Text 2 Early Music There was music before there were people to listen to it. Birds sang. Wind whistled, and ocean waves crashed in a steady rhythm. People have probably made music since their earliest days on earth too. Maybe the first human music imitated the sounds of nature. Humans may have created songs in imitation of the sounds of other creatures. As people had words to speak, maybe they also had words for songs. Simple hunting tools might have served as early percussion instruments. Simple flutes made from hollowed bones have been found that date back to 10,000 BC Archaeologists have found evidence that music was played in ancient civilizations including ancient Egypt and Babylonia. As early music was not written down, the earliest evidence of music is in the form of pictures showing musicians and musical instruments. Questions: 1. What was the first human music like? 2. What objects were used as instruments? 3. How do we know that music was played in ancient civilizations? 4. Does music play an important role in your life? Why? 5. Do you enjoy going to concerts? 6. What else do you prefer to do in your spare time? 7. Do you like watching TV? What are your favourite programmes? 8. Do you use the Internet for fun and entertainment? How many hours a day do you surf the web? 9. How often do you go to parties and discos? 10. Are you fond of sport? What sports have you tried? 11. Some people say that books are best friends. Is it true for you? 12. Who do you prefer to spend your free time with? Why?
