Singing is the production of musical tones by means of the human voice.
In its physical aspect, singing has a well-defined technique that
depends on the use of the lungs, which act as an air supply, or bellows;
on the larynx, which acts as a reed or vibrator; on the chest and head
cavities, which have the function of an amplifier, as the tube in a wind
instrument; and on the tongue, which together with the palate, teeth,
and lips articulate and impose consonants and vowels on the amplified
sound.
