Among his numerous works of sacred music, he published The Agony, a canto for tenor, baritone and organ, for Good Friday observations in 1843; the majority of his compositions from this period were lost, however.
[3] His treatise, Banks and Their Usefulness in Argentina, helped lead to his appointment to the Public Credit Administration, and he served as President of the Buenos Aires Stock Exchange from 1855 to 1857.
He christened the property Estancia Paso del Rey ("King's Ford Ranch") and, in 1860, established the municipality of Moreno (today a thriving suburb of Buenos Aires).
Alcorta lived in the placid estancia throughout his career in Government, and continued to compose music (writing a Gradual for the feast of Saint Martin of Tours in 1854, for example).
Much like his close friend, Juan Bautista Alberdi, Amancio Alcorta was both a valuable contributor to the survival of the constitutional republic in the perilous years after 1853, and, an important precursor to the development of music in Argentina.
