Winter Daydreams, symphony #1 by Pyotr Ilyich Tchaikovsky
From Wikipedia:
Tchaikovsky wrote his Symphony No. 1 in G minor, Winter Daydreams (or Winter Dreams) Op. 13, in 1866, just after he accepted a professorship at the Moscow Conservatory: it is the composer’s earliest notable work. The composer’s brother, Modest Ilyich Tchaikovsky, asserted that the symphony’s creation from beginning to end cost his sibling more labor than any other works and even involved considerable suffering. Even so, he remained fond of it throughout his life. Tchaikovsky wrote to his patroness Nadezhda von Meck in 1883 that he believed, “although it is in many ways very immature,” he still knows that “yet fundamentally it has more substance and is better than any of my other more mature works.”
