Our world is filled with things that can be found in groups of four. Some things that may come to mind include the tires on a vehicle, a singing quartet and four quarters to a whole. However, there are many things that are considered an oversight when it comes to this grouping. Let's explore some examples.

Four quarter notes or their equivalent are arranged to fit within a margin of music. A margin has four beats.

The babies born in these groups of four do experience low birth weights. All reported quadruplet births were premature. However, with advancements in medicine their survival rate has significantly increased over the past few decades.
