The three music halls differ in size and are constructed with different music genres in mind. The Santa Cecilia Hall can be used for large orchestral and choral symphonic concerts. The Sinopoli Hall, because of its greater acoustic flexibility, is more apt for a great variety of musical genres. This is also because the orchestra position can be modified with respect to the audience. The Petrassi Hall caters to more contemporary musical genres, theater performances and cinema. This is possible thanks to an inbuilt system that allows both the musical source and the audience to be shifted around and the sound reverberation tuned.
