Symphony No. 1 in B-flat Major, Op. 38, symphony by German composer Robert Schumann that premiered on March 31, 1841, in Leipzig and was conducted by Schumann’s friend Felix Mendelssohn. It is an intensely optimistic work and is the most frequently performed of Schumann’s four symphonies.
Schumann’s inspiration for this buoyant symphony, at least in part, was the poetry of the German writer Adolf Böttger, whose verses were popular with composers from Edvard Grieg to Richard Strauss for their imagery of springtime. The symphony’s first movement opens with a glorious brass fanfare that broadens into a majestic orchestral theme. There are gentle evening moods in the second movement, sprightly dances in the third, and an imaginative development of varied melodies in the fourth movement, which follows a sonata form.
