第二十九篇：I'll Be Bach

Composer David Cope is the inventor of a computer program that writes original works of classical music. It took Cope 30 years to develop the software. Now most people can't tell the difference between music by the famous German composer J. S. Bach (1685-1750) and the Bach-like compositions from Cope's computer.

It all started in 1980 in the United States, when Cope was trying to write an opera. He was having trouble thinking of new melodies, so he wrote a computer program to create the melodies. At first this music was not easy to listen to. What did Cope do? He began to rethink how human beings compose music. He realized that composers' brains work like big databases. First, they take in all the music that they have ever heard. Then they take out the music that they dislike. Finally, they make

new music from what is left. According to Cope, only the great composers are able to create the database accurately, remember it, and form new musical patterns from it.

Cope built a huge database of existing music. He began with hundreds of works by Bach. The software analyzed the data: it broke it down into smaller pieces and looked for patterns. It then combined the pieces into new patterns; Before long,the program could compose short Bach-like works. They weren't good, but it was a start.

Cope knew he had more work todo-he had a whole opera to write. He continued to improve the software. Soon it could analyze more. complex music. He also added many other composers, including his own work, to the database.,

A few years later, Cope's computer program, called "Emmy", was ready to help him with his opera. The process required a lot of collaboration between the composer and Emmy. Cope listened to the computer's musical ideas and used the ones that he liked. With Emmy, the opera took only two weeks to finish. It was called Cradle Falling, and it was a great success! Cope received some of the best reviews of his career, but no one knew exactly how he had composed the work.

Since that first opera, Emmy has written thousands of compositions. Cope still gives Emmy feedback on what he likes and doesn't like of her music ,but she is doing most of the hard work of composing these days!

答案與題解：

1.A第一段的第一句：David Cope發(fā)明了一個可以編寫出古典音樂的電腦軟件。

2.c從第二段的第一句可以看出，David編寫電腦軟件的目的是寫歌劇。A、B和D都屬于創(chuàng)作歌劇的一部分。

3.D第二段的后半部分講的是偉大的歌劇作者與一般的歌劇作者的不同之處是通過對數據進行準確的構建、記憶而后創(chuàng)作出新的音樂形式。

4.B從第五段第一句可知Emmy是一計算機軟件。 ’

5.D從本文第一句可知David是一個作曲家，不是計算機程序員，所以排除A;B、C內容沒有提及;從本文的第五段和第六段可知，Emmy大大提高了David的創(chuàng)作速度，最后一句，大部分困難的工作都由Emmy來做，所以作曲家只干一小部分工作。
