Two works often identified and even published as piano concertos by Haydn, and commonly taught to younger piano students, are actually Divertimenti, grouped in Hob. XIV. Specifically, they are Hob. XIV:3, and Hob. XIV:4. However, another work of similar technical difficulty that is also identified and published as a concerto is the Concerto in F, Hob. XVIII:F1.
