Sonata Allegro Form

The roots of this form of sonata allegroform can go back to the Baroque era of simple binary format. Using binary, these two parts are similar in theme to the theme and texture identity throughout the motion. The term "sonata" originally refers to musical instrument music and does not refer to a specific form of composition. Baroque sonatas can be traced back to the instrument called Kanson da sonar in the late Renaissance era. Its name has four instruments consisting of two melody instruments, a chord musical instruments and bass continuous music, which eventually lead to the trio sonata.

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.

An important variant of the traditional sonata - soprano shape can be found in the first move of a classical concerto. Here, the habitual "repeat explanation" of Sonata - soprano is replaced by two different but related parts, namely "tutti elaboration" and "solo exposition". In the prototype, "Tutti elaboration" is not a soloist (except in the early classics, "continuous" character), it does not contain a deterministic sonata of the secondary key - explain the modulation. Solo instruments only claim to be involved in the transition to (classical) or relative professionalism only when the solo exposition is in progress. Beethoven Piano Concerto No. 4 and No. 5 in the late classical situation seems to be different from the beginning to the soloist's voice. Since the late stages of these movements are clear, the open piano solo or early piano is actually popular before the fair's start.

The first move is Sonata - Allegro and G major - it then consists of three main parts: Expo in two themes, development with many keys, reproduction and coder. The first theme of Sonata - Soprano starts with a comfortable, slightly radical, enhanced theme with similar repetitive wording. There is a short transition paragraph that matches the second topic. In contrast, the second theme is elegance and not so hurried. The second theme is not the main major G major but the main D major. The entire exposition is repeated and there is a short transition to development
