Many Chinese people like American country music (乡村音乐), such as the songs of John Denver. But still some people don't know when country music began.

Country music is from the folk music (民间音乐) of the Appalachian Mountains in the east of America. There, people sang while playing the violin and guitar. They sang about everyday life, love and their problems. So the songs were sometimes a little sad.

One of the most popular country music singers is John Denver, who is also quite famous to the Chinese. For Denver, music was a language that could bring the world together. He says music can bring people together. We will understand each other better through music. People are different in color and they may speak different languages, but people are the same in mind and body. All of them who love music can understand music.

The world lost a great man when John Denver died in 1997. But his music and words will live on.

Erhu is a kind of traditional Chinese musical instrument. There are many English names for erhu as urheen and urhien. When I listened to the sound of erhu, I fell in love with the instrument.

I was born in a traditional Chinese family. My grandfather is a fan of Peking Opera and erhu music. When I was very young, my grandpa often sang Peking Opera as he played erhu. Sometimes the melody was exciting, sometimes sad. I was attracted by the sound of erhu.

At the age of eight, I decided to learn to play erhu. At the beginning, I had great interest in playing it. But I found it difficult to play it soon. I wanted to give up. My grandfather encouraged me to hold on. Up till now I have been playing erhu for six years. I have already passed Level 9. I even got the first prize in the instrument competition. Now I feel so proud that I can play erhu well.

American band “The Backstreet Boys” have travelled all over the world but often they don't see much of the countries they visit. In recent years band members Nick, Howie, Brian, AJ and Kevin have been to countries as far as Australia, Spain, and Chile.

Life on tour is very busy with little time for seeing a new country. Howie explains, “We try to see the sights when visiting a country for the first time, but often we only get to see our hotel and the place where we're performing.”

One of the good things about going on tour is the chance to meet fans from around the world. Sometimes they can become overexcited though. In Spain, one girl came up Kevin and grabbed his necklace. His brother gave it to him as a present and he was sad to lose it. On another occasion, some Canadian fans ran after AJ and he hurt his foot while running away.

On the whole, the fans make touring special for the band. When they arrive in a country, there are often crowds of cheering fans at the airport. This makes“The Backstreet Boys”feel welcome even when they are a thousand miles from home.
