Mahler's 6th Symphony is one of his most complex and ambitious pieces, though it retains a firmly classical structure throughout. It has notorious performance problems such as the order of the middle movements, and the symphony within a symphony final movement. It is also one of Mahler's most emotionally profound pieces, embracing life, death, and the struggles between these two forces. In the first movement, Mahler sets up the stakes for the battles to come and it's this movement we discuss today.
