Two-part (binary) form

About this item

Description Discusses the binary form of musical composition. Illustrates that the under-lying principle of this form is thesis and antithess. Distinguishes between the balance of phrases in a two-phrase sentence and the balance of parts (sections, paragraphs) in two-part form. Explains the modulatory scheme of the more developed types of binary form, and the means of integrating the whole composition.
