Everyone has the ability to sing. Some people naturally have better voices than others, but anyone can become a good singer simply by learning to hear and identify sounds and then practicing them.
The sound which we know as singing is made by air from an exhaled breath (breathing out) passing over the vocal cords, and causing them to vibrate. The vocal cords are small muscular folds of skin located inside the larynx (commonly known as the "voice box").
The sound is then amplified (made louder) and modified by the resonance spaces in the mouth and throat and behind the nose. The sound may also be altered by the shape of the mouth, the lips and movements of the tongue as the sound leaves the mouth.
Because everybody’s anatomy is slightly different, each voice will have its own individual sound both when speaking and singing. The following diagram shows all of the parts of the body which are involved in creating the first sound of a singing note. A singing breath usually starts with the diaphragm muscle and then travels upward from there.
