🇩🇪Johann Sebastian Bach ： Sinfonia no.9 f-moll BWV 795

This contrapuntal miniature brings three independent voices into close connection through the exchange of the subject. From the opening, the lines overlap and create a continuous flow through the interplay of the melodic voices and inner-voice responses. The piece unfolds by developing a single musical idea, with changes in voice placement and density providing important points of interest. In performance, each voice should be clearly distinguished, while entries of the subject are brought out naturally and the pulse remains steady without becoming rigid. Ornaments should be handled lightly so as not to interrupt the flow; attention to phrase direction and the momentum toward cadences allows the transparent polyphonic texture to come fully alive.
