Keyboard Sonata

The original use of the term sonata to differentiate instrumental from vocal works was often retained in the Baroque period.  A number of keyboard compositions therefore bear the title "sonata' though they do not resemble either of the two typical sonata types of the Baroque, sonata da chiesa or sonata da camera.  Some of these sonatas consisted of several movements, whereas others had only one.  Generally, simple binary or ternary forms were used for individual movements, which varied from dance-like character to song types, usually homophonic in texture.  The greatest exponent of the keyboard sonata in the Baroque was Domenico Scarlatti.
