Alban Berg (1885-1935) also wrote operas about poor or simple people. He wrote an opera called "Wozzeck" which is the tragedy of a man who is too simple to understand that people are being unkind to him and using him. Berg’s music is often built on the twelve tone series which he had learned from Schoenberg. Stravinsky’s (1882-1971) "The Rake's Progress" is in yet another style called Neo-classical because the music is made to sound a bit like music of the Classical Period. In England Britten wrote many great operas like "Peter Grimes" and "Billy Budd". In Russia Dmitri Shostakovich wrote "Lady Macbeth of the Mtsensk District". Most of them are about unfortunate people who want to be part of society but are not accepted.
