Do you agree that music is important in our life? Yes I do, music has certain role completing our day to day activities. Here are some reasons why music is heard everywhere andanywhere. Music is a way to express feelings. When we fall in love, the kind of music we'd listen to would be all about love. When we're sad, we would go for music that is melancholic in nature and immerse ourselves in the sadness. When we're happy, we'd choose songs with happy tunes too. Song can help to memorize the last experiences. A favorite song is a powerful documentary. People with Alzheimer which are impaired the brain would remember details about songs they were familiar with. For example, an elderly woman who couldn't even remember her husband's name wouldremember the details of her favorite song; when it was played, how it made her feel and things about the song that made it especially memorable for her. Further, music can unite people for a cause and changes the world. A song with good lyric and striking deep chord can stimulate the universal feeling of all people. We can see it in the case of the famous and legendary Michael Jacson's Heal the World. It can arouse humanism of a lot people in this world.So what would the world be like without music? It would be lonely.
