setting the tone

i read this in family circle magazine and thought it was neat.

"Researchers at the University of California, San Diego, found a strong link between speaking a tonal language (such as Mandarin, a form o Chinese), in which the meaning of a word changes depending on the tone, and having perfect pitch (the ability to produce a specific musical note without hearing a reference note). Fewer than 1 in 10,000 Americans and Europeans possesses perfect pitch. They found that 60 percent of Mandarin-speaking students who started music lessons by age 5 demonstrated perfect pitch, compared to 14 percent of English language speakers."

As a side note, Celine Dion & Barbara Streisand both have perfect pitch.
