Hinge technique
The hinge technique, defined in richards-2016 (par.49), is a technique used to create a developing idea.
It is used in approximately 25% of developing themes in film music (richards-2016 par.49).
The gist is that you use the second half of your first basic idea to start the first half of your second basic idea.
Examples
Star Wars: Main Theme
The quintessential example (in my opinion) is the main theme to Star Wars.

Legend of Zelda Main Theme
