What is the longest symphony?
Symphony No. 3 (Mahler)
The last movement in particular had a triumphant critical success. The Swiss critic William Ritter, in his review of the premiere given in 1902, said of the last movement: "Perhaps the greatest Adagio written since Beethoven". Another anonymous critic writing in the Allgemeine Musik-Zeitung wrote about the Adagio: "It rises to heights which situate this movement among the most sublime in all symphonic literature". Mahler was called back to the podium 12 times, and the local newspaper reported that “the thunderous ovation lasted no less than fifteen minutes.”[18]
