Born again - Joonyeong Kim & Minjeong Joo

You must be familiar with the intro of this song. The main key to notice in intro is that the melody has been drawn in sync, but the rest of the notes in the chords come out straight. It's an important skills to memorize. 

Interlude and outro have the same melody and chord as the intro. At this point, the left hand turns into an Arpeggio. So pay deep attention to the small difference that makes music better.

You should also pay attention to how the chorus builds up. Let me show you how J-US performs. This is the way to reduce the explosion effect of chorus. At first, the sound is going softly but the second chorus goes much stronger. I used this way again at the end. 

From 82th bar, you can see its cut down a lot. It goes stronger at 86th bar and much stronger at 90th bar. 

This is how the effect of sound is built up.
