Theme

Being that I am not writing the entire script for this musical, mainly because I only ever plan on filming the opening number, I figured I needed a theme to help give it some sort of purpose. I've spent a lot of time listening to opening songs from a number of musicals (is it weird that I have 17 musicals or quasi-musicals on my iphone) and there seems to be a few universal building blocks that are required. Beyond introduce the characters, it seems the main purpose of any of these songs is to establish the theme for the rest of the show. Occasionally extends to the point of bludgeoning you with it. Hopefully I will not have to take it that far, or maybe I will. Who knows?
Being that the setting for this musical is the subway and surrounding areas, the idea of transportation, or a journey, is the obvious place to start. With that and mind I have decided on a two pronged theme. The literal form of, "the journey is half of the adventure, not just a means to an end" and the more metaphorical needing to not live only looking to the future but to live in the here and now. These ideas will be used to shape the characters, their back-stories and their motivations.
As always, comments are appreciated
