The second son of J.S. Bach, C.P.E. Bach was an important composer in his own right, as well as a writer and performer on keyboard instruments. He has always been the subject of significant scholarship and publication but interest has sharply increased over the past two or three decades from performers as well as music historians. This volume incorporates important writings not only on the composer and his chief works but also on theoretical issues and performance questions. The focus throughout is on relatively recent scholarship otherwise available only in hard-to-access sources.
