How do people sing?

Question:

How do people sing?

Why can some people sing and others can't? Is it the shape of the vocal cords etc.? Silly question...I know, but just a passing thought.

Best Answer - Chosen by Asker: There are many different reasons why. Some people have different accents and some people are from many different places in the world. It also depends on how long they can hold their breath, how they sound and how their vocal cords are shapes, lubricated and placed. It also depends on if you have a high or low sound or if your voice cracks alot.
