Answer:
1. an elaborate musical composition for full orchestra, typically in four movements, at least one of which is traditionally in sonata form.
2. a composition for an instrumental soloist, often with a piano accompaniment, typically in several movements with one or more in sonata form.
3. the concluding passage of a piece or movement, typically forming an addition to the basic structure.
4. exposition, development, and recapitulation
4a. exposition- the initial presentation of the thematic material of a musical composition, movement, or section. The use of the term generally implies that the material will be developed or varied.
4b. development- musical development is a process by which a musical idea is communicated in the course of a composition. ... In sonata form, the middle section (between the exposition and the recapitulation) is called the development. Typically, in this section, material from the exposition section is developed.
4c. he recapitulation is one of the sections of a movement written in sonata form. The recapitulation occurs after the movement's development section, and typically presents once more the musical themes from the movement's exposition.
there's the first 4 answered :)
