Have you seen these melody maps cropping up everywhere? I would link to some, but as this an 11th hour activity (literally - it is 11 o clock in my area of the world - yes on SATURDAY NIGHT!), you'll just have to imagine with me.

Is it perfect? Absolutely not! Does it probably need work? Definitely! Aren't you so glad that google docs are editable? I know I sure am!
