Comment: Please see his work-list in our homepage. There are ten sonatas and six sonatinas for two-hands. For four-hands, each is one and four. If he had not composed any sonatina, he would have disappeared from our music-history. Many people learning piano know his sonatinas. In Kuhlau's letter to his friend, he wrote "your daughter have praised my sonatinas but I have compose many sonatas for advanced students." It is unfortunate that most of his sonatas are out of print.
