Photo and balance

Once, I have read in a magazine about the composition technique.

The article says that dividing the canvas into 3 parts, or place one object as 1 third size.

I don't know why this makes the photo balanced, but it is certainly stable and very balanced composition, I thought.

Also, this is also important for art to place "blank" in the piece. Sometimes, we afraid that there is blank space, but this is very important not to place unnecessary things and keep necessary space.

The same thing is applied to the music. Silence makes the sound after silence stands out. As the gap becomes larger, the existing thing stands out more.

There are many things that seems to be trivial and unnecessary but potentially essential and important.
