Widely considered one of the most important and influential composers of the 20th century Igor Stravinsky net worth was a famous composer, pianist and conductor. Stravinsky's compositional career was notable for its stylistic diversity. He first achieved international fame with three ballets commissioned by the impresario Serge Diaghilev and first performed in Paris by Diaghilev's Ballets Russes: The Firebird (1910), Petrushka (1911), and The Rite of Spring (1913). The latter transformed the way in which subsequent composers thought about rhythmic structure and was largely responsible for Stravinsky's enduring reputation as a revolutionary who pushed the boundaries of musical design. His "Russian phase", which continued with works such as Renard, L'Histoire du soldat, and Les noces, was followed in the 1920s by a period in which he turned to neoclassicism. The works from this period tended to make use of traditional musical forms (concerto grosso, fugue, and symphony) and drew from earlier styles, especially those of the 18th century. In the 1950s, Stravinsky adopted serial procedures. His compositions of this period shared traits with examples of his earlier output: rhythmic energy, the construction of extended melodic ideas out of a few two- or three-note cells, and clarity of form and instrumentation.
Stravinsky has been called "one of music's truly epochal innovators". The most important aspect of Stravinsky's work, aside from his technical innovations (including in rhythm and harmony), is the "changing face" of his compositional style while always "retaining a distinctive, essential identity". Stravinsky's use of motivic development (the use of musical figures that are repeated in different guises throughout a composition or section of a composition) included additive motivic development. This is a technique in which notes are removed from or added to a motif without regard to the consequent changes in metre. A similar technique can be found as early as the 16th century, for example in the music of Cipriano de Rore, Orlandus Lassus, Carlo Gesualdo and Giovanni de Macque, music with which Stravinsky exhibited considerable familiarity. Over the course of his career, Stravinsky called for a wide variety of orchestral, instrumental, and vocal forces, ranging from single instruments in such works as Three Pieces for Clarinet (1918) or Elegy for Solo Viola (1944) to the enormous orchestra of The Rite of Spring (1913), which Copland characterized as "the foremost orchestral achievement of the 20th century". Stravinsky’s creation of unique and idiosyncratic ensembles arising from the specific musical nature of individual works is a basic element of his style.
