Just 50 years ago, nobody knows the name Vivaldi. Today, his music is regularly heard in restaurants, shopping centres and on TV advertisements. But did you know that Vivaldi, born and brought up in Venice, was trained as a priest? That he produced literally hundreds of works of music, from concertos to oratorios? That he began his career as a violin teacher in one of the orphanages of La Serenissima? Did you know that he not only wrote many operas but for years also acted as impresario at performances of these and other works? What is the truth behind the ongoing rumours concerning an affair with the young singer Anna Girò? Was this why she was chosen to play the role of leading lady in his operas? And who was Paolina, Anna's supposed half-sister? Is it true that Vivaldi is buried in a pauper's grave in Vienna? Hidden Harmonies takes us back to the turmoil of the eighteenth century, cruising along canals past Baroque palaces and bustling theatres. We experience the carnival in Venice and travel to Florence, Mantua, Prague and Vienna. You are bound to find yourself enthralled by this artistic world of composers, castrati and prima donnas, kings, emperors and even the pope of Rome himself. This novel by historical novelist André Romijn (www.ma-trilogy.com) offers accessible insight into the life of a man whose constant struggle was a balancing act between victory and failure. How come his music is so famous today whilst just fifty years ago the name of Vivaldi was practically unknown? The novel is based upon historical facts.
