In May of 1913 The premier of the Ballet The Rite Of Spring caused a riot in a theater in Paris. Igor Stravinsky had created the music to do precisely that. It set aside the notion that an ordinary interrelationship between melody,harmony and form was mandatory. Instead, texture, dynamics and rhythm were a focus. This,in part makes it extremely elemental and primitive. In addition, a great deal of its melodic material is based on folk songs .Folklore was a phenomenon during that time period and Stravinsky used the material to create the essence of primitive energy. Also its metric complexity ,changes, syncopation ,and odd phrase groupings create a mood of mystery. The total effect is most successful at shocking the listener even today almost 100 years later. It is quite a work!
