The first movement embraces a loose sonata form. The key areas provide a continuation of the tonal juxtaposition displayed in earlier works (notably the Symphonies No. 6 and No. 7). The work opens with a hesitant, syncopated rhythmic motif (which Leonard Bernstein (1918-1990) suggested is a depiction of Mahler’s irregular heartbeat, which is heard throughout the movement).

The brief introduction also presents two other ideas: a three-note motif announced by the harp that provides much of the musical basis for the rest of the movement, and a muted horn fanfare that is also heard later. The main theme quotes the opening motif of Ludwig van Beethoven (1770-1827)‘s Piano Sonata No. 26 “Les Adieux”, Op. 81a, which coincidentally marked a turning point in Mahler’s early musical career as he performed “Les Adieux” during his graduation recital in college.
