Auto-Tune: Why Pop Music Sounds Perfect

If you haven’t been listening to pop radio in the past few months, you’ve missed the rise of two seemingly opposing trends. In a medium in which mediocre (平庸的) singing has never been a bar to entry, a lot of pop vocals suddenly sound great. Better than great: note- and pitch-perfect, as if there’s been an unspoken tightening of standards at record labels or an evolutionary leap in the development of vocal cords. At the other extreme are a few hip-hop singers who also hit their notes but with a precision so exaggerated that on first listen, their songs sound comically artificial, like a chorus of ’50s robots singing Motown.
The force behind both trends is an ingenious plug-in called Auto-Tune, a downloadable studio trick that can take a vocal and instantly nudge it onto the proper note or move it to the correct pitch. It’s like Photoshop for the human voice. Auto-Tune doesn’t make it possible for jus

Jazz is a mixture of music of Africa, the work songs the slaves sang, and religious music. Improvisation(即兴) is an important part of jazz. This is why a jazz song might sound a little different each time it is played.
Jazz bands formed in the late 1800s. They played in bars and clubs in many towns and cities of the South, especially New Orleans. New Orleans is an international seaport, and people from all over the world come to New Orleans to hear jazz.
Jazz became more and more popular. By the 1920s, jazz was popular all over the United States. By the 1940s, you could hear jazz not only in clubs and bars, but in concert hails as well. Today, people from all over the world play jazz. Jazz musicians from the United States, Asia, Africa, South America, and Eur

[单项选择]American culture has not been immune to cultural influences from outside. The idea of democracy came from the ancient Greeks: the Industrial Revolution started in England: jazz and rock music preserve African rhythms--to pick a few examples. Indeed, many of the things we think of as "100 percent American" came from other cultures.
Still, most of the changes in American culture over the last century have come from within, as the result of inventions and discoveries. And change has been dramatic. One hundred years ago the United States was largely a nation of farmers. Many of the things we take for granted today- a high school education, for example, or indoor plumbing—were luxuries then. The moon was a light for lovers, not a site for scientific exploration; genetic engineering (基因工程) was not even a subject for science fiction, much less for laboratory research and corporate investments. The decades following the Second World War, in particular, were characterized by spectacular sc
