Marguerite Long, the most important French female pianist of the 20th century, left her stamp on a whole epoch of musical life in Paris. The Pedagogical Writings of Marguerite Long presents English translations of the two contributions of Marguerite Long to the literature of piano pedagogy. These translations of her pedagogical works, Le Piano and La Petite Methode de Piano, provide a window to the old French school of pianism as modernized by Long. Le Piano is a remarkable text offering piano playing techniques and pragmatic and philosophical musings and observations about life, musicians, careers, and more. La Petite Methode de Piano is a personal manifesto about how to introduce kids to music. Both works are treasures revealing Long's deep commitment to teaching and they are still stunningly relevant. In addition, John Ellis analyzes each work and puts it in historical context. He places special emphasis on Long's illustrious international career, her teaching, her rivalry with Alfred Cortot, and the impact of sexism on her. Ellis addresses the eclipse of Long's reputation by that of Cortot and fills a gap in the knowledge of Long's place in the history of pedagogical heritage.
