Until the 18th-century, music in Russia consisted mainly of church music and folk songs and dances. In the 19th-century, it was defined by the tension between classical composer Mikhail Glinka along with other members of The Mighty Handful, and the Russian Musical Society led by composers Anton and Nikolay Rubinstein. The later tradition of Pyotr Ilyich Tchaikovsky, one of the greatest composers of the Romantic era, was continued into the 20th century by Sergei Rachmaninoff, one of the last great champions of the Romantic style of European classical music. World-renowned composers of the 20th century include Alexander Scriabin, Alexander Glazunov, Igor Stravinsky, Sergei Prokofiev, Dmitri Shostakovich, Georgy Sviridov and Alfred Schnittke.
