was any part of your score already pre-written other than the jingles? or are you making it up right now as you go?
only certain prominent things were written, and only in places where nothing is spoken, like for example, in places where the music IS the script.  like  "*DING* ... oh look my popcorn is done" i prefer to actually choose what note the ding is when i'm writing the script. this line is not in the video, but this is just to give an example of what kind of score items get writing treatment along with the script. everything else that's generally under the narration is not composed until the actual score process
