In the key of E major this song is all about moving into and claiming life. Yes I Can sings with the active melody of the intro. The arpeggiation accents the action forward into grasping what life is laying out before us. The melody is a repeating shape that says come on, like a hand beckoning. When the oboe starts, the warmth of acceptance is felt, repeating the delightful dance that now is in rhythm. The key is power and will and decision. One must take the steps. The song is the invitation.
