Introduction
- Slow and stately, Commanding, Catches your attention
- Varying lengths
- Not always present
- This section introduces the main themes of the piece
- The first theme is usually grand, and the second contrasting, and usually lyrical
- The first theme is in the tonic key and the second theme is usually in the dominant
- The entire exposition is usually repeated
- One or more of the themes are played around with and changed up
- The development often ends with something called a retransition - that part that feels quite intense and builds up, usually with new material or transition material to bring us back to the main theme.
- This is when the two themes from the exposition return in their original form
- The second theme though is usually in the tonic key
- Though the piece may end with the recapitulation, many sonata-allegro form pieces have a coda
- A "tail" end - with a grander variation on one of the themes, a piece of the development, new material or very grand sounding final material
