Of early twentieth century opera composers, Richard Strauss certainly ranks among my favourites. One of his masterpieces is Der Rosenkavalier (premiered in 1911). There are many, many great scenes in this opera. I've noticed that people publish mostly or almost exclusively the Final Trio 'Hab' mir's gelobt' and the following 'Ist ein Traum' (brilliant pieces, for sure, no doubt about it !), and that's a bit unfair I think. Therefore, to counterbalance this a bit, I've decided to publish 10 minutes of the first act, starting with the orchestral opening, depicting the Marschallin (a married woman) and Octavian (her lover) making love at the break of day after spending another passionate night together. The passion continues in a different way in another excerpt, later on, also taken from the First Act. All the pictures are taken from the worldwideweb. The search and selection -done fast and merely on an intuitive basis- proved to be a nice and funny experiment. For people unfamiliar with this music I hope watching the video will make the opera more interesting and accessible to them.
