==Form==

Form refers to the structural aspects of a piece of music. Usually, the analyst assigns a letter to each distinct section. Basic examples of form include binary form (A B), in which one section is followed by a contrasting section, or ternary form (A B A), in which the first section returns, usually in slightly altered form, to give a sense of formal closure.

Basic examples of form include binary form (A B), in which one section is followed by a contrasting section, or ternary form (A B A), in which the first section returns, usually in slightly altered form, to give a sense of formal closure. The typical form of a popular song might be written as AABABCBB, where A is the verse, B is the chorus, and C is the bridge. One commonly used form in the classical periods is [[Sonata form]], which is a specialised, elaborate ABA form. Sonata form, in classical music, is typically used as the first movement in most large-scale instrumental works such as symphonies and concertos. Another commonly used form is rondo form, in which a recurring section is contrasted with successive new sections, as in ABACADAEA. It is often used in the final movement.
