The classical sonata form began in the classical era and the sonata form was the foundation of most instrument music. The sonata form became a clear structure of the movement of the first instrumental work. This form consists of three parts: exhibition, development and reproduction. If you have studied something about the format of the story, its purpose is the same, so I know a lot about the Sonata format. The trade fair (the same word for music and literature) sets the scene.
The first movement of Pathtique is shaped like a classic sonata, but its material is quite different from the traditional sonata shape. That is the symphony and the common one is the introduction later than anything else. The dotted rhythm reminds me of the style of French overture. In this movement, tragic emotions are exacerbated by discordant chords, sudden changes in dynamics and records, and expectations. A slow introduction was incorporated into Allegro and continued in an imaginative and dramatic way (Kamien, 2004).
Since its foundation, the Sonata form has become the most common form of long classical music such as Symphony, Concerto and String Quartet, as well as the first work called Sonata. Therefore, there are many theories about what the practice of unifying and distinguishing the shapes of sonatas is in both the era and the era. Even works that do not conform to the standard description of the sonata format often have a similar structure and can be analyzed as a detailed description or extension of the standard description of the sonata form.
In sonata style theory, other movements are related to the sonata - soprano format, or according to Charles Rosen, they are actually something like "sonata form", plural form, or Edward T. Cone's claim Sonata - Allegro is ideal for other sports facilities that "admire". This is particularly true for other forms of exercise that appear as sonatas, especially in works. As a sign of this situation, the word "sonata" is sometimes attached to the name of the form, especially in the case of the "sonata - Rondo" form. In particular, slow motion is thought to be similar to the sonata - soprano format, but the grammar is different, development is not much emphasized.
