The human voice can produce a variety of sounds, depending on the vocal cords and the surrounding environment. These sounds range from normal speech to various forms of singing. Within singing, there are different vocal ranges that each produce unique sounds. One such vocal range is falsetto, which is produced by pushing air up through the throat and nasal cavities instead of using the diaphragm and lungs. This results in a higher-pitched sound that is usually used for purposes such as melodic lines or ornamentation.
