In the field of music theory, the term Sonata Cycle refers to the layout of a multi-movement work where the movements are recognizably in the forms of the tradition of classical music.
It differs from the term cyclic form in that there is no unifying motive or theme used in all the movements.
The standard sonata cycle has four movements, broken down as follows: The first movement is, by definition, written in sonata form, in a fast tempo (allegro), and in the home key of the overall piece.
Or, if used as the last movement, is in a fast tempo such as prestissimo, presto, or vivace.
In reference to performance or recording, Sonata Cycle almost always means the complete traversal of a set of works by a single composer.
