I've been playing with lyricism.
Bernie Taupin.... You know him? He wrote, for example, "Philadelphia Freedom". Ahhhh.... but you thought Sir Elton John wrote that melody. And you are exactly right. Elton wrote the melody, but hid DID NOT write Philadelphia Freedom. Nope, the words... those were Taupin's. Yes, you can call it poetry. But while all lyrics are poetic, not all poetry is lyrical. Lyrics rhyme. They are percussive, and their timing slides within the melodic discipline.
So, how to do an establishing shot that is lyrical? That sets up the melody to come and with color, texture, and an array of elements the provide the coming story arc with everything it needs? Hmmmm.... What better place than Cannery Row to set the scene? And how to mix mystery, with portending (great word huh?), and sufficient ambiguity that the viewer begins creating the melody? Lyrical... get it?
