Argentinian folk music composers Los Hermanos Abal are best known for founding a folk group in 1939. Their career high point came in 1942 when their song Carnavalito Quebradeño was used in the film La Guerra Gaucha. Virtu Maragno (1828-2004) sublimely harmonises the song for SATB choir. Argentinian born Maragno was a composer of classical opera and film music as well as a teaching and national academic. His harmonisation of Carnavalito Quebradeño displays elements of South American folk music. For aspiring four-part choirs Maragno's harmonisation of Los Hermanos Abal'sCarnavalito Quebradeño makes for an exciting alternative performance work.
