How do composers transition between sections of songs?

Now that we understand how developmental material works, we can look at how it can be used to transition between formal sections in a piece of music. The hallmark of developmental and transitional material is the Sonata-Allegro form. A deep dive into this form is beyond the scope of this course, for now, it’s best to think of it as an extended rounded binary form. Let’s look at the first movement of Mozart’s Sonata in C to get a better idea of transitioning between sections of music.

In this work, Mozart’s primary method of transition is through sequencing of scale and arpeggio patterns. An important lesson that can be taken from this piece is that a simple set of melodies can be expanded into a longer work through repetition and sequencing!
