P. D. Q. Bach is a fictional composer invented by the American musical satirist Peter Schickele, who developed a five-decade-long career performing the "discovered" works of the "only forgotten son" of the Bach family. Schickele's music combines parodies of musicological scholarship, the conventions of Baroque and Classical music, and slapstick comedy. The name "P. D. Q." is a parody of the three-part names given to some members of the Bach family that are commonly reduced to initials, such as C. P. E., for Carl Philipp Emanuel Bach; PDQ is an initialism for "pretty damned quick".
