Wilhelm Friedemann Bach
Wilhelm Friedemann was an excellent organist, and took over teaching some of his father's students. In 1733 he was appointed as the organist at the Dresden Sophienkirche (St. Sophia's Church). While living in Dresden he continued to write music including harpsichord concertos, sinfonias, trio sonatas, harpsichord sonatas, and other smaller works for keyboard. He published his first music in 1745.
