Symphony No. 5 is the fifth symphony by Russian composer Dmitri Shostakovich, completed in 1937. The four-movement orchestral work juxtaposes brooding, melancholic passages with more extroverted, rhythmic material and employs traditional symphonic forms imbued with stark contrasts and sardonic undertones; written after official denunciation, it marked a turning point in Shostakovich's career and holds a prominent place in 20th-century symphonic repertoire.
