TOSCA by Giacomo Puccini is proposed according to the concept of the experimental project of the Theater and marks new results around the applied search to the repertoire of the Italian melodrama. Piccolo Lirico exalts the talent of the singers (all professionals and also perfect actors) and the characters of which the most dramatic of the Puccini's operas repertoire are famous. The singers are selected after a competitive process and receive training in acting: a now internationally known soprano Amarilli Nizza started her career as Traviata at the Piccolo Lirico some ten years ago. The duration of the shows is about 90/100 minutes, during which the melodrama and the theater are melted as only form of expression inside a virtual context enriched by new suggestions and original ideas, as the run in carriage of Tosca after the killing of Scarpia and the final in which Tosca returns as eternal heroin of the masterpiece. The Independent of London has inserted this opera among the "top ten " events to see in Italy. The New York Times has defined our Tosca "touching", "charming" and the project has received various prix for "courage of enterprise " and "innovation".The biggest challenge was that of adapting the music to the new requirements. The revolutionary idea was using new midi technologies, fine-tuning and continuously improving sound sampling and effects. The music is played by four pianists who have been trained in the new method by the director after having developed and prepared the keyboards and followed the acoustic part in order to achieve the best results. The music adaptation and the sound sampling have improved each season, and the audience has the feeling of listening to music played by a 60-element orchestra. The main innovations deal with virtual, amazing stage sets with singular effects. Piccolo Lirico Teatro Flaiano is a theatre nearly hidden in the central heart of Rome (the untouched Renaissance area between the Pantheon, the Collegio Romano, and Torre Argentina archeological setting). It 's an elegant jewel box.
