Piano sonata

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 (Scarlatti, Liszt, Scriabin, Medtner, Berg), others with two movements (Haydn, Beethoven), some contain five (Brahms' Third Piano Sonata, Czerny's Piano Sonata No. 1) or even more movements. The first movement is generally composed in sonata form.
