Symphony No. 7

The three years which elapsed between the completion of the score and the symphony’s premiere witnessed dramatic changes in Mahler’s life and career. In March 1907 he had resigned his conductorship of the Vienna State Opera, as the musical community in Vienna turned against him (which was why he chose Prague for the work’s debut);[7] on 12 July his first daughter died of scarlet fever; and, even as she lay on her deathbed, Mahler learned that he was suffering from an incurable heart condition. Musicologists[who?] surmise that this is why the optimism and cheerfulness of the symphony was subsequently tempered by the small but significant revisions Mahler made in the years leading up to its premiere.
