The satisfying thump of a bass drum sounds every
time Gil Weinberg strikes thin air with his iPhone. A pal nearby swings his
Nokia smartphone back and forth, adding a rippling bass line. A third
phone-waving friend sprinkles piano and guitar phrases on top.
Weinberg's trio are using software that turns ordinary cellphones into musical
instruments. "People can play on their own, but we are more excited about
them jamming like a band," says Weinberg, a music technologist at the Georgia
Institute of Technology in Atlanta. Commuters regularly bombarded with tinny
recorded music played on other passengers' phones might not share his
enthusiasm, but air guitarists and would-be drummers will probably be delighted.
Weinberg claims his smart gesture-recognition software will democratize
music-making as never before. "With the fight tools, everyone can be creative
and expressive musically-even if they don't know anything about music theory,"
he says. The software, dubbed ZoozBeats and launched this week,
monitors a phone's motion and plays a corresponding sound. For example, you
might play a rhythm based on a snare drum by beating the air with the phone as
if it's a drumstick. Or you could strum with it to play a sequence of guitar
chords. The software runs on a wide range of phones because it uses many
different ways to sense gestures. The obvious way is to use the accelerometers
built into small devices like the Apple iPhone and Nokia N96 smartphone. But
ZoozBeats can also trigger sounds when the view through a phone's camera lens
changes rapidly, or generate a beat or bass line from simple taps on the
mobile's microphone. Of course, people who aren't well skillful
in music-making are more likely to make unpleasant noises than beautiful
melodies, so ZoozBeats incorporates a system called Musical Wizard to make sure
their musical decisions are harmonious. It won't do everything, though. The
system has been built to ensure that practice still makes perfect: "The
big challenge was not to make it sound OK whatever you do," says Weinberg. "It
will fit, but not perfectly, so you can still learn to improve the music
yourself." ZoozBeats comes with instruments for three types of
music: rock, techno (a form of modern electronic music with a very fast beat)
and hip hop. It also allows users to produce vocal effects by singing into the
phone and will be downloadable in two versions. One of these will be for solo
use, the other a Bluetootb networkable version that supports jamming by groups
of people-using the Musical Wizard to keep everybody's input melodious.
单选题
Some commuters might not be delighted in others' cellphone music in
that
A. they are not interested in the tinny recorded music.
B. they are not identified with the music made by the software.
C. they are fed up with the music played on the cellphones.
D. they are more interested in jamming like a band.
【正确答案】
C
【答案解析】事实细节题。考查因果细节，根据commuters定位到第二段。其中讲到通勤者每天都受到其他乘客手机里录制的尖细音乐的狂轰滥炸(bombarded with)，故可推断他们可能不高兴的原因应为C项。A项“他们对尖细的录制音乐没有兴趣”、B项“他们不认同软件创作出的音乐”未在原文提及：D项的jamming like a band是文中Weinberg所希望看到的，属于张冠李戴。
