0-20s is the beginning of the music. The type of structure is Crescendi, that is, increasing volume. At first, it is just beat, as the the beat becomes louder, melody is also added. It not only increases the volume to attract listener's attention but also introduce the singer's voice very smoothly. A really nice transition between the pure music to human voice. Just as what is mentioned in the reading "Expansion of register opens up new terrain". From silent to beat then to the terrain of the singer's voice. As a listener, I feel very engaged.
