"The Russian Opera" by Rosa Newmarch is a historical account written in the early 20th century. The work broadly discusses the development and evolution of national opera in Russia, focusing on composers such as Glinka, Rimsky-Korsakov, and Tchaikovsky, among others. It seeks to illuminate the cultural and musical backdrop against which these operas were created, providing insights into the influences and challenges faced by Russian composers throughout history. The opening of the book establishes the groundwork for understanding the complex history of music in Russia, detailing how early primitive music of the Slavs evolved amidst oppression and repression from church authorities. Newmarch introduces key historical figures and cultural movements that shaped Russian music, tracing the roots from the primitive traditions to the establishment of national opera as a legitimate art form. This opening highlights the conflict between natural artistic impulse and authoritative repression, setting the stage for a deeper exploration of significant composers and their works in subsequent chapters.
