The Third Symphony is a good-natured, triumphal, and deceptively simple-sounding piece. The symphony's first performance was given by the Helsinki Philharmonic Society, conducted by the composer, on 25 September 1907. There are themes from Finnish folk music in the work's early chords. Composed just after his move to Ainola, it contrasts sharply with the first two symphonies, with its clear mode of expression developing into the marching tones of the finale. His Fourth Symphony was premiered in Helsinki on 3 April 1911 by the Philharmonia Society, with Sibelius conducting. It was written while Sibelius was undergoing a series of operations to remove a tumour from his throat. Its grimness can perhaps be explained as a reaction from his (temporary) decision to give up drinking. The opening bars, with cellos, basses and bassoons, convey a new approach to timing. It then develops into melancholic sketches based on the composer's setting of Poe's "The Raven". The waning finale is perhaps a premonition of the silence Sibelius would experience twenty years later. In contrast to the usual assertive finales of the times, the work ends simply with a "leaden thud".
