I'm unclear how we are expected to know which 10 you want. OK, a few names are obvious, such as Vivaldi and maybe Scarlatti (at least Alessandro but didn't the son spend most of his life in Spain?) but what about Puccini, Donizetti, Mascagni, Leoncavallo, Albinoni, Respighi, Salieri, Cimarosa, Pergolesi, Tartini, Torelli and the contemporary Einaudi? Many others also existed. Should you not include some hints?
