Glinka refers to Mikhail Ivanovich Glinka, a prominent Russian composer of the 19th century, often considered the father of Russian classical music. He is best known for his operas, such as A Life for the Tsar and Ruslan and Lyudmila, which incorporate Russian folk themes and melodies, setting the stage for future composers. Glinka's work laid the foundation for the Mighty Handful, a group of Russian composers who sought to create a distinct national style in music. His innovative use of harmony and orchestration influenced many later musicians, making him a key figure in the development of Russian music.
