Symphony No. 6 in A minor by Gustav Mahler is a symphony in four movements, composed in 1903 and 1904 (revised 1906; scoring repeatedly revised). Mahler conducted the work's first performance at the Saalbau (de) concert hall in Essen on May 27, 1906. It is sometimes referred to by the nickname Tragische ("Tragic"). Mahler composed the symphony at what was apparently an exceptionally happy time in his life, as he had married Alma Schindler in 1902, and during the course of the work's composition his second daughter was born. This contrasts with the tragic, even nihilistic, ending of No. 6. Both Alban Berg and Anton Webern praised the work when they first heard it. Berg expressed his opinion of the stature of this symphony in a 1908 letter to Webern:
