This thesis (written in Chinese) is an attempt at a survey of cello playing techniques during the Baroque period, particularly of the first half of the 18th century. Chapter 1 provides a description of the early history of the cello, and its position in the modern violin family. Chapter 2 is devoted to a discussion of cello playing techniques during the first half of the 18th century, focusing particularly on playing posture, shape of both hands, bowing and vibrato, and the discrepancies thereof between 18th century and modern performance practice. Chapter 3 applies the preceding discussion to Bach's Suite for Solo Cello in C Minor, discussing details in the application of Baroque performance technique, and providing suggestions regarding style and certain technical problems.
