나의 등 뒤에서 (Behind my back) - Yongduk Choi

I often use this progression when I am accompanying "Behind my back" 

Even three bars are chorded with EM in the part of "일어나 걸어라" 

It's simple using one transitional chord and forward progression. The part of "내가 새 힘을 주리니" is where the chord goes backward so it feels like it you are getting a boost from the beginning. So maybe this is why I like this part of chord progression.

And the Calypso rhythm in a fast song! 

Are you guys finally getting used to this? 

When using the basic rhythm, try to transpass chord from the top note to the melody note. If the melody is mi in EM chord, try to hold sol#si mi this way so mi would be located on the top note. 

Practice this way.
