Amilcare Ponchielli (Italian: [aˈmilkare poŋˈkjɛlli], 31 August 1834 – 16 January 1886) was an Italian composer, mainly of operas. He was married to the soprano Teresina Brambilla.
Born in Paderno Fasolaro (now Paderno Ponchielli) near Cremona, then Kingdom of Lombardy-Venetia, Ponchielli won a scholarship at the age of nine to study music at the Milan Conservatory, writing his first symphony by the time he was ten years old.
Two years after leaving the conservatory he wrote his first opera—it was based on Alessandro Manzoni's great novel The Betrothed (I promessi sposi) -- and it was as an opera composer that he eventually found fame.
His early career was disappointing. Maneuvered out of a professorship at the Milan Conservatory that he had won in a competition, he took small-time jobs in small cities, and composed several operas, none successful at first. In spite of his disappointment, he gained much experience as the bandmaster (capobanda) in Piacenza and Cremona, arranging and composing over 200 works for wind band. Notable among his "original" compositions for band are the first-ever concerto for euphonium (Concerto per Flicornobasso, 1872), fifteen variations on the popular Parisian song "Carnevale di Venezia", and a series of festive and funeral marches that resound with the pride of the newly unified Italy and the private grief of his fellow Cremonese. The turning point was the big success of the revised version of I promessi sposi in 1872, which brought him a contract with the music publisher G. Ricordi & Co. and the musical establishment at the Conservatory and at La Scala. The role of Lina in the revised version was sung by Teresina Brambilla whom he married in 1874. Their son Annibale became a music critic and minor composer. The ballet Le due gemelle (1873) confirmed his success.
