The Symphony No. 4 in B♭ major, Op. 60, is the fourth-published symphony by Ludwig van Beethoven. It was composed in 1806 and premiered in March 1807 at a private concert in Vienna at the town house of Prince Lobkowitz. The first public performance was at the Burgtheater in Vienna in April 1808.
The symphony is in four movements. It is predominantly genial in tone, and has tended to be overshadowed by the weightier Beethoven symphonies that preceded and followed it – the Third Symphony (Eroica) and the Fifth. Although later composers including Berlioz, Mendelssohn and Schumann greatly admired the work it has not become as widely known among the music-loving public as the Eroica, the Fifth and other Beethoven symphonies.
