Playing The Hairy Harmonica
To entertain by blowing the incredibly popular folk instrument that, characteristically, has two lip plates enclosing a long fipple, two holes - but only one ever fingered - and a wail switch. Skilled players use lip, tongue and mouth movements to create ecstatic music out of some lucky woman. (NB - in most countries you must be a least 16 years of age to play.)

"I have a young music student that has requested I show her how I go about 'playing the hairy harmonica'. Although I am a Professor of Music and expert flautist I am unfamiliar with this exact instrument. Can someone offer advice?"
"Yeah, bud - hold your breath in the wind section."
