You will learn the very subtle head turn animation, or what is called a "take". This is what animators mean by a character's reaction to something that get's their attention. You will learn that a "take" can be accomplished in many ways. This is the most simple form.
Why Is This Important?
The speed and motion of the eyes moving across the face simulate a head turn. The head actually doesn't turn, but the eyes draw closer together as they travel across the face. This slight bit of perspective convinces the audience that the character is looking to our left. Don't let the simplicity of this exercise fool you. It is a very elegant little gem. And we will build upon it in future recipes.
