Sonata Allegro

Sonata Allegroform is a development of the classical era. Fuga, Rondo form etc, it is an open form than the initial Baroque style. There are applicable expressions, but the format has no strict and formal concept. Instead, it developed into a classical era and beyond. Haydn is one of the initial representatives of this form. It was named "Sonata Allegro". The last Allegro exercise in Sonata was mostly created in this format. However, it is by no means limited to this general rule.

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.
