History of Technology for Listening to Music
Read the paragraph and identify the verbs. (Không có ô điền, chỉ đọc hiểu.)
Thomas Edison invented the phonograph in 1878. Before that, people could only listen to live music. If you wanted to hear music, someone needed to play or to sing for you. The only other way that you heard music was to play an instrument yourself, or to sing. People sang while they were doing their work or while they were sitting around their house in the evening. Of course, if there was a party, a group of musicians often performed music for the people at the party.
Then, the phonograph changed everything. People could listen to the phonograph while they were cleaning their house or maybe while they were doing some accounting at their kitchen table. Eventually, inventors produced smaller and smaller devices that could play music. Finally, in 1979, Masur Ibuka invented the Walkman, a cassette tape player that was so small that you could carry it with you while you were travelling or exercising.
Who knows what will happen next. The music industry is always looking for ways to expand their music audience and save money. Instead of paying a famous person to create music and sing on an album, the music industry can save money by creating their own music with a computer-generated voice. In addition, Artificial Intelligence means that ordinary people are now creating their own music. They are making their own music on a laptop and (are) substituting their own voice with the voice of a famous singer. Musicians will need to be creative if they want to make money in the future. But they themselves are using AI to create music, and they will still find a way to create a career in music. But maybe we will go back to the past and begin playing and singing ourselves—we will be hearing our own voices again.
