第二十九篇： Ill Be Bach Composer David Cope(第1题关键词) is the inventor of a computer program that writes original works of classical music(第1题答案出处). It took Cope 30 years to develop the software. Now most people cant tell the difference区别 between music by the famous 著名的German composer作曲家 J. S. Bach (1685--1750) and the Bach-like类似巴赫 compositions作品, from Copes computer. 作曲家大卫 · 科普发明了一个计算机软件，它能编写出古典音乐的原创作品。科普花了 30 年才完成这个软件。现在，科普的计算机写出的作品与德国著名作曲家 J . S．巴赫写的作品很相似，很少有人能分辨出其中的不同。 　　It all started in 1980 in the United States, when Cope(第2题关键词) was trying to write an opera(第2题答案出处). He was having trouble thinking of new melodies, so he wrote a computer program 程序to create the melodies旋律. 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(第3题关键词) are able to create the database accurately, remember it, and form new musical patterns 模式from it. (第3题答案出处) 这一切始于 1980 年的美国，那时科普正在写一部歌剧，但是他无法创作出新的旋律，于是他编写了一个计算机软件来帮他编曲。最开始的时候，软件写出的乐曲并不动听。科普是怎么做的呢？他开始重新考虑人们作曲的方式。他想到作曲家的大脑就像一个大数据库，他们先是吸收他们听过的所有音乐，然后去除他们不喜欢的，最后再根据留下的音乐来创作出新的旋律。科普认为，只有伟大的作曲家才能建立好的数据库，并且能熟记于心，从而创作出新的音乐。 　　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 werent good, but it was a start. 科普根据现有的音乐建立了庞大的数据库。最开始的时候，数据库包含了几百部巴赫的作品。科普的软件将这些数据进行分析：首先它将音乐拆解成小的片段，从中找出固定模式，然后将片段组合成新的模式。不久，这个软件就能够写出和巴赫风格很像的小曲子。它们并不完美，但这只是个开始。 　　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
