As part of my pre production planning, I wrote out the lyrics to my song and matched the timing with what visuals I would want to film at that time.
The time is the time that the certain lyrics recorded finish.
The language is informal and slang like because they are rough notes and I had to note them down quickly with the pace of the music.
When filming, this document has proven to be very useful as I have already planned what I want the actress to do/sing etc which has saved time but I can change and edit this as I go along and film different sections if things don't work out, it is just a rough plan of my ideas.
