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 to do-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!

答案与题解：

1.A　第一段的第一句：作曲家大卫?科普编写了一个计算机软件，它能创作出古典音乐作品。

2.C　从第二段的第一句可以看出，大卫编写电脑软件的目的是写歌剧。A、B和D都属于创作歌剧的一部分。

3.D　第二段的后半部分讲的是伟大的歌剧作者与一般的歌剧作者的不同之处是通过对数据进行准确的构建、记忆而后创作出新的音乐形式。

4.B　从第五段第一句可知艾米是计算机软件。

5.D　从本文第一句可知大卫是一个作曲家，不是计算机程序员，所以排除A，B和C项内容没有提及;从本文的第五段和第六段可知，艾米大大提高了大卫的创作速度，最后一句，大部分重活都由艾米来做，所以作曲家只干一小部分工作。
