Carl Fasch was notoriously reluctant to have his music made public and even asked for much of it to be destroyed. What remains supports the view that Fasch was the true successor to C. P. E. Bach, with whom he shared keyboard duties at Frederick the Great’s court. The present sonata, which appeared in print and was well regarded during the composer's lifetime, shows him to be a minor master and an eloquent advocate for the eclectic expressive style then current in Berlin.
