According to my understanding, people who are tone-deaf can improve their musical sense and intonation by practicing some introductory songs. The songs suitable for tone-deaf beginners include Little Star, Happy Birthday Song, Moon Represents My Heart, Jasmine Flower, Fairy Tale and so on. It is very important for people who are tone deaf to choose their own introductory songs. Through constant practice and persistence, you can gradually improve your musical sense and intonation and enjoy the beauty of music.
