Le Mancenillier, Op. 11, is a Creole-based composition for piano written by American composer Louis Moreau Gottschalk in Switzerland in the fall of 1848.[1] Dedicated to "Madame Mennechet de Barival", it was published in Paris with the subtitle Sérénade by his publisher 'Escudiers' in April 1851.[2] It is the fourth and last piece dubbed by musicologist Gilbert Chase the Louisiana Trilogy,[3] written between 1844 and 1846 when Gottschalk had not yet come of age.
