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 analyzemore 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 ofcollaboration 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’tlike of her music, but she is doing most of the hard work of composing these days!

Until recently, the industry has had little guidance in how to proceed with development without harming wildlife. Regulations are mostly imposed by states or local authorities, whose patchwork guidelines vary from stringent to lax. The Wind Turbine Guidelines Advisory Committee, established in 2007 under the U. S. Fish and Wildlife Service, is proposing federal recommendations to reduce wind development’s effect on wildlife. Composed of wind-industry members, wildlife officials, and federal authorities, the committee will present the recommendations to the secretary of the interior for review in October. The recommendations are voluntary, but according to David Stout of the U. S. Fish and Wildlife Service, the guidelines will be" unprecedented in terms of companies agreeing to hold themselves to a higher standard."
The Wind Turbine Guidelines Advisory Committee is composed of all the following EXCEPT

A:wind-industry members. B:wildlife officials. C:federal authorities. D:David Stout.
