dynamics, rubato, and conversational phrasing. Its songs often use AABA or verse–refrain forms and highlight nuanced lyricism about love, memory, and urban nightlife. Emerging from Havana’s bohemian clubs and radio scene, filin modernized Cuban romantic song and became a key bridge between early trova/bolero and later currents such as nueva trova and jazz‑inflected Latin balladry.

Bolero is both a Spanish dance-music form from the late 18th century and, later, a Cuban song style from the late 19th century. The Spanish bolero emerged as a moderately slow solo or partner dance in 3/4 time, shaped by Andalusian song-dance traditions. It typically features guitar accompaniment and castanets, and its sung texts often follow the seguidilla stanza pattern. In Cuba, bolero evolved into a romantic ballad—most often in 2/4 (later also felt in 4/4)—performed by singers, trios, and salon ensembles. Cuban bolero emphasizes intimate, lyrical melodies, guitar-led accompaniment (often with requinto), and gentle Afro-Caribbean rhythmic undercurrents (habanera feel, soft bongo, claves), becoming one of Latin America’s quintessential love-song forms.
