Yes, I realize that this is a space opera and not a twelve-bar blues. But trust me: this really does help.
(I thought it might be in the key of E, because that is, as we all know, the people's key. But no, it's E-flat. Which explains a lot; you can write space opera in sharps, but it's sort of awkward.)
(Perhaps I should have an icon for bits of self-recognized fruit-battitude.)
