Girolamo (or Gerolamo) Barbieri (Piacenza 1808 - Piacenza 1871) is one of the most prolific 19th c. Italian composers of organ music. Orphan in his youth, he could not receive lessons, and learned music theory alone. He was appointed during several years as choirmaster in Caravaggio and then in Cremona. Then he comes back to Piacenza where he is elected as choirmaster of the cathedral. He becomes a disciple of famous Padre Davide, 17 years older than him, but his reputation is much lesser despite the many printed works.
