Almost 8.000 scores from the mid-1700s to the end of the 20th century — not just opera, but also chamber music and symphonic music. The oldest are Il Ciro riconosciuto by Niccolò Jommelli of 1744 and 24 Capricci by Niccolò Paganini; among the most recent are scores by Luigi Nono (e. g. his major work of musical theater Prometeo, 1984) and Franco Donatoni (e. g. his arrangement of Bach’s Kunst der Fuge for orchestra, 1992). There are also a large number of “romances” that are still performed in Italy today, by Francesco Paolo Tosti and others, arrangements, and a range of works for musical education.
