Editing Carl Philipp Emanuel Bach (section)

===Keyboard sonatas===
Bach was a prolific writer of keyboard sonatas, many of which were intended for his favored instrument, the [[clavichord]]. During his lifetime, he published more collections of keyboard music than anything else, in the following collections:
* ''Sei sonate per cembalo che all' augusta maestà di Federico II, re di Prussia'', 1742 ("Prussian" sonatas), Wq. 48.
* ''Sei sonate per cembalo, dedicate all' altezza serenissima di Carlo Eugenio, duca di Wirtemberg'', 1744 ("Württemberg" sonatas), Wq. 49.
* ''Achtzehn Probe-Stücke in Sechs Sonaten'', 1753 ("Probestücke" sonatas), Wq. 63.
* ''Sechs Sonaten fürs Clavier mit veränderten Reprisen'', 1760 ("Reprisen" sonatas), Wq. 50.
* ''Fortsetzung von Sechs Sonaten fürs Clavier'', 1761 ("Fortsetzung" sonatas), Wq. 51.
* ''Zweite Fortsetzung von Sechs Sonaten fürs Clavier'', 1763 ("Zweite Fortsetzung" sonatas), Wq. 52.
* ''Sechs Leichte Clavier Sonaten'', 1766 ("Leichte" sonatas), Wq. 53.
* ''Six Sonates pour le Clavecin à l'usage des Dames'', 1770 ("Damen" sonatas), Wq. 54.
* Six collections of ''Clavier Sonaten für Kenner und Liebhaber'', 1779–87 ("Kenner und Liebhaber" sonatas), Wq. 55–59, 61.
Much of Bach's energy during his last years was dedicated to the publication of the "Kenner und Liebhaber" collections (which also include fantasias and rondos, see below).{{sfn|''Complete Works''|loc=Vol. I/4, Preface}}

Wq. 64:1–6 are six [[sonatina]]s for keyboard, and Wq. 65:1–50 are fifty further keyboard sonatas. The Sonata in E-flat major, Wq.&nbsp;65:7, is based on ''Solo per il cembalo'', {{nowrap|BWV Anh.
