By the time Bach relocated to Leipzig, he had already composed a number of masterpiece works. During his pivotal years at Köthen, he composed his Inventions and Sinfonias. These pieces, although typically overshadowed by his larger works such as The Well-Tempered Clavier, show Bach’s maturity as they serve as a fundamental tool for learning the piano.On this album, recorded in Leipzig, pianist Zhu Xiao-Mei does an extraordinary job of bringing out the musical density in these pieces.
