'''Symphony No. 3 in E flat major''' (Opus 20; subtitled ''First of May'') by Dmitri Shostakovich was first performed by the Leningrad Philharmonic Orchestra and Academy Capella Choir under Aleksandr Gauk on 21 January 1930.
Similar to the Second Symphony, it is an experimental choral symphony in four continuous sections:
#Allegretto - Allegro
#Moderato: 'V pérvoye, Pérvoye máya'
The symphony lasts around 25 to 30 minutes. The finale sets a text by Semyon Isaakovich Kirsanov praising May Day and the revolution. Interpretation is difficult: in a letter to Boleslav Yavorsky, Shostakovich said that the work "expresses the spirit of peaceful reconstruction"; on the other hand, most of the material preceding the finale is dark and sometimes sardonic in tone.
