How to Get the Song of Passing

Go to the top of the cliff on Windfall Island near the bomb shop.You will see a dancing fellow, named Tott, dressed somewhat like Elvis.

Show him your Wind Waker?(or have it out close to by him) and allow it to chime a 3/4 tune on its own and it will trigger a conversation. Tott will motion a song to you through his dancing. This isn't required to finish the game, but very helpful in the mainquest as well as sidequests (accessing Ghost Ships for example). Play this song: right, left, down. You will now be able to use the?Song of Passing?to switch from day to night and vice versa.
