Puccalo is the term used for the highest level of human oral mouth whistling. The term is derived from combining the words "pucker" and "piccolo" and it refers to a level of skill and talent in human whistling which produces notes and tones that are so clear and precise, they remind the listener of someone playing a wind instrument. Playing the puccalo is distinguished from casual whistling, and places the instrument at the same prestige as other musical instruments.
