Lets discuss the act of producing musical sounds with the voice. AKA--SINGING.
One who sings is called a singer or vocalist.
As in many respects human song is a form of sustained speech, nearly anyone able to speak can also sing.
Oft times people dance while singing!
Singing can be formal or informal, arranged or improvised.
It may be done for pleasure, comfort, ritual, education, or profit. Excellence in singing requires time, dedication, instruction, and regular practice.
