People might think that Mozart was a naïve guy who left for others to write the librettos of operas. If you look carefully you notice otherwise. There is something very consistent in what he wrote, not only in terms of music but also in the sense of universal humanitarian values.
At the end of the opera “Die Entfuhrung aus dem Serail”, the hostages are released and people dance in rejoice. The celebration of humanity, without religion, without border. Unity of men beyond the classes, races, and cultures were the penetrating theme of ALL his works. Mozart was a forerunner of John Lennon.
