Meaning of Exposition in Music
In music, the term "exposition" refers to the initial presentation of the thematic material in a musical composition, movement, or section. It is a fundamental part of various musical forms, such as fugue and sonata form ).
In a fugue, the exposition is one of the main sections. It typically consists of each voice playing its own adaptation of the theme, known as the subject or answer. The voices also provide countersubjects (counterpoints) to the following voices as they enter. The exposition usually ends on either a I or V chord and is followed by the body of the fugue ).
In sonata form, the exposition is the first part of the movement. It introduces one or more themes, with the first theme often being forceful in character and presented in the tonic key. The second theme is usually in a contrasting key. The exposition sets the stage for the development and recapitulation sections that follow.
Overall, the exposition in music serves as the initial presentation of the thematic material, setting the foundation for further development and variation throughout the composition ).
In sonata form, the exposition is the first statement of the theme; it is the first of the three major sections in sonata form. Usually there are two major theme groups in the exposition, possibly followed by a codetta. The exposition is followed by the development, in which the themes presented in the exposition are expanded, reshaped, and manipulated. Finally the same themes are presented in very nearly their original form in the recapitulation, which is the last section of the sonata form.
