Richard Strauss's Alpine Symphony will be performed in Armenia for the first time with the full orchestra The work will be performed by the Armenian National Philharmonic Orchestra on February 28 under the baton of artistic director and principal conductor Eduard Topchjan. The evening will feature musicians from Switzerland and Germany who will play the symphony with Wagnerian tubes. It premiered on October 28, 1915. For his mature work, Strauss designated an ensemble of well more than 100 performers, including an abundance of brass and percussion, as well as such instruments as organ, wind machine, celesta, and two sets of timpani. Although Strauss called his work a symphony, it bears none of the characteristics of that form. Instead of the standard four movements, An Alpine Symphony is written in one uninterrupted flow of music (roughly 45 minutes in performance length), portraying distinct episodes on the climb.
