Singaporean singer Stefanie Sun has become a trending topic on Chinese social media platforms once again. This time, it is not for a new album or concert, but for     1     artificial intelligence version of her voice.

In recent weeks, a series of music videos     2     (feature) Sun’s “voice” have created a buzz. It is incredible that none of the songs are sung by Sun herself.     3    , they are produced by AI software. One of them, a video of Fa Ru Xue, whose original singer is Jay Chou,     4     (view) more than 1.6 million times since it was posted on April 14.

Many viewers embraced a technology that provides people with a different way     5     (enjoy) their favorite music.

8 . Is there a friend of yours who always sings out of tune (曲调) but never realizes it? Don’t be so hard on them — they may have amusia — the inability to tell the difference in tunes.

Apart from singing out of tune, people with amusia may also find it hard to recognize music they’ve heard before without the help of song lyrics. Besides, people who suffer from Amusia can have difficulty in recognizing melodies and a total inability to tell between different musical sounds, according to Live Science. However, people with amusia can recognize common environmental sounds as well as the high and lows sounds in human voices, meaning that this inability can be specially related to music.

In many cases, people who have amusia are born with it, as 46 percent of these individuals’ family members were found to have similar conditions, according to a 2017 study. Brain imaging shows that their brains receive and respond to music pitch (音高) information, but it is not reaching conscious awareness, meaning that the mind can’t understand the information.

Scientists at the University of Otago in New Zealand also think that amusia is related to people’s special processing skills. They invited people with amusia, musicians and students from non-musical backgrounds to perform a task related to spacial imagination. They were asked to decide whether pairs of images are the same object moving around or mirror images.

The result showed that the amusia group made more mistakes than the other two groups. Amusia might be related to the way brain stores information about the high and low sounds in songs, according to the study.

Although those who aren’t confident about their singing skills often say they’re “tune-deaf”, people with amusia only make up about 1.5 percent of the population, as shown in the 2017 study. “Like dyslexics (诵读困难者) can learn how to read, those with amusia should be able to better their ability to recognize tunes if they start early enough,” Isabelle Peretz, a professor of psychology from the University of Montreal in Canada, told Live Science.

10 . To Their Own Beat

When Los Lobos perform in concert today, audiences in the thousands cheer them on. It’s hard to believe that the group started out as just another garage band playing popular rock-and-roll tunes from the radio, In 1974 four high school friends from East Los Angeles formed Los Lobos ( Spanish for “The Wolves” ) .

Like many garage bands, these friends might have simply gone their separate ways after high school. But the members of Los Lobos wanted to keep making music together. They decided to change their musical style and began focusing on traditional Mexican music that showed their tradition.

“We pulled out all those records we used to beg our parents not to play around our friends and found an incredible wealth of music,” says Perez. “These guys (on the records) were doing amazing things with their instruments, and we started trying to pick up on it. ”

The group put aside its electric guitars for the acoustic ones used in traditional Mexican music. For several years Los Lobos played at weddings or parties—any event that needed live music. They also landed a regular engagement (合同)   at a Mexican restaurant.

By 1978 Los Lobos had made enough money to record their first album   (唱片) , and they sold copies of it wherever they performed. They also returned to their electric guitars to get closer to a Tex-Mex sound, which is a mixture of traditional Mexican music, rock and roll, country music, and the blues. This new, louder sound produced one unexpected result: the group was fired from the restaurant.

But it didn’t matter that Los Lobos had lost their one steady job, because they had found a position that no other group took up. They had combined electric and acoustic instruments and blended (混合) musical styles in their own way. Steve Berlin joined the band in 1983 as the saxophone and keyboard player, adding to the band’s unusual sound.

“We didn’t so much want to recycle the music we’d grown up with as much as find the common links between it and all the other styles and sounds that were all around us,” Perez explains.   “It became a mission ...   bringing music together to bring people together. ”

In the 1980s Los Lobos gained the attention of several record companies. They were hired to perform on the soundtrack to the film La Bamba, which earned them a Golden Eagle Award. They have since earned many awards, including two Grammys and an MTV Video Music Award. Their many records have been very successful, and they have toured the world.

Even after 30 years of making music together, Los Lobos continues to experiment with their sound. They never moved far away from their Mexican roots, however.   They still include traditional music in their live performances, sharing their history—and their culture—with their fans.
