The Symphony No. 6 in B minor, Op. 54 by Dmitri Shostakovich was written in 1939, and first performed in Leningrad on 21 November 1939 by the Leningrad Philharmonic Orchestra under Yevgeny Mravinsky.
Symphony No. 6 is in three movements and is approximately 30 minutes in length:
The Sixth Symphony is unusual in structure, beginning with a long and introspective slow movement, followed by two short movements: a scherzo and a "full-blooded and debauched music-hall galop".
According to music critic Herbert Glass, the "entire [first] movement is based on the cell of a minor third, with a second theme - which follows without transition - the motif of a diminished seventh, with the trill at its close forming the third major ingredient of the movement - the two themes and the trill combined as a sort of super-theme. The composer lays this out as clearly as if he were teaching a music-appreciation class: do listen for it. Chamber music effects abound with, for instance, piccolo or flute, eerily alone or accompanied by the B-flat clarinets. There are walloping climaxes, too, each of which dies away into the gloom. Note, too, the composer's wonderful spotlighting of the melancholy English horn, a lone figure after the din has evaporated."
The third movement galop is the movement Shostakovich himself thought was most successful. Music critic Daniel Hathaway noted that in the third movement, [the] "Snare drums ratcheted up the riot of brutal sound in the Scherzo and references to the William Tell Overture and laughing trombones added a hilarious burlesque quality to the finale." On average, the first movement is 15–20 minutes long, the second movement is 4–6 minutes long, and the third movement is 5–7 minutes long.
This symphony is scored for piccolo, 2 flutes, 2 oboes, cor anglais, 4 clarinets (3rd doubling Eb clarinet, 4th doubling bass clarinet), 3 bassoons (3rd doubling contrabassoon), 4 horns, 3 trumpets, 3 trombones, tuba, timpani, snare drum, bass drum, cymbals, triangle, tambourine, tam-tam, xylophone, harp, celesta and strings.
