Carlo Rossini (1839 - c.1900), an Italian priest and composer, working in Pittsburgh, United States of America. Father Carlo Rossini was an Italian born and trained priest who was invited by Bishop Boyle, (Pittsburgh), to implement the ‘reforms’ of Pius X in his diocese. Though some of Fr. Rossini’s music may seem ‘dated’ to us now, and perhaps lacking some originality, he provided counltess parishes with suitable music for their weekly high Masses. The state of music in many churches c. 1900 was horrible. Though not explicity heretical as most modern church music is, a good ammount of music ‘pre-Moto Proprio’ was still unsuitable for Divine Worship, being theatrical and cliched. Fr. Rossini addressed this problem by arranging and composing simple music that even the most imcompetant and mediocre choirs could successfully sing. I’m sure it was quite a task to wean choirs away from the music they were used to singing, and in many cases the only option he had was to do it ‘with force’. Anyone who reads the Moto Proprio knows that Pius X intented to be obeyed, and that he expected the Bishops and Diocesan officials to employ whatever suitable methods were needed to ensure good music for Mass. To sum, Fr. Rossini did his part, (small or large as it may have been), in getting parished to do suitable music for Mass.
