Born in Rome, Capocci was trained in organ and harmony by his father
Gaetano (1811-1898) and in 1861 received a piano diploma from the
Accademia di Santa Cecilia in Rome. In 1875, he was appointed organist of the
Archbasilica of St. John Lateran. In 1898, he took over from his father as choirmaster at the Basilica. He also served in the Roman churches of
St. Ignatius and
St. Mary of Montserrat. Unlike his father, Filippo Capocci adhered to nineteenth-century musical aesthetics, avoiding the theatrical style, and dedicated himself to a style of performance and composition similar to that of the French organist
Alexandre Guilmant. His opportunity for wider recognition came in 1881 with the inaugural concert for the new Merklin organ at the Church of St. Louis of France. By this time, thanks to his friendship with Guilmant, the world's largest churches opened their doors to Capocci. Capocci was also one of the three foreign organists who performed in a series of organ concerts using the Cavaille-Coll organ at
Trocadero during the
1889 Paris World Fair. In 1890, his performance with Guilmant and Polleri for the inauguration of the new organ of William George Trice at the Basilica of the Immaculate Conception in
Genoa marked another point in favor of the
Cecilian Movement that resulted from his work as a performer and tester of new organs. Capocci also endorsed the proposal of the chapter of canons of St. John for the construction of two new organs that were installed after the renovation of the
apse built by
Pope Leo XIII. This work was commissioned by Nicholas Morettini, one of the first builders in Italy to endorse the principles of the reform.
Franz Liszt, while staying in Rome, sought to meet Capocci personally and expressed great esteem and friendship. In 1899, he was accepted as a member of the
American Guild of Organists. He was appointed a member of the organ faculty for the
Pontifical Institute of Sacred Music in 1911 but was never able to teach because of an illness that debilitated him for months until his death in Rome in July 1911. He was the mentor of several noted personalities, including
Queen Margherita of Italy and the
Brazilian composer and organist Furio Francheschini. ==Works==
