The article examines the evolution of thinking of American and European composers of the early 20th century, the expansion of their musical horizons in connection with the birth and emergence of Early Jazz, a new rhythmic music in the South of the United States. Almost all famous composers of the beginning of the century, to one degree or another, turned to jazz, each in his own way refracting new rhythms and harmonies in their work.
