Step-by-step explanation:
Dominant Composer in Russian Music
The dominant force in Russian music who adopted a cosmopolitan style and whose works had wide appeal in Europe and North America is Pyotr Ilyich Tchaikovsky. Renowned for his symphonies and ballets, Tchaikovsky's compositions have stood the test of time and continue to be celebrated globally. Unlike the modernist composer Igor Stravinsky, whose work such as the Rite of Spring scandalized audiences with its avante-garde elements, Tchaikovsky embraced a more accessible, romantic style that resonated with a wider public.
During the Romantic era, which produced greats like Brahms, Schumann, and Chopin, Tchaikovsky's music thrived and was received with enthusiasm for its emotional depth and melodic richness. His ability to blend Russian melodies with Western compositional techniques allowed his work to transcend cultural boundaries, making him an international figure in classical music.
Moreover, Tchaikovsky's genius afforded him the status of not merely a national treasure but a global icon, whose influence spanned beyond the borders of Russia, captivating audiences in concert halls worldwide.
