In time, theory on the layout of the first movement became more and more focused on understanding the practice of Haydn, Mozart, and, later, Beethoven.
In the Classical period, the subdominant is the only possible substitute for the tonic at this position because any other key would need resolution and would have to be introduced as a false reprise in the developmentbut with the erosion of the distinction between the sharp and flat directions and the blurring of tonal areas true recapitulations beginning in other keys became possible after around But this is no more an essential element of sonata form than the introduction that may precede the main movement.
For instance in the first movement of Richard Strauss 's Symphony No. Thus, the initial part, which is repeated, leads directly into the second part by ending in the new key in which the second part begins.
A large-scale sonata movement often creates conflicts of key and theme that cannot be completely settled even by the full process of recapitulation. Such a scheme may have been constructed to conform with the programmatic nature of the movement, but also fits well with the Romantic penchant for beginning a work at maximum tension and decreasing the tension afterwards, so that the point of ultimate stability is not reached until the last possible moment.
Haydn in particular was fond of using the opening theme, often in a truncated or otherwise altered form, to announce the move to the dominant, as in the first movement of his Sonata Hob.
Expositions with more than two key areas[ edit ] Main article: In the theory of sonata form it is often asserted that other movements stand in relation to the sonata-allegro form, either, per Charles Rosen that they are really "sonata forms", plural—or as Edward T.
When they are less clear, greater importance is placed on varying the tempo during the course of the music to give "shape" to the music. In this richly ambiguous structure, the newly introduced motive would be regarded by the criterion of key, as the second subject; in purely thematic terms, it might almost be said to constitute the beginning of the codetta, or concluding section.

The partial recapitulations sometimes briefly recapitulate the second theme in the tonic key at the end of the first theme as a "false start", before the transition arrives, which then the transition leads to the actual second theme in the tonic before the closing section.
The first A section is called the "Exposition. Yet another is to introduce entirely new material. It represents a more open form than many of the earlier Baroque forms such as fugues, rondeau form, etc.
The Classical masters differ in their handling of this juncture. Haydn and Beethoven tend to celebrate its advent with panoply.
In the 20th century, emphasis moved from the study of themes and keys to how harmony changed through the course of a work and the importance of cadences and transitions in establishing a sense of "closeness" and "distance" in a sonata.
At this time, the term implies a binary form, usually AABB with some aspects of three part forms. Some composers, most notably Schubertcomposed sonata forms with three or more key areas. The Exposition states the main thematic elements and has its own internal form as follows:Sonata form (also sonata-allegro form or first movement form) is a large-scale musical structure used widely since the middle of the eighteenth century (the early classical period).
While it is typically used in the first movement of multi-movement pieces, it is sometimes used in subsequent movements as well—particularly the final movement.

Sonata-allegro form is a structural pattern used by composers first in the 18th century as a means to organize their music. Sonata form (also sonata-allegro form or first movement form) is a musical structure consisting of three main sections: an exposition, a development, and a recapitulation.
It has been used widely since the middle of the 18th century (the early Classical period). Although sonata form is sometimes called first-movement form, the first movements of multimovement works are not always in sonata form, nor does the form occur only in first movements. Likewise, the variant sonata-allegro form is misleading, for it need not be in a quick tempo such as allegro.
Sonata Allegro form was a development of the classical era. It represents a more open form than many of the earlier Baroque forms such as fugues, rondeau form, etc.
While there is a formula that can be applied, there was not a rigid, formal concept for the form. Sonata form, a Classical era invention used by Haydn, Mozart, and Beethoven, is a structural device often found in the first movement of multi-movement genres. Typically, a piece written in sonata.Download
