2、tions attached to the passage. For questions 1-4, mark: Y (for YES) if the statement agrees with the information given in the passage; N (for NO) if the statement contradicts the information given in the passage; NG (for NOT GIVEN) if the information is not given in the passage. 2 Why Pop Music Soun

3、ds Perfect? If you havent been listening to pop radio in the past few months, youve missed the rise of two seemingly opposing trends. In a medium in which mediocre 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

4、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 chor

5、us 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. Its like Photoshop for the human voice. Auto-Tune doesnt make it poss

6、ible for just anyone to sing like a pro, but used as its creator intended, it can transform a wavering performance into something technically flawless. “Right now, if you listen to pop, everything is in perfect pitch, perfect time and perfect tune,“ says producer Rick Rubin. “Thats how ubiquitous Au

7、to-Tune is.“ Auto-Tunes inventor is a man named Andy Hildebrand, who worked for years interpreting seismic data for the oil industry. Using a mathematical formula called autocorrelation, Hildebrand would send sound waves into the ground and record their reflections, providing an accurate map of pote

8、ntial drill sites. Its a technique that saves oil companies lots of money and allowed Hildebrand to retire at 40. He was debating the next chapter of his life at a dinner party when a guest challenged him to invent a box that would allow her to sing in tune. After he tinkered with autocorrelation fo

9、r a few months, Auto-Tune was born in late 1996. Almost immediately, studio engineers adopted it as a trade secret to fix flubbed notes, saving them the expense and hassle of having to redo sessions. The first time common ears heard Auto-Tune was on the immensely irritating 1998 Cher hit “Believe.“

10、In the first verse, when Cher sings “I cant break through“ as though shes standing behind an electric fan, thats Auto-Tune-but its not the way Hildebrand meant it to be used. The programs retune speed, which adjusts the singers voice, can be set from zero to 400. “If you set it to 10, that means tha

11、t the output pitch will get halfway to the target pitch in 10 milliseconds,“ says Hildebrand. “But if you let that parameter go to zero, it finds the nearest note and changes the output pitch instantaneously“-eliminating the natural transition between notes and making the singer sound jumpy and auto

12、mat-ed. “I never figured anyone in their right mind would want to do that,“ he says. Like other trends spawned by Cher, the creative abuse of Auto-Tune quickly went out of fashion, although it continued to be an indispensable, if inaudible, part of the engineers toolbox. But in 2003, T-Pain (Faheem

13、Najm), a little-known rapper and singer, accidentally stumbled onto the Cher effect while Auto-Tuning some of his vocals. “It just worked for my voice,“ says T-Pain in his natural Tallahassee drawl. “And there wasnt anyone else doing it.“ Since his 2005 debut album, T-Pain has sent a dozen slightly

14、raunchy, mechanically cheery singles into the Top 10. He contributed to four nominated songs at Grammy Award 2009, and his influence is still spreading. When Kanye West was looking for an effect to match some heartbroken lyrics, he flew T-Pain to Hawaii to see how many ways they could tweak Auto-Tun

15、e. Diddy gave a percentage of his upcoming albums profits to T-Pain in exchange for some lessons. Even Prince is rumored to be experimenting with Auto-Tune on his new record. “I know Auto-Tunebetter than anyone,“ says T-Pain. “And even Im just figuring out all the ways you can use it to change the m

16、ood of a record.“ Rubin, whos produced artists as diverse as the Dixie Chicks and Metallica, worries that the safety net of Auto-Tune is making singers lazy. “Sometimes a singer will do lots of takes when theyre recording a song, and you really can hear the emotional difference when someone does a g

17、reat performance vs. an average one,“ says Rubin. “If youre pitch-correcting, you might not bother to make the effort. You might just get it done and put it through the machine so its all in tune.“ Rubin has taken to having an ethical conversation before each new recording session. “I encourage arti

18、sts to embrace a natural process,“ he says. With the exception of Milli Vanillis, pop listeners have always been fairly indulgent (纵容的 ) about performers ethics. Its hits that matter, and the average person listening to just one pop song on the radio will have a hard time hearing Auto-Tunes impact;

19、its effectively deceptive. But when track after track has perfect pitch, the songs are harder to differentiate from one another-which explains why pop is in a pretty serious lull at the moment. It also changes the way we hear unaffected voices. “The other day, someone was talking about how Aretha Fr

20、anklin at the Inauguration was a bit pitchy,“ says Anderson. “I said, Of course! She was singing! And that was a musician talking. People are getting used to hearing things dead on pitch, and its changed their expectations.“ Despite Randy Jacksons stock American Idol critique-“A little pitchy, dawg“

21、-many beloved songs are actually off-pitch or out of tune. Theres Ringo Starr on “With a Little Help from My Friends,“ of course, and just about every blues song slides into notes as opposed to hitting them dead on. Even Norah Jones, the poster girl of pure vocals, isnt perfect. “Theres some wonderf

22、ul imperfections of pitch on Dont Know Why from Come Away with Me,“ says Anderson, “and most of the other tunes on the album as well. But I wouldnt want to change a single note.“ Lets hope that pops fetish for uniform perfect pitch will fade, even if the spread of Auto-Tune shows no signs of slowing

23、. A $99 version for home musicians was released in November 2007, and T-Pain and Auto-Tunes parent company are finishing work on an iPhone app. “Its gonna be real cool,“ says T-Pain. “Basically, you can add Auto-Tune to your voice and send it to your friends and put it on the Web. Youll be able to s

24、ound just like me.“ Asked if that might render him no longer unique, T-Pain laughs: “Im not too worried. I got lots of tricks you aint seen yet. Its everybody else that needs to step up their game.“ 2 Which of the following is described as a “Photoshop for the human voice“? ( A) Vocal cords. ( B) Hi
