🇩🇪Johann Sebastian Bach ： Invention no.9 f-moll BWV 780

The two voices proceed as if in dialogue, with short motifs passed between the upper and lower parts as the music unfolds. Each voice moves independently while overlapping with the other to create a sense of tension and release. Use the cadential points, like punctuation, to shape the phrases and give the piece an uninterrupted overall flow. In practice, examine the direction and dynamics of each voice separately; with both hands, avoid assigning a fixed main voice and instead shift the balance as the motif is passed between parts. Clear articulation and a steady pulse are essential, while ornaments should be added naturally without interrupting the flow, bringing out the delicate dialogue and forward momentum.
