Alberto Williams (November 23, 1862 – June 17, 1952) was an Argentine composer of classical music, a pianist, a pedagogue, and a conductor.
Alberto Williams was born in Buenos Aires, in 1862. His maternal grandfather, Amancio Jacinto Alcorta, had been a respected diplomat and economist, and an amateur composer of salon music. Williams began studying the piano at age 8 with Pedro Beck. Six years later, he entered the Escuela de Música y Declamación (School of Music and Recitation) of the Province of Buenos Aires, where he received piano lessons from Luis José Bernasconi. He received a scholarship from the government of the Province of Buenos Aires in 1882 to study music composition at the Paris Conservatoire, where he was mentored by pianists Georges Mathias and Charles de Bériot, and learned harmony with Emile Durand and counterpoint with Ernest Guiraud. He furthermore took private lessons in composition from César Franck, who apparently became very fond of his student.
Williams published his first piano pieces during this period, including character and salon pieces and dances, and completed his Primera Obertura de Concierto (First Concert Overture, op. 15) for orchestra, before returning to Argentina in 1889. Upon arrival, he toured the rural pampas and became introduced to folk music of Argentina. His first composition to earn widespread success, "El Rancho Abandonado" (The Abandoned Hut), fourth number of a piano serie entitled En la Sierra (In Hill Country, op. 32, published in 1893) is a nostalgic lament of the rural life in the pampas, and includes a successful quotation of the Huella folk dance. In the 1890s and 1900, Williams mostly cultivated an international style strongly rooted in the Romantic tradition. After 1910, however, his compositions employed selected "Impressionistic" techniques and more dissonant harmonies without ever adopting a Modernist (or avant-garde) aesthetic. Around the same time, he resorted to Argentine folk themes and rhythms with increasing frequency, basing his piano and orchestral music upon adaptations of milongas, huellas and other rural genres. Williams founded the Buenos Aires Conservatory of Music (later known as Conservatorio Williams) in 1893, and established franchises in many cities and towns of the Argentine interior.
