Wolfgang Amadeus Mozart (1756-1791) was among the most influential composers of the classical period. Throughout his life, Mozart composed fourteen piano variations and presented elegance in them in his own way. This thesis focused on Mozart’s later work—Variations on D Major for Piano, K. 573, and the research was divided into five chapters.
Chapter One was an introduction to the research motivation, purpose, scope and method of K. 573. Chapter Two discussed the work in two parts. Section One discussed Mozart’s composing background in terms of his early, middle and late period. The creation background of K. 573 was also introduced. Section Two described the origins of variations as well as the features of K. 573. Chapter Three analyzed the music according to the theme and characteristics and techniques of each variation. Chapter Four studied the musical interpretation and piano techniques. The discussion was based on thoughts of the author’s actual performing experiences. Chapter Five was the conclusion which summarized research findings from previous chapters.
