Whistling

I have been told that people only whistle or sing when they are happy. Is that true?

 Music Scholars refer to whistling as ‘momentary musical performing’. Other types of this form include drumming a beat on the desk or other object or even your thigh, humming while doing housework, and singing in the shower—which was found to have a calming and refreshing effect, soothing the nerves and elevating the spirits. Some people never whistle—often because they cannot. I loved to whistle as a girl but after I had my teeth straightened in adulthood, any ability to whistle disappeared. Interestingly, I met someone on one of my speaking tours abroad who said that he could not whistle as a boy, but when he got his teeth straightened, suddenly he could whistle! Go figure. There are not a lot of studies on whistling available. What has been shown is that more men than women whistle. More tomorrow.
