The recapitulation.
A sonata is a three-movement piece for solo piano or any solo instrument with or without piano accompaniment. Sonata-allegro refers to a particular form originally used in one-movement pieces, later incorporated in the three-movement sonata which was named for the form. A typical sonata-allegro form is I first theme, expansion II second theme, expansion III development of the opening theme or themes IV recapitulation of the themes V coda Sonata-allegro originally included tonal relationships between the first and second themes, tonal freedom during the development, and tonal unity of the recapitulation and coda.
recapitulation: emergence during embryonic development of various characters or structures that appeared during the evolutionary history of the strain or species; (music) the section of a composition or movement (especially in sonata form) in which musical themes that were introduced earlier are repeated; a summary at the end that repeats the substance of a longer discussion; (music) the repetition of themes introduced earlier (especially when one is composing the final part of a movement)
Many compositions feature a single movement in sonata form, but one notable example is Beethoven's "Piano Sonata No. 14 in C-sharp minor, Op. 27, No. 2," commonly known as the "Moonlight Sonata." The first movement of this sonata exemplifies the sonata form, consisting of an exposition, development, and recapitulation. This structure allows for a rich exploration of themes within a cohesive framework. Other examples include various concertos and symphonic movements that adopt a similar single-movement sonata form approach.
Coda Coda rounds off a movement by repeating themes or developing them further. it always ends in tonic key.
Bert. Rondo or Rondó means "round". This movement is a "circle" that has different themes (and their developments).
"Ode to Joy" is a theme from the last movement from Beethoven's Choral Symphony (Opus 125). It is first introduced by strings after the themes from the previous movements were restated. Then it recurs throughout the movement between strings and chorus.
the conflict of tonalities between the first and second themes.
In most sonatas, there are two themes that occur, the first and second subject. These are played and sometimes repeated. Following that there is a section of developement, in which both themes are changed and fused in various ways. Following that is the recapitulation, where the themes are repeated, often with minor variation. A perfect example of this kind of sonata is Schubert's Unfinished symphony, mvt 1. This said, smaller chamber music sonatas have been known to only have one subject, and romantic music sucha as that of Dvorak often had three or more subjects.
development of themes
A bridge is not a recognized part of Sonata-Allegro form. In the classical symphony the elements are, 1. Exposition, sometimes preceded by an introduction. A first theme in the tonic key of the symphony is followed by a second theme in the dominant key. The exposition is usually repeated. 2. Development, one or both themes are varied and expanded through several keys. 3. Recapitulation, the exposition is repeated, but both themes are now in the tonic key. 4. Coda, a short section which closes the movement.
1. A tonal plan that involves a) establishing a main tonality, b) building up tension by introducing one or more new tonalities, c) dissolving this tension by bringing the music back to and concluding it in its original tonality. a) and b) constitute the first part of the sonata movement, c) the second. 2. A sonata movement often opens with a bold statement of a theme, melody, or group of distinct motives, which help to establish the original tonality. New tonalities, then, get often marked by the introduction of new, and often contrasting, themes. The process of dissolution of tonal tension, accordingly, can be "staged" by the composer as a conflict and reconciliation between themes. The underlying process, however, is about tonalities.
It depends.For instance, a sonata allegro movement may be set up like this: Introduction, First Theme, Second Theme (in a contrasting key), repeat of the First and Second Theme (the first statements of these themes are called the Exposition), then the Development, then repeat of the Exposition in the key of the First Theme and then Coda.A sonata allegro movement may be set up differently, though, with more themes, with two Expositions or twoDevelopments etc.And of course there are other kinds of movements besides sonataallegro!Often sonatas have three or four movements but there are some that have more or fewer. It depends on what the composer needs to develop the basic material of the music and how this will be done over time for clarity or emotional effect.
