This is a quick 11-page guide to the sonata form theory that discusses the five types of sonata forms in the context of a structural understanding of exposition, development, and recapitulation. The manual also discusses the types of expositions (two-part, continuous, trimodular block, monothematic, and three-key), as well as defines sonata-form nomenclature, such as main thematic zones, transition, medial caesura, caesura fill, essential expositional closure, and essential structural closure.
