Finally, though introductory material may be referenced later in the sonata, the introductory module only occurs once in a standard sonata movement (unlike a pop/rock introduction). Thus, even without repeats in a score or a performance, once the thematic cycle of the exposition, development, and recapitulation has been identified, the introduction can be identified as music that precedes the first occurrence of that cycle.

Because the introduction is not part of the exposition, it is not repeated in the recapitulation. Thus, a composer’s open repeat sign ||: in the score can be an important visual clue in identifying the end of an introduction and the beginning of an exposition. If the exposition is repeated, the introduction is not repeated with it. IntroductionĪn introduction is any material that precedes the primary theme zone (P). Some common characteristics of these modules are provided below, many of which are shared with introductions and codas in pop/rock music.

These help to “frame” the big picture, and to create a coherent musical narrative - often an arc that builds in tension to a climax and resolves to a point of relative rest by the end of the movement. Larger sonata movements tend to have one or more framing modules: either an introduction, a coda, or both. Of course, sonata-form movements typically have other narratives to tell musically, and the bigger the story, the more care composers take to hold it all together. The grammar of a sonata - the basic harmonic and thematic story that anchors the formal style - is accomplished largely in the exposition, development, and especially the recapitulation.
