Breath control

Control Of Breath:
This is also a very important step towards voice culture. If we can master our breath, we can easily master our voice for singing. Breath Control gives fine-ness, clarity, steadiness and confident phonation to the voice. There are 4 types of breathing: Clavicular (shoulder), Costal (chest), Diaphragmatic and Abdominal. Clavicular breathing is useful to sing very shrill notes. Costal breathing is used to high-pitched notes. Diaphragmatic breathing is useful for every singer. When a singer cultivates this type of breathing, unnecessary and unwanted wobbling or shaking of voice can be controlled. Abdominal breathing helps to sing the lower notes effectively.

music fans are more than welcome to read the full article. I have quoted since it is informative as well as lucid. I could not have explained it better myself.
