A look back at the violent conflict between the two leading figures of musical modernity, Arnold Schönberg and Igor Stravinsky, in the first decades of the 20th century. Although Arnold Schönberg and Igor Stravinsky both had a decisive influence on the fourth art, their creations remained diametrically opposed. While the Austrian developed the dodecaphonic method, placing the twelve notes of the chromatic scale at the heart of the composition technique to the detriment of tonality, his Russian rival based his practice on stylistic eclecticism. Their supporters formed two opposing camps, and the two composers - one the father of the Second Viennese School, the other of Neoclassicism - became, in the wake of their successes, the figureheads of a conflict that marked the history of music by its duration and intensity.
