The Baroque period was a period that continued the prosperity of the Renaissance

and created a new style. Known as the "Father of Music" John. Sebastian Bach, one of

the most important Baroque musicians. Bach uses the traditional classical suite

structure, fugue and counterpoint to form the polyphonic texture, and integrates and

innovates into his own unique style.

This research is divided into six chapters. The first chapter is the introduction,

and the second chapter is Bach's life, discussing Bach's youthful growth and the creation

of Weimar, Köthen and Leipzig. The third chapter introduces Bach's keyboard works,

as well as the style and characteristics of dance music used in keyboard works. The

fourth chapter analyzes Bach's "Partita" No. 1, BWV825 keyboard works, the musical

paragraphs and harmonic structure, and then completes the fifth chapter's performance

interpretation according to the style characteristics of dance music and the above

research. Finally, the conclusion of the sixth chapter is sorted out.
