The son of a distinguished Russian singer, Stravinsky spent his earlier years in Russia, either in St Petersburg or, in the summer, at the country estates of his relatives. He studied music briefly with Rimsky-Korsakov but made a name for himself first in Paris with commissions from the impresario Diaghilev, for whom he wrote a series of ballet scores. He spent the years after the Russian Revolution of 1917 in Western Europe and in 1939 moved to the United States of America. There in the post-war years he turned from a style of eclectic neoclassicism to composing in the twelve-note technique propounded by Schoenberg. A versatile composer, inventive in changing styles, he may be seen as the musical counterpart of the painter Picasso.
