Tamara Stefanovich is known for her carefully curated programs in which she explores the evolution of specific musical genres from the 20th century to the present. Following last season’s concert dedicated to piano sonatas from Alban Berg to Pierre Boulez, she now presents a selection of different etudes—a genre that has long shed its original purpose as a mere finger exercise. Claude Debussy and others transformed it into a medium for extraordinary experimentation, as Stefanovich reveals in works ranging from Scriabin to contemporary composers Unsuk Chin and Liza Lim.
