Jan Ladislav Dussek was a Czech classical composer and virtuoso pianist. He was an important representative of Czech music abroad in the second half of the 18th century and the beginning of the 19th century. Some of his more forward-looking piano works have traits often associated with Romanticism.

A piano sonata is a sonata written for a solo piano. Piano sonatas are usually written in three or four movements, although some piano sonatas have been written with a single movement, others with two movements, some contain five or even more movements. The first movement is generally composed in sonata form.
